How long should you check for a pulse in an unresponsive adult?

The appropriate duration for checking a pulse in an unresponsive adult is no more than 10 seconds. This timeframe is critical in emergency situations because prolonged attempts to locate a pulse can delay essential interventions, such as initiating cardiopulmonary resuscitation (CPR) if no pulse is found. Ensuring a timely response increases the chances of a positive outcome, particularly in cases of cardiac arrest.

In practice, if a pulse is not detected within this recommended 10-second window, it is standard protocol to assume that the individual is in cardiac arrest and to proceed with CPR. Recognizing this timeframe as a guideline helps responders act decisively, prioritizing the restoration of circulation and breathing over an extended search for a pulse. This method aligns with the principles of effective emergency response and is taught in CPR courses and guidelines.
