What is the procedure used to make air flow into and out of the lungs when breathing has stopped or is irregular?

• A. Cardiopulmonary Resuscitation
• B. AED
• C. Shock
• D. Bandage

Answer: (A)

CPR is the procedure used to move air into and out of the lungs and to keep blood flowing when breathing has stopped or is irregular. It combines ventilation (rescue breaths that inflate the lungs) with chest compressions that circulate oxygen-rich blood to the brain and other vital organs. The breaths directly push air into the lungs, while the compressions maintain circulation so that the oxygen you’ve provided can reach essential tissues. If an AED is available, it should be used as soon as possible to help restore a normal heart rhythm, but the active movement of air is achieved through CPR itself. The other options aren’t procedures for ventilating someone: an AED is a device to shock the heart rhythm, not a ventilation method; a shock is a treatment for certain rhythms, not a breathing aid; a bandage is for bleeding.
