> 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.

100%. CPR initiated within 2 minutes of cardiac arrest increases survival rate by 81%. The fact that CPR is rarely initiated so quickly (and thus survival rates are extremely low), says nothing about the efficacy of CPR. In the best cases where CPR is initiated < 2 mins, and AED shock within < 5mins survival rate can be as high as 50%.

"Early" is load-bearing. Even brief delays, just mere minutes, significantly decrease survival or positive outcomes.

It's important to get people to realize the benefits of early CPR and more people should be trained on how to do it, or else it won't be prompt and the outcomes will be worse. That's what the Red Cross and AHA promulgate to the public, in so many words.

How has CPR (or CPR data) changed since 2011? What type of medicine do you practice?
