The commonly used site to feel a pulse is radial artery on the wrist, the point where radial artery approaches the wrist present at the middle of wrist.
When we placed our fingers in the middle of wrist, we can feel the pulse wave. That is 72 beats per minutes. The radial artery is the site of insertion of the arterial line, for monitoring the blood pressure. It is selected because it is accessible due to the low incidence of the complications such as thrombosis.
The pressure of the blood is always high in the arteries comparative to the veins, usually arteries are present deep in the body, the radial artery in only artery that approaches the skin. Hence, it is used to monitoring the pulses.
