How quickly should you start compressions after recognizing cardiac arrest?

The best practice according to current guidelines for cardiopulmonary resuscitation (CPR) emphasizes the urgency of initiating chest compressions as soon as cardiac arrest is recognized. Starting compressions within 10 seconds ensures that blood circulation is maintained to vital organs, especially the heart and brain, thereby increasing the likelihood of survival and favorable outcomes.

The rationale for this time frame is based on the understanding that effective and timely compressions can significantly improve the chances of resuscitation. Delays in starting compressions can lead to irreversible brain damage and increases the chances of morbidity and mortality in the patient. Therefore, acting quickly—ideally within 10 seconds—aligns with the critical need for prompt and effective intervention in emergency situations involving cardiac arrest.

This guideline supports the fundamental idea of the "Chain of Survival," which outlines the sequence of actions that can maximize the chances of survival. The quicker you initiate CPR, the better the chances of restoring a normal heartbeat and stabilizing the patient.
