Technically, defibrillation is not part of CPR. CPR consists of chest compressions and artificial ventilations (also called "rescue breathing"). The point of CPR is to keep oxygen circulating through the body. CPR can resuscitate a person whose heart and lungs have stopped working, but it unlikely to help in situations where the heart's electrical patterns have been disrupted. That's where defibrillation (and drugs) comes in. Only a patient with a 'shockable' electrical pattern -- generally "ventricular fibrillations" (VF) or "ventricular tachycardia" (VTach) are the only shockable rhythms -- can be helped with a defibrillator.
So, of course defibrillator paddles could not perform CPR by themselves, nor could someone perform CPR with them.
I knew you all wanted to know this.
(Dr. Pedantic should have been the one to mention this, but he was taking a nap and I didn't want to disturb him.)
