CPR, or cardiopulmonary resuscitation, is an important life-and-death skill. This procedure aims to control blood flow after a heart attack. Without CPR or other procedures, a person could die within eight to 10 minutes of a heart attack.

When a person has a heart attack, the person's heart stops, so blood doesn't flow to the brain and other internal organs. It is important that the brain and heart continue to receive blood and oxygen. Impaired blood flow, even within 3-4 minutes, can damage the brain.

The goal of CPR is to ensure that the body's organs are continuously, if at a minimum, supplied with blood and oxygen to avoid permanent damage.

Rapid implementation of CPR can increase a victim's chance of survival by up to 50%. Of course, CPR does not cure the cause of the attack, but gives the victim the option of receiving procedures such as cardiac defibrillation or surgery.

Remember, CPR is not limited to situations such as a heart attack or drowning. Other situations that may require CPR intervention include suffocation, overdose, electric shock, and severe allergic reactions.

Traditional CPR

This method of CPR uses chest compressions along with rescue breaths. Chest compressions are performed at 100 beats per minute. One piece of advice the American Heart Association gives students is to take a BeeGees compression punch to achieve the correct compression level.

Hand CPR only

They are firm and rapid continuous chest compressions, but without mouth-to-mouth resuscitation.
