Answer :
Answer: It is known as Cardiopulmonary Resuscitation (CPR)
Explanation: CPR is an emergency technique used on someone that his or her heart has stopped working or someone that has stopped breathing as a result of cardiac arrest or near-drowning. It is usually performed in an effort to manually preserve intact brain function by maintaining adequate perfusion of tissue until there is a definitive treatment procedure for the victim.
The artificial respiration is usually through mouth-to-mouth breathing/ventilation.
The manual external cardiac compression involves pushing hard and fast in the centre of the chest.
