Artificial Respiration and Cardiopulmonary resuscitation (CPR)

Respiratory failure is a critical concern for a first aider. There are many different techniques for giving artificial respiration. The most widely taught and accepted technique goes by a variety of names, such as "mouth to mouth", "rescue breathing", and "direct". Using this technique, air is expelled from the rescuers lungs directly into the victim's mouth. Assuming a tight air seal, the air is forced into the victim's lungs, and the rescuer watches to see the victim's chest rise with each breath. This technique is direct, and the effectiveness can be visually measured by the rescuer. If the chest of the victim does not rise, then the mouth and throat should be checked for obstructions before rescue breathing is continued.
Cardiopulmonary resuscitation (CPR) is a combination of rescue breathing and chest compressions delivered to victims thought to be in cardiac arrest. When cardiac arrest occurs, the heart stops pumping blood. CPR can support a small amount of blood flow to the heart and brain to “buy time” until normal heart function is restored.
