Cardiopulmonary resuscitation is a first aid technique for individuals in cardiac arrest that involves . A.
a defibrillator and rescue breathing
B.
rescue breathing and chest compressions
C.
a defibrillator and chest compressions
D.
chest compressions and adrenaline injections

Cardiopulmonary resuscitation involves rescue breathing and chest compression (option B).

Explanation:

Cardiopulmonary resuscitation (CPR) is a procedure used in cases of cardiorespiratory dysfunction or arrest, so it is necessary to ensure proper breathing and cardiovascular function.

There are two levels of CPR:

First aid in case of cardiac arrest depends on both respiratory resuscitation —rescue breathing— and chest compression.

    The other options are not valid, because they all involve advanced CPR techniques and not first aid, and the options a defibrillator and chest compressions (C) and defibrillator and chest compressions (D) leave out breathing rescue.
