> 'correctly done' chest compressions are extremely violent. For a good visual of this take a look at a LUCAS machine in operation [1]. I'm a (retained) firefighter and have seen paramedics deploy a LUCAS - it's quite a thing to behold. > If there's an AED around to use instead that would be FAR more preferable. Sadly AED's aren't always appropriate. They need a "shockable rhythm" - that is if your heart is in ventricular tachycardia or ventricular fibrillation [2]. One interesting fact I recall reading (source long forgotten ...) is that collapsed women are less likely to be helped with AED's by passers by. This is because they feel uncomfortable uncovering the chest to apply the AED pads.
