A heart attack occurs when the blood flow to the heart is blocked. This can be through heart disease and narrowing of the arteries and it can also be as a result of a blood clot. In most cases these people will be conscious and will not need CPR. When a cardiac arrest occurs the individual will lose consciousness and their heart will stop beating. When this occurs it is a race to get their heart beating once again. This is where CPR comes into play.

The chest compressions that are used in CPR mimic how the heart works and it pumps blood through the heart and out to the vital organs. This will give time for paramedics to arrive, where they can use a defibrillator to restart the individual’s heart. The quicker a person gets help, the more likely they are to go on and make a recovery. In some cases the use of CPR can triple a person’s chances of survival.
