--1--Is there any risk that CPR administered in a wrong situation will cause serious harm ? In other words, if it is not really a case of cardiac arrest, and is wrongly thought to be so, and if CPR is administered to the (unconscious) person, would it cause any serious harm ?
--2--If CPR is administered wrongly (for example the pushes are too deep, or too frequent), will it cause it any serious harm ?
