Which pulse site is commonly checked in adults during CPR?

The carotid pulse in the neck is the most commonly checked pulse site in adults during CPR due to its accessibility and reliability. When performing CPR, it is crucial to quickly assess whether the heart is still beating. The carotid artery is located close to the surface of the skin and provides a strong pulse that can be easily felt, making it ideal for determining if effective circulation is present.

Checking the carotid pulse allows a responder to establish whether it is necessary to initiate CPR. If there is no pulse felt within 10 seconds, immediate CPR should begin. This pulse check is a vital step before starting chest compressions, as it provides the responder with important information about the patient's condition.

The other pulse sites, although they can be used in various medical assessments, are not as effective or practical during the critical situation of cardiac arrest in adults. The radial pulse may not be strong enough to detect in an unresponsive person, and the femoral pulse is more difficult to assess quickly. The brachial pulse is usually used in infants or young children rather than adults, making the carotid pulse the most appropriate choice in this scenario.
