Which pulse is checked in an unresponsive adult?

In an unresponsive adult, the carotid pulse is the most appropriate to check because it is centrally located and typically easier to assess in a person who is not responding. The carotid arteries are situated on either side of the neck and provide a strong pulse that is critical for determining circulation. This is especially important in emergency situations where quick assessment of the patient's condition is necessary.

The carotid pulse is more reliable than peripheral pulses, such as the radial or dorsalis pedis pulse, which might be weak or difficult to palpate if the patient is in shock or has a poor perfusion status. Checking the brachial pulse is also an option, but it is generally more commonly used in infants or in situations where access to the carotid is difficult. Thus, for an unresponsive adult, the carotid pulse is the best choice for evaluating circulation effectively and promptly.
