Which pulse check site is most suitable for an unresponsive adult?

In the context of an unresponsive adult, checking for a pulse at the carotid artery is the most suitable option. The carotid artery, located on each side of the neck, is easily accessible and provides a strong pulse, which makes it ideal for assessing circulation in an emergency situation. When an individual is unresponsive, rapid assessment of their pulse is critical, and the carotid artery allows healthcare providers to quickly determine whether the heart is still beating and assess the effectiveness of circulation.

Additionally, the carotid pulse is less likely to be affected by peripheral circulation issues that can occur in cases of shock, where pulse checks at the radial artery or other peripheral sites might not be reliable. In emergencies, speed and efficiency are priorities, and using the carotid artery provides direct insight into the person's cardiac status.
