* AcceptableTargets: Henrik Hanssen is used as a device to show the Scandinavians in a particular way, used for RuleOfFunny purposes.
* {{Anvilicious}}: Well, that's how some people see it...
* AnvilsThatNeededToBeDropped: Too numerous to mention.
* BigLippedAlligatorMoment: Since late 2008, this show has started using them. Too many to mention.
* EnsembleDarkhorse: Marie-Claire Carter, an [[{{Oireland}} Irish-accented character]]; a recurring character from 2009 to 2012, she was promoted to full regular status in 2013.
** Also, the appearance of Kate, played by [[EmbarrassingFirstName Stirling]] Gallacher.
** The two recurring anaesthetists, Keith Greene and Paul Rose.
* MagnificentBastard: Cardio Thoracic surgeon Anton Meyer (George Irving) in the first few series. In the first episode he told a patient that if he (the patient) ever smoked again he (Meyer) would personally undo everything he had done on the operating table.
* MemeticMutation: The female nurses' outfits (i.e. the scrubs worn by the EnsembleDarkhorse extras and Jac Naylor, Mary-Claire Carter and Donna Jackson. Also Jac Naylor's non-medical outfits too.). ''Certainly'' popular with students, making the sexy nurse outfit (considered cliched these days) somewhat [[DiscreditedTrope no longer fashionable or trendy]].
* NightmareFuel: For a supposedly pre-watershed show, this can contain heavy doses of it.
** This show has tried to emulate Creator/StevenMoffat, but hasn't come close to it though. Not that it fails at being scary (certainly for children anyway).
** The ChristmasEpisode of the show often contains doses of this, even more so than ''Series/DoctorWho'', giving that show a run for its money in the festive season.
** Much of the episodes produced by Jane Wallbank fall into this territory.
* PeripheryDemographic: Popular with high-school age, and college-age students, despite being aimed at adults.
* SendingStuffToSaveTheShow: Inverted. More like {{Fandom}} requests to give background characters into [[CharacterisationMarchesOn proper characters]].
** This isn't that uncommon in the United Kingdom, well, for background characters to be popular.
