Which pulse site is commonly used to assess circulation in an adult?

The radial pulse is commonly used to assess circulation in an adult because it is accessible and easy to locate on the wrist's radial aspect, just beneath the thumb. This pulse site effectively indicates the heart's current output and blood flow to the extremities. It provides quick feedback in routine assessments and is less invasive than other sites, making it particularly useful in prehospital care settings.

While other pulse sites, such as the femoral and carotid, are also important, the radial pulse is preferred for routine checks because of its convenience. The brachial pulse is often used in infants or when assessing blood pressure, but the radial pulse remains the primary choice in adult patients for a quick circulation assessment.
