- In 1960, a physician named Peter Safar used prior research on resuscitation and compression techniques to invent CPR.
- CPR maintains blood circulation and respiration when a person is no longer breathing and has gone into cardiac arrest.
- CPR is most beneficial when performed within four minutes of cardiac arrest and when followed within ten minutes by defibrillation.
- CPR uses a combination of chest compressions and mouth-to-mouth resuscitation techniques performed by either a health care professional or a trained lay person.
- Anyone can become certified in CPR by taking a training course and recertifying on an annual basis.
