We've had folks in our ICU with busted ribs, punctured lungs and even a pierced heart from CPR - but they all made it!
Without CPR they would be dead for sure.
So gjimene2 is correct - if ya wanna survive, a bit of pain for a while is nothing.
But it does feel awful when you know you've busted something and you also know you've gotta keep compressing...
But it feels
real good if they survive and you get to see them go home!
