When talking about Out of Hospital Cardiac Arrest (OHCA) there are really only three things that make a true difference on outcomes (i.e. survival and neurologic function):
- High quality, non-interrupted CPR
- Early defibrillation
- Therapeutic hypothermia
The quality of CPR is often under appreciated and performed incorrectly (too slow and/or not hard enough). With mechanical CPR, chest compressions are delivered uninterrupted and at a predefined depth and rate. In my own practice I have seen these devices being used more and more, but my questions is do these devices impact outcomes?
