What is the primary goal of CPR?

The primary goal of CPR, or cardiopulmonary resuscitation, is to restore breathing and circulation in a person who has suffered cardiac arrest or is unresponsive due to a medical emergency. When the heart stops beating, blood flow to vital organs, including the brain, ceases, leading to a potential fatal outcome if not promptly addressed. CPR works by manually compressing the chest to help circulate blood and providing rescue breaths to deliver oxygen, thereby increasing the chances of survival until professional medical help can take over.

This option accurately reflects the essential purpose of CPR as a life-saving technique aimed at maintaining blood flow and oxygenation in critical situations. It addresses the immediate physiological needs of the victim, directly impacting their chances of recovery. In contrast, while relieving choking and reviving a person are important, they are specific situations or components of emergency response rather than the overarching aim of CPR itself. Providing emotional support to bystanders is important in a stressful situation but does not relate to the primary physiological goals of administering CPR.
