What pulse should be checked for an unresponsive adult?

In an emergency situation involving an unresponsive adult, the carotid pulse is the preferred pulse to check. This is primarily because the carotid artery, located on either side of the neck, is easily accessible and provides a strong and reliable indicator of heart activity. Checking the carotid pulse is vital for assessing circulation, especially when the individual is unresponsive, as it allows for quick evaluation of whether the heart is beating effectively.

Other pulse points, such as the radial, brachial, and popliteal pulses, are less ideal in this scenario. The radial pulse, found on the wrist, can be difficult to palpate if blood circulation is compromised. The brachial pulse, located in the arm, is typically used in infants or younger children. The popliteal pulse, found behind the knee, is also less accessible and not practical for rapid assessment in an adult who is unresponsive. Thus, the carotid pulse is the most effective choice for assessing blood flow and determining the necessary interventions in such emergency situations.
