What does CPR stand for?

CPR stands for Cardiopulmonary Resuscitation. This term reflects the two primary functions of the procedure: "cardio," which refers to the heart, and "pulmonary," which relates to the lungs. CPR is a lifesaving technique used in emergencies when someone's heartbeat or breathing has stopped, such as in cases of cardiac arrest.

By performing CPR, individuals can help maintain oxygen-rich blood flow to the brain and other vital organs until advanced medical help arrives. This is crucial because, without immediate intervention, there is a high risk of death or severe brain damage within minutes. The focus of CPR is not only on restoring circulation but also on ensuring effective ventilation to support the person’s respiratory needs.

The other options do not accurately capture the essence or purpose of this vital skill. Terms such as "Critical pressure response," "Controlled physical reflex," and "Cardiac patient relief" do not convey the specific actions of chest compressions and rescue breaths that define CPR. Therefore, understanding that CPR is specifically designed to address both cardiac and respiratory emergencies is essential for recognizing its importance in emergency response situations.
