Four out of five elderly people given CPR end up dying within days. Many of them with prolonged and intense suffering due to CPR prolonging the inevitable.
We certainly need more thought about end-of-life care, living wills, and do-not-resuscitate orders. But CPR is not the only intervention affected by that.
And in some cases CPR is given when it's not warranted, breaking ribs, collapsing lungs or otherwise causing serious and sometimes fatal damage.
Sometimes, yes, but more rarely than you might think.
If I keel over, please don't resuscitate unless there is at least a 50% chance of long-term success, and less than a 50% chance of causing long-term damage.
Dude, unless you're already in the hospital, whoever sees you go down or trips over your unconscious body does not have your medical history, nor can they predict your course of treatment.
