What is the main goal of CPR in cases of cardiac arrest?

The primary goal of CPR, or cardiopulmonary resuscitation, during a cardiac arrest is to maintain blood flow to the vital organs, particularly the brain and heart. When the heart stops beating effectively, blood circulation ceases, depriving these organs of oxygen and nutrients they need to function. By performing CPR, which involves chest compressions and, if trained, rescue breaths, the rescuer can help artificially circulate blood. This circulation is critical as it keeps the brain and heart viable until advanced medical assistance arrives or normal heart function can be restored.

Reviving the patient immediately is often an expectation or hope, but the reality is that CPR is a process aimed at sustaining life functions rather than an immediate revival. Stopping the heart from beating does not apply, as CPR aims to restore normal heart rhythms and functions, not inhibit them. Preparing the victim for surgery is also not a part of CPR's immediate goals during a cardiac emergency; instead, the focus is on resuscitation efforts and stabilizing the patient until further medical intervention can occur.
