- CPR establishes artificial ventilation and circulation in patients who are not breathing and have no pulse.
Purpose of CPR
- Restore cardiopulmonary functioning
- Prevent irreversible brain damage from anoxia
Indications for CPR
- Cardiac arrest
- Respiratory arrest
- Combination of both
Definition of Cardiac Arrest
- Loss of cardiac function, breathing, and consciousness

- Hypoxia
- Hypotension
- Hypothermia
- Hypoglycemia
- Acidosis (H)
