How soon after recognizing cardiac arrest should you begin chest compressions?

Beginning chest compressions as soon as possible after recognizing cardiac arrest is critical for the survival of the patient. The correct answer emphasizes that chest compressions should be initiated within 10 seconds of identifying that breathing has stopped and the heart is no longer pumping effectively.

This time frame is vital because the brain and other organs begin to suffer irreversible damage within minutes of oxygen deprivation. By acting quickly, health care providers can help maintain blood flow to vital organs until advanced medical help is available. Starting compressions within 10 seconds ensures that the victim receives immediate care, which can significantly improve their chances of survival and reduce the likelihood of permanent damage due to lack of oxygen.

Options suggesting longer delays before starting compressions can lead to detrimental outcomes, as the longer a person is in cardiac arrest without circulation, the higher the risk of morbidity and mortality. Therefore, initiating chest compressions quickly is a critical component of effective cardiopulmonary resuscitation (CPR) protocols.
