What is the expected outcome of correctly performing chest compressions during CPR?

The correct answer focuses on the primary purpose of chest compressions during cardiopulmonary resuscitation (CPR), which is to circulate blood to vital organs. When a person goes into cardiac arrest, their heart stops beating effectively, meaning that blood is no longer being pumped throughout the body. By administering chest compressions, rescuers create artificial circulation, which helps to deliver oxygenated blood to essential organs such as the brain and heart. This is crucial because it buys time for emergency medical services to arrive and may prevent irreversible damage to these organs.

The other choices, while they may relate to different aspects of medical training, do not address the main function of chest compressions. Maintaining control of airflow is relevant to rescue breaths, while proper spine alignment has more to do with spinal injury management than with the CPR technique itself. Balancing electrolytes, while important in many medical scenarios, does not directly pertain to the immediate actions taken during CPR with chest compressions.
