"Real CPR looks like real CPR; Movie CPR looks like somebody just kinda, like, heaving against somebody's chest going like, 'Live, dammit! Live!' and just like, pounding his fist against their chest..."Cardiopulmonary resuscitation (CPR) is an emergency first aid protocol for an unconscious person on whom normal breathing cannot be detected. For some very basic RL information on CPR, see the Useful Notes subpage. In TV-land, it's:
- Clean (doesn't take into account hygiene, oral-vector diseases, or any precautions against these.)
- Pretty (it's heroic to know how to do CPR; unless the show is a Sitcom or an anime series, hold the Ho Yay! or anxiety for the perception of same. It also gives a reason for a male character to undo a female one's blouse- or vice versa)
- Reliable (unless the story calls for the character to be Killed Off for Real or Ascend to a Higher Plane of Existence, he'll be back in action, no muss, no fuss. If the character is destined to die, his rescuers will give up the situation as hopeless within just a few minutes.) In fact, a 1996 study published in the New England Journal of Medicine showed that CPR success rates in television shows was 75%.
- R can also be for "Romantic," since the resuscitated character, if of the opposite gender, will often react to mouth-to-mouth resuscitation by kissing their rescuer passionately (or, conversely, reacting with outrage on the assumption that the rescuer was attempting to steal a kiss (or worse) from the victim). This is as opposed to the more realistic reaction of throwing up, groaning and feeling like hell. In fact, today in most cases, mouth-to-mouth isn't even recommended by some jurisdictions.

- Sexy CPR. On the other hand, her technique isn't so bad...
- Completely averted with the Citizen CPR campaign in Ireland. Understandable, as it's a Public Service Announcement. The statistics quoted about death due to cardiac arrest don't apply elsewhere, but the principle is sound and worth a watch.
- The victim in this case not only looks good for a guy undergoing cardiac arrest, he looks good for a guy being worked over by Vinnie Jones. Notably this PSA specifically advises against the "kiss of life" method.
Anime and Manga
- CPR is performed on a drowned girl in the first episode of Mai-HiME, after some brief awkwardness, but no one thinks to procure proper life support in the event she doesn't recover on her own. Naturally she does, spitting up some token water in the process,
- The first episode of FLCL. Played for laughs, though.
- The Vision of Escaflowne - Millerna and Van very much perform the Kiss of Life version on Hitomi. Though it's more realistic in some respects - Hitomi doesn't quite vomit, but she comes close to coughing her guts out and looks half dead for a few minutes.
- Averted in Monster: It's obviously a wasted, desperate effort and the dude obviously stays dead.
- Full Metal Panic? Fumoffu:
- Spoofed. After fishing Sousuke out of the school's pool, Tesse insists on giving him CPR. Sure, that makes sense — Except for one thing: he's already breathing. Seeing as Tesse's mostly just trying to take advantage of the situation for some good ol' lip-locking, Kaname's irritated attempts to point this out don't deter her very much.
- Prior to this, fun is had from Sousuke's complete failure to differentiate kissing from CPR.
- One Piece: Eiichiro Oda seems to like showing off livesaving skills. CPR has been shown in two instances (on Luffy in the Arlong arc, and on Usopp in the Skypiea arc, the latter more Played for Laughs), and implied in two more (on Dalton in the Drum Island arc; on Luffy and Robin after the battle with Aokiji following the Davy Back Fight). Elsewhere, Chopper pounded on the chest of one of Eneru's enforcers after he drowned in a swamp cloud to resuscitate him.
- Sakura from Naruto performed CPR on Naruto in order to keep him alive after Kurama was extracted. This was explicitly noted to be a stop-gap measure until they could seal the other half of Kurama into him. When his heart stopped beating, Sakura averted the trope by cutting into his chest cavity so she could begin massaging his heart by hand to keep blood flowing.note
- In chapter 1/episode 1 of Nagasarete Airantou Suzu administers the Kiss of Life to a half-drowned Ikuto, nearly killing him in the process (inflating him like a balloon, whereupon he flies in a circle before landing back where he started).
- When Haru is unconscious after his fight with Lance (in Rave Master) the older Musica proposes artificial respiration to try and revive him. Elie volunteers and is going to put her lips on his when he wakes up. Haru greets her cheerfully. He gets slugged.
- Slayers has a particularly over-the-top example when Sylphiel is trying to revive Lina. After a few whacks on the chest, a couple of chest compressions, and one breath, she sighs in relief that Lina no longer looks dead... then goes back to casting a long-winded healing spell.
- At least in the manga, Ranma from Ranma ½ is shown to do a variation of this to Miss Hinako (who is shown to comically, as in like a fountain, vomit up water) and implied to do so to Akane a few times.
- In one of the last episodes of Wolf's Rain, Hubb and Cheza perform CPR on Quent when he starts having strange breathing spasms. It's bad enough that they're doing CPR when he clearly has a pulse and respiration, but to make matters worse Hubb speculates that the spasms might be due to internal bleeding or shock from dehydration, neither of which CPR would help with — in fact, it would most likely only exacerbate the former!
- Episode 9 of Angel Beats! shows us some of Otonashi's back story, which reveals several more hours worth of memories before his death, which mostly involve him administering basic medical aid to the survivors of the subway train crash he was in this includes an instance of CPR which is a lot more realistic than usual. It's dirty, exhausting and doesn't work, also it sticks to the rule of only giving up if you become too exhausted Otonashi had to eventually, it isn't clear how long he kept it up but a rescue attempt was several days away - what with them being caved in - and Otonashi himself was suffering from the injuries that would eventually kill him just before said rescuers showed up.
- In episode 1 of Kannazuki no Miko, after catching Himeko from a fall (how this would have stopped her heart is not explained), Chikane rips open her shirt, pauses to fondle one breast, and then does two chest compressions. Himeko promptly moans, demonstrating that she's revived.
- Subverted in The Big O with this quote:
Roger: You could've come up with a gentler way to bring me around, you know. Like, mouth to mouth, or something?
Dorothy: Not with the displacement capacity of my air tank. You're such a louse, Roger Smith.
Roger: Heh, you're definitely our Dorothy.
- Guts performs CPR on a drowned Casca at one point in Berserk. Curious enough where he learned to do that in the Dung Ages, but it resuscitates her after a few repetitions all the same.
