MEDICAL PHYSIOLOGY

Detailed explanation-1: -Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.

Detailed explanation-2: -CPR helps keep the blood circulating and delivers oxygen to the body until specialist treatment is available. There is usually enough oxygen still in the blood to keep the brain and other organs alive supported for a few minutes, but it is not circulating unless someone does CPR.

Detailed explanation-3: -Give the first rescue breath-lasting one second-and watch to see if the chest rises. If the chest rises, give a second breath. If the chest doesn’t rise, repeat the head-tilt, chin-lift maneuver and then give a second breath. Thirty chest compressions followed by two rescue breaths is considered one cycle.

Detailed explanation-4: -For an unconscious adult, CPR is initiated as follows: Give 30 chest compressions. Perform the head-tilt chin-lift maneuver to open the airway and determine if the patient is breathing. Before beginning ventilations, look in the patient’s mouth for a foreign body blocking the airway.
