And now for some RealLife UsefulNotes about CPR.

!!!'''First off, if someone near you is not breathing at this moment, call emergency services and let them help you. If your first reaction when faced with a medical emergency is to go to TV Tropes, well, [[WhatTheHellHero you're probably beyond help.]]'''

This is a {{Useful Note|s}}. It is designed to help readers understand how things work in real life so that you can compare it to how it works in fiction. It's a way for you to [[ShownTheirWork do the research]] rather than actually apply it to your RealLife. UsefulNotes are [[ImADoctorNotAPlaceholder written by Tropers, not medical professionals]] and carry no guarantee of accuracy (or indeed, [[NonindicativeName usefulness]]) for your situation. We don't particularly want you [[TVTropesWillRuinYourLife ruining someone else's life]].

Really, if you find yourself in a situation where someone needs help, seriously, [[CaptainObvious call emergency services in your jurisdiction]]. It's
* 9-1-1 in North America
* 1-1-2 in the European Union
* 9-9-9 in the British Commonwealth and many of its former constituent nations.
These numbers are the most common. Most mobile phones will help you by directing you to local emergency services if you call any of these common numbers. You usually don't even have to unlock your phone to call emergency services; modern smartphones may even have it as a separate function. Operators can instruct you on the phone. Time is of the essence.


CPR, AED and other First Aid training is highly desireable, especially in certain fields of employment. If you are interested, certification courses are widespread. A good place to look is your local [[UsefulNotes/TheRedCross Red Cross]]. [[note]]Any national affiliate of the International Red Cross and Red Cresent Movement, depending on if Christianity or Islam is the predominant religion of the country in question. In Israel, it's Magen David Adom, or Red Star of David, which is used in conjunction with the secular Red Crystal logo.[[/note]]

Proper execution of CPR is vital, which is why formal training is important.[[note]]Frequent re-training is also important because changes to procedure happen all the time. For example, in recent years, mouth-to-mouth is no longer recommended in most non-drowning cases.[[/note]] If done wrong, not only could it be ineffective, but it could damage the rib cage in a fatal manner. Proper execution could still break ribs; this is alright, and some physicians suggest it may even be necessary[[note]]Considering death is the likely alternative.[[/note]]. Improper execution could snap off the xyphoid process at the bottom of the sternum and damage the heart itself, rendering CPR pointless.

Don't confuse it with the Heimlich maneuver, used to expel objects blocking a person's throat. CPR is for dealing with a stopped or very slowed heart, an entirely different emergency.
