cardiopulmonary resuscitation

Show Summary Details

Quick Reference

(CPR) an emergency procedure for life support, consisting of artificial respiration and manual external cardiac massage. It is used in cases of cardiac arrest or apparent sudden death resulting from electric shock, drowning, respiratory arrest, or other causes, to establish effective circulation and ventilation in order to prevent irreversible brain damage. External cardiac massage compresses the heart, forcing blood into the systemic and pulmonary circulation; venous blood refills the heart when the compression is released. Mouth-to-mouth resuscitation or a mechanical form of ventilation oxygenates the blood being pumped through the circulatory system.
