What benefit does quality CPR provide during cardiac arrest?

Quality CPR plays a critical role during cardiac arrest, primarily because it improves the chances of survival and neurological outcomes for the patient. When the heart stops beating effectively, there is a significant risk of brain and organ damage due to a lack of oxygenated blood. High-quality chest compressions help maintain blood flow to vital organs, particularly the brain and heart, during this critical period.

Effective CPR can double or triple a person's chance of survival after cardiac arrest. The technique involves proper rate and depth of compressions, ensuring adequate circulation, which can help to prevent brain death and maximize the chances of a favorable neurological outcome if the patient is successfully revived. This is why quality CPR is emphasized in resuscitation guidelines as a foundational intervention until advanced life support measures, such as defibrillation or medication administration, can be initiated.

While other options might have relevance in specific scenarios, the primary and documented benefit of high-quality CPR is the significant improvement in survival and neurological function.
