What is the main location for checking the radial pulse?

The radial pulse is primarily checked at the wrist, specifically at the radial artery, which runs along the thumb side of the forearm and wrist. To locate the radial pulse, a person places their fingers just below the base of the thumb on the wrist and feels for the pulsation of the artery. This location is favored due to its accessibility and the ease with which one can feel the pulse, making it a standard practice in various medical and first aid situations for assessing heart rate and rhythm. Resting hands on the wrist allows for a quick and effective assessment, which is particularly useful in emergencies or routine checks.
