What is the maximum time you should feel for a pulse before starting CPR on an adult?

The correct response indicates that you should assess for a pulse for at least 10 seconds before deciding to start CPR on an adult. This timeframe is important because it allows the responder to make a thorough assessment of circulation without delaying critical emergency interventions. If there is any doubt about the presence of a pulse, after 10 seconds of careful checking, it is more prudent to initiate CPR, as this action can be lifesaving in a situation where the adult may be experiencing cardiac arrest.

Taking more than 10 seconds—such as 15 or 30—could unnecessarily delay the start of CPR, which is crucial in maintaining blood flow to the heart and brain. Starting CPR without hesitation when no pulse is detected helps increase the chance of survival and limits brain damage due to lack of oxygen. Therefore, aiming for a balance of quick assessment and prompt action is key to effective response in emergency situations.