- Lampshaded in Excel Saga when the municipal employees are unwittingly sent to locate the ACROSS base: Iwata goes through all the proper steps in administering CPR in a bid to get to kiss the unconscious Matsuya, including calling out for someone to retrieve a medical professional, despite the fact that they are stranded in Fukuoka's sewers without another living soul in earshot. She recovers before their lips make contact; despite it being blatantly obvious Iwata was trying to steal a kiss from her, she actually goes easy on the inevitable retaliation (that is, he lives) out of respect for him doing everything by the book. Played dead straight when Iwata is later forced to resuscitate his male teammates with CPR.
- Rahzel performed CPR on Rayborn in chapter 34 of Dazzle after his fake suicide attempt backfires. Perhaps more realistic because he passes out afterwards, but that's cancelled out by Rahzel's decision not to take him to a hospital because she thought he'd be embarrassed to wake up surrounded by doctors and his family.
- In Star Driver Wako preforms CPR on Takuto after finding him washed up on the shore. Later the characters discuss the romantic implications.
- After an encounter with a lake demon in Inuyasha leaves Sango unconscious, Miroku decides that he needs to resuscitate her - only to be left protesting his innocence after Sango regains consciousness to find his face inches from hers and comes to the predictable conclusion, with the predictable result.
- A variation in Life. Miki had fainted so Ayumu attempted to revive her by giving her water. She couldn't do it though, so she instead drank some water and swapped it with her. Despite how gross that sounds it didn't look as bad as it seems.
- Averted in the Manga IO: Its one of the few correct depictions of CPR in manga. Even the translator comments on it.
- In the manga of Air Gear, Agito is somehow able to perform this with a bamboo stick. Really. And it works, no other life support necessary!
- In the second volume of Jyu-Oh-Sei, Thor, after fighting the Top, is wounded so severely that his heart stops. Third and Tiz preform CPR on him pretty accurately, but what really takes the cake for being over the top is when Third starts slapping Thor; what's worse is that it alone is what actually revives him!
- A Cruel God Reigns:
- Ian helps Jeremy breathe and exchanges liquid medicine via mouth-to-mouth after Jeremy's drowning Bungled Suicide.
- It is not so clean and pretty when Marjorie tries to drown herself in the bathtub and Lorenzo has to give her CPR. It is also not reliable because she ends up in a coma.
- Oreshura, from Episode 5:
- Eita is forced to do this for Masuzu shortly after he rescues her from drowning in the school's swimming pool. He calls for the teacher, but notices that the teacher is giving CPR to another student. And as he does this, he hears some Squee! from his classmates as he "kisses" her.
- Later in the episode, while watching over his sick Childhood Friend Chiwa, she talks in her sleep about wanting "CPR" from him as well, having gotten a text about the CPR he gave Masuzu earlier.
- In Attack on Titan, Hannah attempts this on Franz, even asking Armin to help her. It fails because Franz's... condition isn't really one that can be fixed by CPR.
- In an arc of The Avengers called "Red Zone", Captain America is exposed to a contagious evil bacteria and stops breathing. Saying, "Sorry Tony... but Captain America's more important than you", Iron Man immediately takes off his helmet and starts mouth-to-mouth. (With dramatic lighting and close-ups!) The "CPR revives people by itself" aspect is theoretically averted, as his goal is to keep Cap alive until he can be rescued, but ultimately used straight as, minutes later, Iron Man is passed out and Cap is weak and disoriented, but on his feet. Must be the Super Soldier Serum.
- In the first volume of Runaways Gert uses CPR on Chase after he's been submerged in water and stops breathing. He feels pretty crappy immediately afterwards, but recovers pretty quickly.
- In Young Avengers, Wiccan revives Iron Lad pretty easily through CPR, but the Clean part at least is averted when Iron Lad spits up in his mouth. Wiccan also lampshades the Pretty aspect as he admits that he only learned it to be able to kiss a boy he'd had a crush on.
- In an X-Files comic, Scully performs CPR on a man in cardiac arrest. In a minor subversion, the comic actually points out the need to break the ribs to properly massage the heart, but just CPR is still enough to stabilize him.
- Averted at the climax of Doctor Strange: The Oath. Strange's associate Wong falls unconscious with no pulse from a brain tumor. Another physician says she can do CPR to try to restart his heart, but even if he lives, Wong will only be a shell of his former self. Wong survives and recovers only because Strange retrieves a Magic Antidote — the CPR just keeps him slightly alive so that the potion can heal him.
- In The Joker: Last Laugh, Nightwing, believing that Robin has been eaten by Killer Croc, goes in an all-out frenzy and beats up the Joker to the point where his heart stops beating. Fortunately, Batman stops Nightwing in time before the Joker collapses, almost nearing death, and the Dark Knight resuscitates him using CPR in order to stop Nightwing from stooping down to the Joker's level as a murderer.
- Parodied in The Lion King Adventures. In Dead as a Dodo, Simba and Nala think that they have accidentally murdered Zazu when a prank goes wrong. Simba resorts to giving him CPR, by punching him in the chest.
Simba: Live, darn it, live!
(Nala pulls him away.)
Nala: Simba, Simba! That's not helping!
Simba: No, but it's making me feel better.
- In Undocumented Features, Corwin receives an electrical shock, and it falls to Utena to save him with CPR. However, what saves his life is not CPR, but the Power of Dios.
- In Letters: The Year With the Stone Hermione gives a partially-asphyxiated Snape CPR and he's up and about within a minute or so.
- Averted in Prison Island Break. Doctor Amy Rose Blossom performs CPR on Shadow the Hedgehog. She has to suck the blood and vomit out of his mouth to keep him from drowning, while considering how likely he is to die. It's explicitly unromantic, especially since at one point she tires and Silver has to perform it (in real life too, if you get tired, you swap out with somebody else). Silver does exactly as she commands him while contemplating how his entire medical experience revolves around watching repeat episodes of Scrubs. On the whole it is suggested that what leads to Shadow's survival is his superior healing abilities.
- Another aversion occurs in A Kingdom Divided. When Cloudchaser tries to resuscitate Rainbow Dash she starts with checking her mouth for 'foreign objects,' and the whole scene ends with Rainbow Dash dying.
- In the Kingdom Hearts fic Another Side, Another Story, after his Love Interest/sidekick West is nearly drowned by Ursula in Atlantica, Riku swims her to the surface and revives her with CPR, reflecting that it was mandatory for everyone on the Destiny Islands to learn it.
