How much blood flows through the carotid artery?

In normal healthy subjects, the flow varies within ± 6.7% (2SD) at one sitting (intrasession) and ± 21.2% (2SD) from week to week (intersession study). Carotid blood flow varies linearly with PaC02 and increased markedly in response to endotracheal intubation.

What does the carotid artery do?

The carotid arteries are a pair of blood vessels located on both sides of your neck that deliver blood to your brain and head.

Can you feel if your carotid artery blocked?
