How long should you check for responsiveness when administering first aid?

When administering first aid, particularly in the context of checking for responsiveness in an unconscious person, it's critical to assess responsiveness in a timely manner to ensure the person's condition is determined with adequate urgency. The recommended duration for checking for responsiveness is about 10 seconds. This timeframe allows a rescuer to adequately evaluate whether the person is responsive by calling out to them and lightly shaking their shoulder.

A response during this interval signifies that the individual is likely conscious and aware, which can guide subsequent first aid actions—whether to monitor them, assist them, or call for more advanced medical help, depending on their condition. If a person does not respond within this critical window, it suggests a more severe condition that may require immediate intervention, such as calling emergency services or starting CPR if necessary.

The length of time is essential; a shorter check, such as 5 seconds, may not provide sufficient scrutiny to determine responsiveness accurately. Extended checks, like 30 seconds or “until help arrives,” could delay necessary actions, which could be detrimental in emergencies where time is of the essence.
