What describes CPR?

CPR, which stands for cardiopulmonary resuscitation, is a life-saving technique that is essential in emergencies where someone's breathing or heartbeat has stopped, typically in cardiac arrest situations. The primary purpose of CPR is to maintain blood flow to the brain and other vital organs until professional medical help arrives. This involves specific procedures, including chest compressions and rescue breaths, aimed at restoring normal heart function and ensuring oxygen delivery to the body's tissues.

In contrast, the other choices do not accurately reflect what CPR is. Measuring temperatures pertains to assessing body heat and is not related to emergency medical procedures. Exercise for heart health refers to physical activities that can improve cardiovascular fitness but does not involve the immediate response required in a life-threatening scenario. Providing physical therapy focuses on rehabilitating patients to improve their physical abilities and does not include the emergency intervention techniques used in CPR. Therefore, describing CPR as a set of medical procedures for treating cardiac emergencies is accurate and highlights its critical role in emergency medicine.
