That is why one needs to start giving CPR ASAP.
If CPR is delivered correctly, it provides both coronary and cerebral perfusion.
It is unfortunate that most people don't understand that CPR and AED work most effectively together - CPR to keep the oxygenated blood flowing and AED to shock the heart back to a normal sinus rhythm.
