When you do CPR, you are performing the work that the heart can no longer do, due to Cardiac Arrest (heart stoppage). Every time the chest is compressed, this forces the blood in the heart round the body, and this keeps blood and oxygen flowing to all parts of the body, if not some.

However, CPR and Mouth to mouth alone are not good enough (even though it is better than no action at all). A machine called a defibulator (AED) is required. This machine sends a shock, that will hopefully make the heart beat again.

What about failed CPR?

As a first responder, we always perform CPR if the situation calls for it. We may never know if the CPR we performed was able to save the life or not. Depending on the medical emergency, there may be no chance for recovery. CPR will not always save a life, so if it is not able to it is OK. We will always perform CPR if the situation warrants and if it fails it is OK, We did our part to give the person the chance to be saved by our prompt response.
