CPR can be life-saving first aid and increases the person’s chances of survival if started soon after the heart has stopped beating. If no CPR is performed, it only takes three to four minutes for the person to become brain dead due to a lack of oxygen.
By performing CPR, you circulate the blood so it can provide oxygen to the body, and the brain and other organs stay alive while you wait for the ambulance. There is usually enough oxygen still in the blood to keep the brain and other organs alive for a number of minutes, but it is not circulating unless someone does CPR. CPR does not guarantee that the person will survive, but it does give that person a chance when otherwise there would have been none.
If you are not sure whether a person is in cardiac arrest or not, you should start CPR. If a person does not require CPR, they will probably respond to your attempts. By performing CPR, you are unlikely to cause any harm to the person if they are not actually in cardiac arrest.
