The main focus during adult CPR is to circulate oxygen-rich blood to the brain and other vital organs. This is essential because, during cardiac arrest, the heart is unable to pump blood effectively, which can lead to a rapid decline in brain function and other vital organ performance due to lack of oxygen. By performing high-quality chest compressions, the rescuer can help artificially circulate blood throughout the body, which is crucial for preventing permanent damage to the brain and other organs. The goal of CPR is to maintain this circulation until emergency medical services (EMS) arrive and advanced care can be provided.

While maintaining airway patency is important and can be part of the CPR sequence, the primary emphasis during the compressions phase is on effective blood circulation. Comforting the patient is not a priority in a life-threatening situation, and monitoring heart rate, although it may be relevant in a clinical setting, is not a focus during the immediate execution of CPR.
