The correct word for 'C' in C.A.B. is B. Circulation (Compressions), referring to the chest compressions performed during CPR to maintain blood flow, particularly to the brain, during a cardiac arrest.
The correct word for 'C' in C.A.B. as it relates to emergency medical care is B. Circulation (Compressions). C.A.B. is an acronym that stands for Compressions, Airway, and Breathing, which are the steps to be performed when administering cardiopulmonary resuscitation (CPR). In the context of CPR, circulation refers to chest compressions that are performed to manually pump blood through the heart to the rest of the body, primarily to maintain blood flow to the brain and avoid irreversible damage due to lack of oxygen.
CPR is a life-saving technique used in emergencies such as cardiac arrest, where the heart stops beating effectively. It involves applying pressure on the sternum, between the lines at T4 and T9, to squeeze blood out of the heart and into circulation. This continues until spontaneous heart rhythm is restored or the patient is declared dead by a healthcare professional. Compressions should be at least 5 cm deep and at a rate of 100 compressions per minute, which coincidentally matches the beat of the song 'Staying Alive' by the Bee Gees.
