When finding carotid artery, you are looking to check for victim's

pulse

Explanation:

The carotid arteries extend from the aorta to the brain and supply blood to that organ. If you gently press both sides of your trachea in the neck, you may feel carotid artery pulsations. For this reason, we can say that when you find a carotid artery in a person, you try to check for a pulse.

Like any artery in the body, carotids can become diseased if their interior is partially or completely occluded. The material that is deposited inside the arteries is called atheroma and is essentially a fat deposit. It forms a plaque that can eventually cause a narrowing of the carotid artery, which is called stenosis.
