What is the primary role of the rescuer when performing CPR?

The primary role of the rescuer when performing CPR is to maintain blood flow and oxygenation to vital organs. This is crucial because when a person experiences cardiac arrest, their heart is not effectively pumping blood to the brain, heart, and other essential organs. Immediate chest compressions help to circulate the remaining blood, providing oxygen to the brain and ensuring that the body's tissues do not suffer irreversible damage. The emphasis on maintaining blood flow underscores the urgency of CPR, as every moment without proper circulation increases the risk of death or severe brain injury.

While stabilizing the patient's spine, calling for emergency services, and checking for responsiveness are important aspects of overall patient care, they are not the primary goal during the immediate action of CPR. The main focus during CPR remains on compressions, as this directly impacts the chances of survival and recovery for the individual in cardiac arrest.