- Partially averted in Harry Potter and the Escape to New York. While it takes only a minute or two to work, there's absolutely nothing pretty about it and Harry ends up with two broken ribs.
- In Potter's Protector CPR fails completely at first and Harry has to resort to using a lightning spell to imitate a defibrillator.
- In Nowhere, a girl pulls a drowning boy from a pool and breathes into his mouth once before he lives again.
- Used in the first Jurassic Park, after Tim was electrocuted by the fence Dr. Grant spent a few moments trying to bring him back, which worked so well Tim finished his last sentence. Though they did make some token gestures indicating that he was not completely fine, such as burnt hands, bleeding ears and a limp for the rest of the movie.
- Averted in Empire of the Sun. Jim attempts CPR twice in the film. Not only does it not work in either case, the second time (where Jim tries bringing a pilot back) is far from pretty.
- The Abyss: While the technique does succeed in reviving an otherwise deceased person, it's neither clean nor pretty, and it goes on for several minutes, rather than less than one. Truth is, while it's still not a completely realistic depiction, it's still several steps ahead of most.
- Although an attempt by Bond on Vesper fails in Casino Royale (2006), it still counts as (a) Bond gives up less than a minute into administration, and (b) his technique doesn't focus so much on restoring circulation as copping one last feel.
- In the recent Nancy Drew movie, Nancy performs CPR on someone who is pretending to choke.
- Averted in The Orphanage - the woman being resuscitated didn't make it, and brief glimpse to her face shows that her entire lower jaw was horribly dislocated by the car that hit her, showing that the guy giving CPR had really strong stomach, though being a trained doctor probably helped.
- Star Trek VI: The Undiscovered Country has Dr. McCoy attempting to revive a Klingon who has been shot in the chest. His heart isn't beating, so McCoy tries CPR for a few seconds and then gives him what may be the now-outdated "precordial thump", which brings him back to life long enough to utter appropriate final words. However, in some rare cases, a physical jolt to the heart like that can indeed take it out of fibrillation. SF Debris refers to this as Cardio Plot Resuscitation as it revives the patient long enough to move the plot forward. McCoy does point out he doesn't even know Klingon anatomy; he may be trying anything he can think of, desperately hoping he gets lucky. He was also drunk.
- Spider-Man Trilogy:
- Spider-Man: A lab assistant begins CPR after Norman's heart stops. He's giving him sideways chest compressions from a standing position and it only takes TWO to start Norman's heart again.
- Spider-Man 3: After Harry is injured, Peter attempts the hands only method for a few seconds before giving up and taking Harry to the hospital. Can be justified to a certain extent in that Peter probably didn't know what he was doing and figured it would just be simpler to get Harry in the hands of a professional as soon as possible.
- In E.T. the Extra-Terrestrial, this Trope was averted; the CPR the doctors used to attempt to resuscitate E.T. was actually rather realistic, and it seemed to fail to their (and likely the viewers) heart-wrenching regret. (Of course, they didn't realize that he was Only Mostly Dead and they simply couldn't succeed in saving him that way; he could only save himself when he realized that his kinsfolk were coming.)
- Played straight in The Haunting in Connecticut. Since the receiver of the CPR was possessed by a spirit at the time, and was only brought back after said spirit left his body, this may be justified.
- In Teenage Mutant Ninja Turtles III, after Michaelangelo rescues Yoshi from the burning house, Leonardo attempts CPR on Yoshi. During this, Mitsu clams he's 'casting an evil spell', but April corrects her that 'he's helping'.
- During the end of the movie Fearless, Laura Klein (played by Isabella Rossellini) gives CPR to her husband Max Klein (played by Jeff Bridges) after eating a strawberry. During this, we see flashbacks of Max's experience in the past plane crash while at the same time, during CPR, we see a bit of drool from her mouth when she's desperately is trying to revive him.
- Honey, I Shrunk the Kids - Acts as a first kiss between the two teen lovebirds
- In Kiss Kiss Bang Bang Harry gives Perry very bad CPR after he is shot through the chest, and only gets a mouthful of blood for his trouble.]]
- Mission: Impossible III has Ethan receiving CPR from his nurse wife after electrocuting himself. Complete with dramatic punching of the chest!
- Averted in Terminator Salvation, where John Connor attempts to revive the dead Marcus through two Precordial Thumps before tearing two wires out of the wall and giving him an improvised defibrillation.
- Appears in An Officer and a Gentleman, when Sgt. Foley has to administer CPR on one of the recruits after an accident with a crash landing simulator.
- In a variant, The Twelve Chairs (set shortly after the Russian Revolution) uses the older Schafer method, with the resuscitated woman lying on her belly and the rescuer kneading her lower back. It's still this trope in the Pretty sense, as they were actually fooling around and only adopted this ruse of respiratory distress because there was no time for her to re-tie her underthings when her husband came home early.
- Averted in Groundhog Day. Phil spends several of his loops trying to save a homeless bum who dies in an alley. He spends hours doing CPR on him. He even takes him to the hospital before he even has problems. He's never ever able to save the guy. The nurse in the last attempt suggests he just died of old age, and Phil realizes he simply cannot save him no matter how hard he tries.
- Played for laughs in The Sandlot where Squints intentionally jumps into the deep end of the pool so that he'll be rescued by his crush the life guard. After a few tries of CPR, Squints pulls the life guard into a big kiss.
- It's played for laughs in Thor, where after accidentally running Thor over with a car and upon seeing Thor (and he was conscious and breathing fine on his own), Darcy was quick to point out she knows CPR to help him.
- In The Avengers, Tony Stark/Iron Man was happy that he woke up before this happened to him.
Please tell me nobody kissed me.
- In Young Dr. Kildare, Kildare performs artificial respiration on a woman for half-an-hour. After the woman revives she's perfectly fine. Revival after 30 minutes of being clinically dead is virtually impossible, and if it did happen it would come with massive brain damage.
- In Like Flint. After shocking a guard's heart back into beating, Flint does some mild chest compression on him and he revives.
- Averted in Sherlock Holmes: A Game of Shadows where Watson's chest compressions weren't able to revive Holmes. Instead, he had to use adrenaline. After Holmes is revived, he mentions his chest really hurts. It also averts Magical Defibrillator as adrenaline is what is actually used to restart a heart that has completely stopped. However, the use of CPR at all in this scene is still an anachronism; as noted above, it wasn't invented until the 1950's.
