This is a field where a surprising amount of progress is being made. People still tend to assume that CPR is mostly a token effort so bystanders feel like they're doing something. In reality, high quality CPR + rapid access to an AED can give just about any heart a fighting chance at beating again (assuming the underlying problem is transient or easily treatable... if your LAD cardiac artery is 100% occluded and half…
No offense to your passion, but I thought that CPR can be quite dangerous and ineffective. Don't many doctors wear DNR tags because of this? The wikipedia article [1] has some information on this. The survival rate is something like 4% even though immediate recovery is around 40% (they survive long enough to get to the hospital, where they die due to the underlying condition). Meanwhile, the person has to suffer with…
If CPR is ineffective, the result is death. Dangerous? Not particularly.
Most people wearing DNR tags (aside: even a DNR tattoo on the chest is not considered legally binding against "heroic measures", unless signed by a physician) do so to provide some measure of what the patient might want (due to life expectancy, illness, etc).
Survival rate to discharge is HIGHLY dependant on many, many variables - I mention elsewhere that in certain parts of the country, due to concerted education and well managed/funded EMS systems, survival rates can approach 50% to discharge. You are right, though, successful CPR isn't going to negate the underlying cardiac condition.
If CPR buys a patient a year to five years, the pain of broken ribs is probably fairly minor in the grand scheme of things.
There are, as mentioned, a whole host of advances. My home EMS system does some fairly deep analysis of all CPR attempts and works to revise protocols, including what drugs to administer, through to 'continuing compression through defib shock' (studies done on medical students showing it to be a viable possibility).
Ultimately, education is the key - the ability to get skilled compressions more quickly on the chest, continuing to perfuse the brain and other organs has a huge impact in survivability, as well as damage done.
