alt Hacker News> Early CPR (+AED if available) absolutely saves lives. Article is from 2011 by a family med doctor.
You have to provide a denominator to make this statement. 30-day survival for out-of-hospital CPR is 10%, and discharge from the hospital (let alone functional status) is even lower.
CPR is thus a great example of the OP's thesis that doctors refuse certain things based on their poor efficacy.

Did you read what you linked? It's not a study of the effects of cpr, it's a list of facts about cardiac arrest that occurs outside a hospital. It explicitly says cpr is life saving:
>Survival chances decrease by 10% for every minute that immediate CPR and use of an AED is delayed.