- In the 1992 version of Only You, Cliff goes snorkeling alone, ignoring the advice from an experienced snorkeler to "watch out for the kelp beds". It cuts to him coming to on the beach, horrified to think the ugly old woman above him just gave him mouth to mouth.
- Subverted in Angels & Demons. When the second preferiti is found, the main characters attempt to give CPR in a realistic fashion, with one providing breath and the other getting ready to do compressions. However, the attempt is anything but clean; the preferiti has two holes in his lungs, causing blood to spray out and into the face of the poor guy standing over him. Needless to say, he doesn't survive. Later, it's also tried again unsuccessfully, with the final kidnapped victim who was drowned in a fountain.
- Averted in Earthly Delights by Kerry Greenwood. When the heroine finds a junkie who overdosed on her grate and gave her CPR, she placed plastic wrap over the junkie's mouth (and put a fairly large hole in it for the air) so she wouldn't catch anything.
- Averted in Johnny and the Bomb as Yo-less briefly considers performing CPR on Mrs. Tachyon but the gang decides to just call an ambulance instead for hygiene reasons.
- The Dresden Files:
- In the novel Storm Front, Morgan having rescued Harry from the burning building, revives him using CPR. Neither of them is terribly happy about it, but it worked.
- In the short story "Something Borrowed", Harry uses CPR to revive Murphy after an evil faerie crashes some friends' wedding and tries to drown them both in the punchbowls. His narration says it momentarily felt a bit like a kiss, just before she starts coughing up inhaled fruit punch.
- Later, in Small Favor, Dresden is on the receiving end of CPR from Murphy. Averted when he vomits on her.
Dresden: Guess we're even.
Murphy: Like hell we are. I only spat fruit punch in your mouth.
- Done in Thieves Like Us, when the Big Bad accidentally shoots the ancient mummy-like leader of an ancient cult then attempts to perform CPR to revive him. It doesn't work and there is mention that his nose is pulled off when she grips it (yes, that's how old he is).
- Averted in the Mercedes Lackey book Sacred Ground. A housewife has been cursed by malevolent spirits, who cause lightning to hit her child. She has her other child call 911 and starts both CPR and chest-pumps with counts for each, and keeps doing this until the paramedics arrive. He's dead.
- CPR works just fine to bring Nikolas back to life at the beginning of Closer to Home. He's in lousy shape afterwards, but how much of that was pre-falling in the icy river injuries and how much was from the CPR isn't stated.
- Subverted (or possibly averted) in Artemis Fowl: The Time Paradox: after a character collapses from magically-induced cardiac arrest, instead of doing CPR, Artemis simply grabs a (conveniently nearby) defibrillator and revives him with that.
- Averted in The Ruins. Jeff preforms CPR on Amy for hours before being forced to give up due to exhaustion.
- Subverted a couple of times in the Discworld series. Usually the mere threat of the "Kiss of Life" (especially from Nobby) is enough to revive the patient. Most of them haven't really suffered cardiac arrest, they've just fainted.
- In The Underground, Arnold Schwarzenegger gives George Edelman mouth-to-mouth after rescuing him from drowning in a river (where the Animorphs, as birds, had carried George after he tried to jump out of a building).
- Later averted in book 19, in which Cassie receives CPR and the first thing she does when recovering consciousness is vomit over herself. She spends a while with numb extremities as well.
- In the YA book My Angelica, there's a scene in Sage's story where Angelica performs CPR on -the number keeps changing- Bears...after he passes out from choking on raccoon meat. Her Unlucky Childhood Friend tries to tell her that A; the way she wrote it wasn't how it's normally done and the man revived too fast, and B; it's the Heimlich Maneuver she wants, not CPR. She doesn't listen.
- In Orson Scott Card's Ender's Shadow, Bean is the first of the children to realize that Bonzo Madrid is dead after the fight with Ender when he sees the medical staff performing CPR on him. For the record, Bean is 6, but has been genetically-engineered to be a savant.
- In Catching Fire Finnick performs CPR on Peeta (whose heart has stopped) for several minutes before they cough and sputter to life.
- Jacqueline Wilson's Buried Alive involves this trope in the climax. Protagonist Tim gives this to the primary antagonist after digging him out of a caved in sand cave the idiot had been digging. While it is reliable, it isn't pretty as the recipient vomiting is the sign that it's worked, and the clean part is half averted in that Tim wipes away as much sand as he can from the mouth before attempting CPR.
- Rand al'Thor provides this for Mat Cauthon in the abandoned city of Rhuidean after the latter has been hanged. It's almost comical in that Rand probably shouldn't know about it (it's thousands of years in the future, but after a massive apocalypse) and that Rand gets it so badly wrong (probably even in-universe; Rand's only seen it performed on a drowning victim, so he goes through a lot of motions clearly meant to get water out of the lungs). Mat gets better anyway. Must be ta'veren at work.
- Averted in The Throne of Fire, at least the "pretty" part. When Carter Kane does it on Zia, she immediately tries to punch him upon being revived.
Live Action TV
- Averted where a drunk and passed out partygoer vomits into the mouth of Dr. Carter when he tries to administer CPR.
- Averted in early episode had Carter giving CPR to an elderly gentlemen while nurses prepared to defibrillate. He then proceeds to break the old man's rib with a loud crack.
- Averted in Casualty 1906, which is set before CPR was invented.
- Subverted in Cardiac Arrest with a patient suffering from multiple broken ribs. From the look on the junior doctor's face, suddenly realising you've crushed a man's chest is not nice.
- In the "Prophecy Girl" episode of Buffy the Vampire Slayer, Xander revives Buffy with CPR and she recovers fully and quickly. Buffy is a Slayer with supernatural healing ability, which makes it more acceptable. A more realistic depiction is in the episode "The Body" — Buffy attempts CPR on her mom and breaks a rib, which is common even without Slayer strength. This is also a rare case of it failing (although it's also one where it would be incredibly ridiculous for it to succeed, given that the cause of death was a brain aneurysm). Buffy's not even sure if her mother is alive at this point. What sucked was that Buffy had to be talked through the procedure by the 911 operator.
- Dollhouse manages to walk its way into this one with a near-audible "thud". At the end of "The Attic", Echo manages to unplug herself from the neural network by flatlining her vitals and coming back. Victor and Sierra, not as special, however, need help coming back from the dead, and badly-administered CPR seems just the ticket.
