“10 minutes is a long time doing proper chest compressions.”
Exactly. Thank you.
What I saw when we brought CPR’s into the hospital was people there who would use about about half of their upper body weight and half bent arms which they would try to straighten on each compression.
That is very tiring. Keeping your elbows locked and using the weight of your upper body and a good strong core makes 10 minutes a good workout. Been there done that over a career dating back to the Reagan administration.
