If defibrillation is so important, why should I do CPR?

cpr or aed

A person has just collapsed and they are not breathing. You see an AED on the wall near the victim, but you don’t know whether to begin with CPR or place the AED on the victim’s chest. It is true that CPR provides some circulation of oxygen-rich blood to the victim’s heart and brain, and this circulation does indeed delay both brain death and the death of heart muscle. However, if you have an AED you want to apply the pads to the victim and turn it on immediately! You can put your trust in an AED to tell you when to provide CPR or shock the victim.

CPR is thought to make the heart more likely to respond to defibrillation. If the bystanders at the scene are able to provide CPR, the victim’s chances of survival will be significantly increased. The longer the body goes without circulation, the lower the chance of survival. By performing CPR, you are able to help the person’s blood keep circulating until an ambulance arrives and more advanced tools can be used. We know that the chance of surviving a sudden cardiac arrest increases significantly, by more than double, when CPR is started early. However, CPR is essentially used to “buy time” for a victim until the EMS arrive with a defibrillator. You will always want to get the victim hooked up to the AED as soon as possible and follow the directions given by voice prompts.
