Cpr first aid:


CPR (treatment): Another name for Cardiopulmonary resuscitation.
CPR (treatment): Emergency resuscitation of both heartbeat and breathing
The interchangeably by most people the term cardiac arrest and the heart attack is not the same. cardiac arrest is the stoppage of the heart where as heart attack can result in cardiac arrest, but not all heart attacks do so (e.g. it may cause chest pain instead). Both cardiac arrest and heart attack need emergency immediate professional medical attention.

How does cpr works:
The air we breathe in travels to our lungs where oxygen is picked up by our blood and then pumped by the heart to our tissue and organs. When a person experiences cardiac arrest - whether due to heart failure in adults and the elderly or an injury such as near drowning, electrocution or severe trauma in a child - the heart goes from a normal beat to an arrhythmic pattern called ventricular fibrillation, and eventually ceases to beat altogether. It prevents oxygen from circulating throughout the body, rapidly killing cells and tissue. In essence, Cardio (heart) Pulmonary (lung) Resuscitation (revive, revitalize) serves as an artificial heartbeat and an artificial respirator. Before you start any rescue efforts, you must remember to check the victim for responsiveness.

Cardiopulmonary resuscitation (CPR) is a lifesaving technique useful in many emergencies, including heart attack or near drowning, in which someone's breathing or heartbeat has stopped. CPR involves a combination of mouth-to-mouth rescue breathing and chest compression that keeps oxygenated blood flowing to the brain and other vital organs until the more definitive medical treatment can restore a normal heart rhythm. Remember ABCS : airway,breathing,circulation.

Airway: clean the airway
Put the person on his or her back on firm surface.
Kneel next to the person's neck and shoulder.
Open the person's airway by using the head tilt-chin lift. Then with other hand gently lift the chin forward to open the airway.
Do not consider gasping to be normal breathing. If the person is not breathing properly then begin mouth to mouth breathing.

Breathing: breathe for the person
Rescue breathing can be mouth to mouth breathing or mouth to nose breathing if the mouth is injured.
