It's easy to measure. It's a good way to get a consistent measurement. It's closer to the pump, so it's less likely to be reduced by arterial blockage. It's at nearly the same elevation as the pump, so it's less likely to be affected by gravity and pooling of blood in the lower extremities. It's a pressure point that's easier to block, so you're more likely to get a good measurement that's less dependent on the skill of the technician.

Pressure is greater there. Close to the heart, while artery in leg is being pulled down (less pressure) to bring oxygen to the lower extremities.

If you search on www.google.com. I'm sure that you will find some information on it.