- In Xena: Warrior Princess, Xena accidentally invents CPR to save Gabrielle's life after a seizure (caused by a head injury) apparently kills her. ("She just needs air. I need to get some air into her lungs!" and, later, sobbing and pounding on her chest as she demands that her friend "Wake up! Wake up! Wake up!") Being her love int—er, sidekick, Gabs does. Gabs' reaction is an aversion of the trope: Although the newly-resuscitated Gabrielle doesn't vomit, she is white as a sheet, sweaty, trembling, staring, thoroughly disoriented, and looks as though she would very much like to spew her guts.
- MacGyver, episode "The Enemy Within": MacGyver and a friend apply CPR to the victim of an induced heart attack, demonstrating technique that would make a first aid teacher fail them on the spot, and keeping at it only long enough to show they tried before giving up and saying "He's dead" in a suitably dramatic voice. Later in the same episode, there's also a dodgy scene involving a defibrillator.
- Nearly every episode of Baywatch included a swimmer drowning or near-drowning in the ocean, only to be pulled out by a lifeguard and given CPR for a few harrowing seconds before coughing up some water and being as good as new. Averted in some episodes, especially in the first 2 seasons (before Pamela Anderson), when CPR is used just to stabilize the victim until defibrillator arrives or is ready. Especially in rescues involving the Scarabs. In one S1 episode there is even a mention when one of the characters is rescued by an amateur lifeguard only to have breathing problems later that night, that every rescue by a professional lifeguard is finished at the hospital, where the victim is checked.
- Lost: This trope was almost averted in the first season, when guitarist Charlie Pace is hung from a tree while attempting to rescue fellow survivor Claire. When he is found by Jack Shepard (a doctor) and Kate Austen, Jack tries CPR on him for three minutes, but it doesn't seem to work. The music plays very somberly, and it looks like he is dead for good... until Jack starts yelling at him to wake up, and keeps pounding his chest until Charlie comes to. So close.
- Episodes of both Law & Order and CSI: New York have had HIV-transmission scares from giving artificial respiration, so yay for recognizing that stuff can be transmitted. Even better, both series also note that it's vastly unlikely for HIV to go through saliva.
- Criminal Minds:
- In one episode, a character attempts CPR on his subordinates, but only succeeds in breaking their ribs, and is later taunted with the true statistics of CPR.
- Played straight in a later episode, where it's used to revive a young girl who's been without air for something like seven minutes. She gets up and walks home with her parents.
- One serial killer drowned and then revived his victims, hoping one would have a near-death experience and could tell him about it. "Reliable" is subverted, as all of them wound up dying permanently.
- Doctor Who:
- There is a deliberately ludicrous example in "The Horns of Nimon", when the Doctor attempts to perform CPR on K-9, a robot who does not breathe and whose reason for malfunctioning was his head coming off. He stops doing it after a little while after realising it's stupid.
- In "Smith and Jones", CPR is performed on The Doctor, even though his problem required a blood transfusion, not CPR. POSSIBLY justified as the Doctor is not human, so it could be chalked up to Bizarre Alien Biology. The Doctor was obviously not dead yet or he would've regenerated.
- When Martha finds Jack unconscious outside of the TARDIS, and later when he electrocutes himself. The Doctor tells her not to bother, with good reason.
- In "The Curse of the Black Spot,"Rory, who is on alien life support, talks Amy through how to do CPR so she can do it on him once she and the Doctor rescue him. After about a minute of really poorly done CPR, Amy gives up. A few seconds later, Rory starts coughing, sits up, and is fine.
- In (the American version of) Eleventh Hour, a show about a scientist using science to combat pseudoscientific practices, said scientist brings a person back to life using CPR, heart monitor spiking and all.
- In Law & Order: SVU, one episode has main character Elliot Stabler hit a suspect, once, when trying to arrest him. The subject then collapses and, after a few seconds of checking for a pulse, Stabler starts CPR. Said CPR is performed for approximately 20 seconds before his partner, standing 5 feet away and not bothering to help, exclaims, "He's dead...", at which point Stabler gives up. It does turn out that CPR couldn't have saved him anyway and giving it ruptured the man's spleen, making it an aversion.
- The X-Files:
- The show puts a paranormal take on CPR in the episode "Oubliette", where Mulder tries to save a drowned girl but his CPR seems futile. But because the girl has a strange physical-psychic transference link to another person, she suddenly revives while her 'partner' is found dead, drowned despite sitting in a police car nearby.
- In one episode, Scully (the MD) declares that someone has a heartbeat but isn't breathing, and then begins chest compressions.
- In the first movie, Mulder gives Scully CPR on the alien ship. While she doesn't precisely vomit, she does cough up a lot of green alien goo, and there's a nasty amount of retching involved. Gillian Anderson said that was definitely her least favorite bit of filming.
- When Denny has a heart attack in season five of Boston Legal, everyone thinks he's faking until Alan realises he's not breathing and leaps in to save him. Slightly more realistic than usual, as an ambulance is called and we don't see Denny conscious again until he's on his way to the hospital.
- In Season 2, Jack saves Nina by giving her a few mouth breaths, without fixating her chest or using any compression at all. It works.
- The Reliable part is averted in Season 4, when Paul Raines dies after Jack forces the doctors at gunpoint to work on another patient with critical information. It should however be noted that the attempt to save him is rather pathetic, and he's declared dead a mere minute after he crashes. This all takes place in a fully equipped medical facility, and the doctors stabilise the other patient a few minutes later, which would have still given them plenty of time to try to revive him, particularly if Jack and Curtis had continued with CPR in the meantime.
- Family Matters: Urkel saves an electrocuted Carl with CPR, he remembers to get a CPR mask out of Carl's first aid kit, preventing any mouth contact. However, true to the trope Carl revives with no apparent problems.
- Averted in the season four episode "Breath of Life" for The District. Sergeant Brander performs CPR on another officer, using it the proper way to keep the victim going long enough for an ambulance, after the victim's partner refused to do it because the victim is gay. Brander forgetting, in a tense situation, to use a mouth guard makes for a minor bit of suspense, as he waits for test results about whether he caught any disease (particularly AIDS) from the victim.
- One episode depicted it as a semi-romantic kiss between two love interests involving no chest compressions- averted in that it was just used to keep the victim stable until medical help could arrive.
- Later done by Allison Blake attempting to revive a man with chest compressions alone. (Hands-only CPR is medically acceptable).
- Played with in the pilot of Arrested Development; Tobias lost his medical license as a result of incompetently applying CPR to an elderly man who was simply taking a nap.
