Luck of the Titanic

My only criticism is the portrayal of CPR chest compression because it doesn't cause (or almost never causes) a person's heart to resume beating independently. It's a very common misconception that CPR has a higher success rate than it does. It's purpose is to prevent brain injury until help (a defibrillator) arrives. Usually the heart needs an electric jolt to restart. And the success rate of CPR with chest compression, breathing into the person, and using the defibrillator is sadly much lower than as shown in media

But I don't hold it against the author or editors, because it's such a common misconception that I only learned it by searching “CPR success rate” in a search engine on a whim.
