Cardiopulmonary resuscitation (CPR) is a set of medical procedures that attempt to restart the heartbeat and breathing of a person who has no heartbeat and has stopped breathing. Such procedures may include the following:
- Chest compressions to mimic the heart’s functions and cause blood to circulate
- Inserting an airway into the mouth and throat, or inserting a tube into the windpipe
- Ventilating artificially, through mouth-to-mouth or other mechanically assisted breathing
- Using drugs and/or electric shock (defibrillation) to stimulate the heart
- CPR can be life-saving in certain cases for otherwise healthy people but is much less effective when a person is very frail/elderly or has a serious chronic illness.