- Stargate Universe: To break Col. Telford's brainwashing, Young seals him in a room and evacuates the air. A few seconds after he takes his last breath, Young orders the room repressurized and rushes in, drops to his knees, and starts compressions without a pause, without checking Telford's airway, or really even so much as looking at him. Naturally, Telford is breathing and conscious within a matter of seconds.
- In the Farscape episode "The Flax", John and Aeryn have to depressurise and then repressurise their spacecraft with only one working spacesuit between them. The solution: stop John's breathing with a Peacekeeper poison and then resuscitate him with CPR! And his only complaint is that the poison hurt more than Aeryn told him it would.
- An episode of classic Star Trek, "The Paradise Syndrome", features Kirk using a (now outdated) variant of the Silvester Method on one of the locals.
- Averted in an early episode of M*A*S*H when Hawkeye had to perform open heart massage to resuscitate a soldier. The soldier didn't make it. A few seasons later, when newly-arrived BJ Hunnicutt was trying to resuscitate a soldier, Colonel Potter asked if he was going to use open heart massage. BJ answered, "I can do it closed. I've seen it done in the States."
- Played both Clean and Reliable on the episode of The Jeffersons in which George winds up using the technique to save the leader of a KKK group, although the KKK leader still has to be taken to the hospital afterward.
- In Herman's Head, Herman's CPR usage on a friend ends up cracking some of her ribs. Unfortunately a lawyer seems to take advantage of the general lack of knowledge of CPR risks to get the friend to sue Herman for the injuries.
- In a first-season episode of Charmed, Andy brings Prue back this way. She coughs a little bit when she starts to come back, but not very much and it very quickly turns into a hug. Possibly justified given that Prue's stopped heart was intentionally induced using a potion from the Book of Shadows, and she explicitly stated (to Phoebe; Andy had no idea what was going on) that it was completely reviveable with CPR as long as the CPR was administered within four minutes of taking the potion.
- A form of Bait-and-Switch Credits is used in Ashes to Ashes when previewing Episode 6 of Season 1. Gene is pictured about to kiss Alex. The reveal is that it's only CPR after she is rescued from a refrigerator in a restaurant used as a front for money-laundering.
- Used in the online-only webisodes for The Walking Dead, which you can watch here (CPR happens first thing, not safe for kids gore.) First off, the woman preforming never calls for help. While the woman checks for a heartbeat, the zombie's eyes open. If the woman would have at least looked at the face she was about to put her lips on, we could have avoided all of this.
- Done surprisingly well in a recent episode of The Mentalist - certainly, it IS pretty, but quite realistic anyway (automatic defibrillator!) and the "reliable" part is justified (the reason for passing out is drowning, which tends to come with a better prognosis).
- Burn Notice is usually fairly realistic when it comes to things like this, but in the season finale of season 6, Sam's heart and breathing stop due to a bullet wound that couldn't be treated immediately, Michael administers CPR for about 10 seconds, and Sam makes a full recovery with no immediate adverse effects (other than the effects of having been shot.)
- Subverted fairly realistically on Breaking Bad. After accidentally beating an underling to death while high on meth, Tuco demands that Walt, the "scientist," perform CPR on him. It's pretty obvious that Tuco got all of his information about CPR from TV. Needless to say, his attempts have no effect.
Tuco: What are you doing? Don't just push on him! Do the breathing in his mouth thing!
Walt: (more than a little hysterical) They don't teach that anymore! It doesn't work!
- Played straight in "And the Window of Opportunity", the second-season finale of 2 Broke Girls, when Caroline revives Max that way after an electric shock knocks her unconscious.
- Doc Martin: Morwena manages to revive her grandfather with a good minute and a half worth of this.
- Lampshaded on "Murdoch Ahoy" of Murdoch Mysteries. Detective Murdoch is saved from drowning by his Love Interest Dr. Julia Ogden who dives for him, takes him out of the water and gives him CPR. Inspector Brackereid just stares at her and doesn't understand what she's doing. Later when they're back at their Station House, he jokes that while his best man was fighting for his life, she only used it as an opportunity to smooch him. She tries to convince him that mouth-to-mouth resuscitation is a real medical thing used in Switzerland to save babies.
- The Star Trek: The Original Series episode "The Paradise Syndrome" literally adds insult to injury by Kirk having to teach the technique to primitive Native American stereotypes, using the now horribly outdated "leg pumping" method.
- The Ranch : Colt performs CPR on a newborn calf that appears to be stillborn. Not only does he bring the animal back to life, he's so good the calf is brushed and dried of all the birth goo coating it to that point!
- Code Black averts this in every conceivable manner. Nobody ever tries to shock a flatline* . Last-ditch CPR tends to involve cutting open the rib cage (usually at Center Stage) and starting internal cardiac massage, and this only works rarely, as in real life. Most situations with successful CPR involve an abnormal heart rhythm that's restored with only a few shocks, as in real life; by the time the patients are in cardiac arrest, the doctors' resuscitation efforts usually fail.
- In Red vs. Blue Grif somehow uses CPR to save Sarge from a sniper round to the head, and they were both wearing helmets the entire time. Doc later tells him that was the best thing to do (FYI, he's not a very good medic). Lampshaded when Sarge, annoyed at having to admit Grif did something right and incredulous at his methodology (which he praised Simmons for until corrected), asks, "What would you do if they stabbed me in the toe? Rub my neck with aloe vera?" Further lampshaded when Caboose gets shot in the foot, and Doc responds predictably.
- This is parodied in the Supermarioglitchy4s Super Mario 64 Bloopers 2015 Halloween Special, where Waluigi attempts to do CPR on Wario, and it doesn't have anything to do with chest compressions or mouth-to-mouth. He just kisses Wario.
- Subverted with Baywatch; the "CPR" mode is fairly difficult to accomplish, due to the steep Guard Tower ramp and the priority of ball locks on the ramp.
- Averted in Dino Attack RPG. CPR doesn't revive a patient whom the doctors have just had to overdose on adrenaline, neither does a defibrillator. However CPR in the form of hitting her with a shark works perfectly, and the first thing she does upon waking up is vomit all over the man who just revived her.
- Played straight in the Xbox Live Arcade game Castle Crashers, as other players can practically instantly revive a defeated ally by pumping on their chest. Probably an Acceptable Break From Reality, and considering the game's atmosphere... not so unexpected.
