10 Things That Happen In Movies That Piss You Off
2. CPR Is Surprisingly Successful & Has No Side Effects
If you take movie CPR at face value, it's an extremely reliable method of bringing someone back from the brink of death without any lasting issues whatsoever.
The overwhelming majority of the time CPR will successfully revive an imperiled heroic character, but in reality CPR that's performed outside of a hospital by an untrained person has as low odds as 1.9% of bringing someone back to life.
Beyond this, CPR is rarely shown to have any adverse side effects at all, such as brain damage caused by being without oxygen for several minutes, or broken ribs as a result of vigorous chest compressions.
For the most part anyone revived through CPR in a movie will cough and gasp for a few moments, maybe spit up some water, and basically be as good as new.
Two of the more memorably outrageous examples include Ethan Hunt (Tom Cruise) reviving after being fatally electrocuted a few minutes earlier in Mission: Impossible III, and a certain character in Netflix's Fear Street movies getting CPR'd back to life after receiving massive stab wounds.
