Can you restart the heart with CPR? - Dr. Raghavendra Chikkatur

One may not be able to restart the heart with just CPR alone. The purpose of CPR is to keep the oxygenated blood supply to the brain and to the other vital organs including the heart. It is very important to initiate the CPR within 3 – 5 minutes; otherwise he brain function will not be normal if resuscitated at later stage. A person may die within 8 – 10 minutes if cardiopulmonary resuscitation is not begun. The main purpose of the CPR is to start some blood supply to the brain to preserve the brain function until the help arrives or the other help by medics or paramedics taken to restore the circulation.
