I would not expect a medical team or an AED to be inside the track but surrounding it yes. And doctors out there tell me, but aren't chest compressions often done before AED in a lot of situations?
Chest compressions should always be started IMMEDIATELY upon realizing the pulse is absent. Every second counts because if the heart is not pumping, the brain is not perfusing with blood and the clock is ticking for brain damage/death.
An AED cannot always be used. Contrary to popular belief, an AED cannot be used if the patient's heart is asystolic (heart has stopped). An AED CANNOT restart a stopped heart. The AED can only be used when there is an arrhythmia, either V-tach or V-fib. In both cases the heart is beating but it is so irregular that the pumping action is ineffective to move blood. The AED will send a shock to temporarily stop the heart and allow it to restart, hopefully with a proper rhythm.
The nice thing is the machine does all the work; even someone with no medical training can use one. There is a picture showing where the pads go and once they are on, just press start and the AED will analyze the rhythm and tell the user if the rhythm detected is shockable or not. If it is, it will tell you to shock the patient. If not, continue with CPR since the machine will not help.
