An automated medical device which provides chest compressions during CPR. It is used for patients that are in cardiac arrest (the heart has stopped). The device is typically wraps around the chest and is attached to a plastic board underneath the patient. The "geezer squeezer" makes CPR more effective and easier for ambulance crews because it reduces fatigue associated with doing chest compressions. Also known as a "Thumper".
Did you see the patient that EMS just brought into the hospital? They had the "geezer squeezer" on him. I hope he makes it.
