Answer:
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:
- Basic CPR involves rescue breathing and chest compressions. It is a first aid technique that can be used until the patient can be taken to a hospital.
- Advanced CPR employs the use of drugs and instruments, such as a defibrillator monitor. This procedure is performed by qualified personnel, in mobile units or in hospital emergency rooms.
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.