- Played completely straight in the Sierra game Codename Ice Man. In the opening area, a girl swims out to sea, and promptly needs saving. The following procedure has to be done according to the handbook that came with the game, otherwise the girl dies, and well you lose puzzle points.
- Shortly after the Resonance Cascade, you find a scientist performing chest compressions on a security guard. Realistic in that he never stops, but played straight in that the security guard immediately recovers.
- Opposing Force had another scientist in the middle of performing CPR on a soldier just as Shephard wakes up at the beginning of the game. After a few seconds, the scientist gives up and addresses Shephard, saying that at least "[his] life-saving efforts weren't completely in vain".
- Averted in Black Mesa: the scientist constantly performs chest compressions to the guard, but he doesn't recover.
- Final Fantasy VII had Cloud, who had not been trained, perform mouth-to-mouth on a 9-year-old girl. However it does seem to have that less-than-5% success rate with how frickin' hard it is to do!
- In the Grand Theft Auto series, NPCs who are beaten up or shot to death can be CPR'ed by paramedics who arrive at the scene. The poor victim will then get up and be back to full health, after which you can beat him up again. Rinse, repeat. Repeatedly killing gangsters in this manner can be used in San Andreas to start a turf war in sparsely-populated territory.
- In Trilby's Notes, the title character is revived via CPR after a fatal stab wound. The sequel reveals that he was really revived by gaining the life force from a future clone.
- In Fahrenheit, you can at one point drag a small boy out of a frozen lake and give him CPR. You can easily lose the segment if you're not fast enough, and doing so nets you a game over.
- Also by Quantic Dream, Heavy Rain has you perform CPR on Shaun if you free him from the water pit thing. It's impossible to fail it.
- In The Punisher (Capcom), the Continue screen shows your character receiving CPR. The only true salvation in this scenario is the quarter in your pocket.
- In Metal Gear Solid 4 Johnny gives CPR to Meryl after she drowned. She did spit up water after that but she was revived.
- At the end of Syphon Filter: Logan's Shadow, Lian administers CPR to Gabe after he is shot. It is unknown whether he survives.
- Played straight and used to up the (quite bountiful) Les Yay in Aoi Shiro when Syouko does this to a formerly drowned Migiwa.
- Played straight (but just to mess with you) in The Walking Dead, where Larry has a heart attack and you have a choice; bash his head in or preform CPR. If you're fast enough on the CPR they will come around but only for a second before their head is crushed with a salt lick. It could be that he's coming back as a walker.
- In Chapter 9 of Hotel Dusk: Room 215, Mila falls unconscious and Kyle has to perform this to save her.
- Averted in Cadenza 2: Kiss of Death. The main character performs CPR on her fiance but he still ends up unconscious and dying in the hospital. Saving his life properly is the focus of the next part of the game.
- In The Legend of Heroes: Trails of Cold Steel, if you choose to do a study session with Crow in Chapter 3, he teaches Rean about CPR, and then suggests that CPR on a pretty girl is a gateway to "fireworks."
Rean: Every time I think anything positive about you, you go and say something like that...
- General Protection Fault: When a flood occurs in a 2001 storyline, Nick nearly drowns while trying to rescue a mother and child from the floodwaters. Ki ends up giving him CPR. Though he appears just fine initially, he does end up getting sick, somewhat subverting the trope.
- Spinnerette: Demonstrated briefly here.
- Sticky Dilly Buns mentions "CPR" here, but it appears from that and subsequent strips that this doesn't even mean "real" Hollywood CPR — just some brief mouth-to-mouth resuscitation.
- Protectors of the Plot Continuum: Humorously averted in one story, in an incident where a Sue nearly drowned and the agents assumed her lust-object was going to perform CPR:
"You're kidding. He's going to give her the Heimlich manoeuvre? But that doesn't help someone who's drowning! That's designed to help choking victims!"
"Don't be silly, Isaiah. It's not the Heimlich manoeuvre, it's the Hemlic manoeuvre. My turn for filling in the wrong word!"
Isaiah watched with fascination as Ublaz gave the Sue the Hemlock manoeuvre.
- The SML Movie "Bowser's Depression" has Bowser hanging himself in the bathroom following his favorite show's cancelling. When Chef PeePee notices this, he realizes Bowser is not breathing and performs mouth-to-mouth and chest compressions on him.
- Online roleplayers tend to avert most of the points of this, if only for the hilarity of the recipient suddenly waking up and barfing into the other person's mouth as soon as s/he attempts to give mouth-to-mouth. This means it still has a 100% success rate, though, even if nothing is actually done before they try mouth-to-mouth.
- Debunked in Lifehacker's "Five Survival Skills the Movies Taught You Wrong".
- In the Drawn Together episode Unrestrainable Trainable, Foxxy Love performs CPR on Wooldor Sockbat after he's pushed into the pool by Clara in an attempt to baptize him when she mistook him for a Jew. To her defense, the show isn't exactly known for playing by the laws of reality.
Foxxy: (in British accent) Capital! Thank goodness I'm certified in cardiopulmonary resuscitation! (normal voice) Mouth to mouth, y'all!
- This used with some justification in the Gargoyles episode "Hunter's Moon," where one gargoyle, Angela, is seriously wounded and the clan's human ally Elisa performs CPR. Here, the point is not to revive her, but to keep her alive for just a few minutes until the sun rises—gargoyles turn to stone at dawn, but during their stone sleep they heal of even the most serious injuries. When she "wakes up" that evening Angela is at full strength and ready to go back into battle.
- American Dad!:
- Perhaps the cleanest, prettiest, and most reliable version of CPR shown on TV was in one episode, where Roger passes out after choking on an unspecified foodstuff. Steve, who had become impromptu certified in CPR the previous day, immediately jumps to his side without even thinking about checking for a pulse or other vital signs, claiming "I know CPR!" before bringing him back from a potentially fatal situation with two breaths and no use of chest compression whatsoever.
- In another episode, Steve's chain smoking swimming coach gives him CPR... while still smoking a cigarette. Naturally, tongue is involved. Not exactly pretty.
- X-Men, the 90s Animated Series: When Cyclops passes out after a couple seconds' exposure to toxic gasses, Rogue gives him CPR to return him to normal and it never comes up again. (However, she gains his uncontrollable Eye Beams from the Kiss of Life.) This is especially silly since Rogue's power, in addition to giving her the abilities of the person she touches, also sucks "life force", which you'd think someone far enough gone to need CPR wouldn't really have to spare.
