Which pulse site is the preferred site for checking the pulse in an adult during CPR?

The carotid pulse is the preferred site for checking the pulse in an adult during CPR because it is easily accessible and provides a reliable indicator of circulation in an emergency situation. The carotid arteries are located in the neck, allowing for quick assessment while maintaining the airway. In a scenario where CPR is necessary, time is of the essence, and having an effective way to assess a pulse is crucial.

Additionally, the carotid pulse is typically the last pulse to disappear in cardiac arrest, making it a more reliable indicator compared to other sites. The radial pulse, while commonly used in non-emergency situations, may be challenging to palpate if circulation is compromised. The femoral pulse, while also a valid option, is less convenient to assess quickly, especially in an emergency where maintaining the flow of care is critical. The popliteal pulse, found behind the knee, is even less commonly used in emergencies due to its deeper location and the difficulty in palpation compared to the carotid pulse. Overall, the carotid pulse serves as the most practical and effective site for pulse checking during CPR in adults.
