CPR stands for cardiopulmonary resuscitation, which is an emergency life-saving procedure performed when someones breathing or heartbeat has stopped. It is used in many emergencies, such as an electric shock, heart attack, or drowning. CPR combines rescue breathing and chest compressions to keep oxygen-rich blood flowing until the heartbeat and breathing can be restored. The key steps involved in CPR include:

• Rescue breathing: This provides oxygen to the persons lungs.

• Chest compressions: This keeps oxygen-rich blood flowing until the heartbeat and breathing can be restored.

CPR techniques vary slightly depending on the age or size of the person, including different techniques for adults, children who have reached puberty, children 1 year old until the onset of puberty, and infants (babies less than 1 year of age) . The American Heart Association develops science-based CPR guidelines and is the leader in first aid, CPR, and AED training. High-quality CPR should be performed to increase the chances of survival after cardiac arrest. CPR is a life-saving skill that everyone should learn, and courses are available.
