CPR is an emergency procedure performed to save the life of someone in cardiac arrest. It involves a sequence of activities replicating the heart's pumping and breathing of the lungs to carry oxygen throughout the body.
CPR consists of two main components:
1 cycle of CPR consists of 30 chest compressions followed by 2 rescue breaths.
This procedure replicates the heart's pumping action by administering high-quality chest compressions. With this technique, the blood moves to the body's vital parts.
How to perform chest compressions?
The rescuer will manually breathe air into the victim's lungs, which will simulate the act of inhalation. The air will help oxygenate the blood flowing through the lungs. The air consists mostly of carbon dioxide. But, it also contains all the oxygen that the rescuer's body did not use, constituting almost 17% of the exhaled air. This is enough to sustain the victim's life until the emergency response team arrives.
Hands-only CPR is a method of performing CPR that doesn't require rescue breaths.