- Averted humorously in the episode of SpongeBob SquarePants where a large flounder attempts to beat him for no reason in particular. When the flounder suffers a medical crisis, he wakes up in a hospital to learn that his life was saved when SpongeBob performed CPR on him for five hours straight. Regardless, the understanding is that EMS was responsible for his ultimate resurrection.
Spongebob: They said you'd be okay after the first few minutes, but I just wanted to be sure.
- Hilariously parodied on Family Guy when Chivalrous Pervert Glenn Quagmire (during a test to see if some therapy to make him non-perverted worked) suddenly loses control and runs into the security room in a clothing store. There he takes notice of a woman having a heart attack in the changing room. He darts out of the security room and runs to her body and begins what appears to be CPR. However when the woman wakes up, everybody in the store cheers Quagmire for saving her life. Quagmire's response:
Quagmire: What the hell's CPR?
- The trope is seen in a few The Simpsons episodes:
Ned: Now, just breathe into him every three seconds. Make sure you form a tight seal around his mouth!
- "Boy Scoutz 'N the Hood": One scout member gives one to Bart after being choked by his necktie caught in the door.
- "Dog of Death": SLH is revived by CPR during his stomach operation after SLH dreams of going to heaven.
- "It's a Mad, Mad, Mad, Mad, Marge": After Homer faints into the Ark Ice Cream Bowl, Becky, noticing he's not breathing, gives Homer CPR to try to revive him only to have Marge think that she's an upsurper the minute she arrived.
- "Mobile Homer": After being smashed repeatedly on the neck by the garage door and getting suffocated by the spiders, Lisa gives her father CPR with Bart compressing his chest.
- "The Haw-Hawed Couple": After Nelson saves Bart, Skinner gives Bart CPR which lead the children to blurt out a 'gay joke' between them.
- "Stealing First Base": When Bart accidently falls off the roof of the school causing him not to breathe, Nikki rushes to save him with her knowledge of CPR, defying the 'no touch' policy Springfield Elementary has. What follows between is a montage of kissing scenes from classic movies (The Godfather Part II, Lady and the Tramp, From Here to Eternity, Gone With The Wind, Alien 3, etc.), just when Nikki proceeds to breathe air into Bart's lungs, reviving him, saving his life.
- "24 Minutes": After Bart and Willie are saved from drowning, Mrs. Krabappel gives Willie CPR, who would rather die than clean the mess in the gym.
- Subverted in "Pranks and Greens": Andy shows Bart a slideshow of his body of pranks, one of which showing a flight attendant giving him CPR after he faked a heart attack on an international flight.
- "Rome-Old and Juli-Eh": During a montage of Selma and Abe dating, Selma is shown giving him CPR.
- "Midnight RX": Mr. Burns gives Smithers CPR after applying his thyroid medication.
- Hey Arnold!!: Subverted and inverted at the end of "Summer Love" in which Helga gives Arnold CPR after being rescued in a "Babewatch" film shooting, only for her to give him a kiss which surprises Arnold.
- Averted in the Justice League episode "Wild Cards". John, the Green Lantern, isn't breathing, and Hawkgirl gives him CPR. It doesn't work. She then uses her electrified mace as a Magical Defibrillator, which revives him just long enough for her to fly off with him so he can get some real medical attention.
- Averted in Young Justice where CPR fails to revive Artemis, who dies. Considering the character hadn't been drowning at all, but had been stabbed in the stomach, its justified, too. She hadn't actually been wounded anyway. The death and useless CPR were faked, and the onlookers were aliens and therefore didn't realise why it was a stupid treatment.
- Used for humor on Johnny Bravo during a beach episode. After Johnny has nearly drowned, Carl performs mouth-to-mouth on him. Upon reviving and realizing what had happened, Johnny begins screaming and scraping his tongue in disgust.
- In one episode of Jem Minx nearly drowns. Rio somehow revives her by using some subpar CPR tactics.
- In Ever After High Darling resuscitates Apple White from a magic induced coma by blowing air into her mouth. It looks suspiciously more like a kiss than any form of CPR.
- The closest thing to "Clean, Pretty, Reliable" is in drowning victims—successful CPR can revive someone back to consciousness, and people who were quickly recovered have a comparatively high chance of success. Though the high concentration of water makes the vomiting look more "clean", it's still far from pretty, especially if the drowning occured in seawater, which can seriously damage the lungs.
- Even closer is a cardiac arrest due to electric shock. In this case, if performed immediately, CPR may produce the closest possible effect to "miraculous resurrection" (given that only the heart was significantly affected).
- On the day of July 24th 2010 emergency medical dispatcher Chris Solomons had cardiac arrest from a massive heart attack. He was treated with CPR and an AED by his colleagues as seen in this video.
- One thing that is never shown in media depictions of CPR is the damage that the responder does to themselves. Regardless of whether the resuscitation is successful, the responder can expect their trousers (if they are wearing trousers) to be torn through and their knees will be lacerated and bleeding if the floor is even remotely rough. After a protracted session, some first responders have been unable to stand, let alone walk, without assistance.
- In 2012, English football player Fabrice Muamba suffered a cardiac arrest on the pitch. He was treated with CPR for 78 minutes (plus a total of 15 defibrillator shocks, and various drugs in hospital) before his heart resumed beating and given the circumstances was almost perfectly fine.
- Likely part of the miraculous recovery was the fact that medics were on him right after he collapsed, and CPR commenced within a minute. So his brain wasn't without oxygen for long. The cardiologist that worked on him corroborates this idea, saying the reason they continued to work on him so long was because he never degraded from ventricular fibrillation, suggesting the continued CPR was at least keeping him neurologically intact. This is also a textbook example of the fact that CPR itself does not revive someone, as stated at the top.
- This post from a professional EMT describes all the ways CPR can go disgustingly wrong as well as the side effects when it's done properly.
- Sometimes even the TV presentation of CPR can save a life, as proven by this story about an 11-year-old boy who saved a five-year-old girl with CPR he learned from watching NCIS.
- Doing CPR on someone who's collapsed from cyanide poisoning is 100% unreliable, as getting air into their lungs or keeping their blood moving won't do any good: the toxin makes it impossible for tissues to use any oxygen this might deliver to them. Worse yet, if the cyanide was inhaled or ingested orally, attempting mouth-to-mouth without adequate protective barriers could result in toxic cross-contamination, killing the person who's trying to save the victim.
