to see if the pulse rate is beating at a normal rate
The pulse can be located in various places on the body, including the wrist (radial pulse), neck (carotid pulse), inner elbow (brachial pulse), groin (femoral pulse), behind the knee (popliteal pulse), on top of the foot (dorsalis pedis pulse), and behind the ear (posterior auricular pulse).
Field vision refers to the full extent of what a person can see without moving their eyes. It includes both central vision (what you see directly in front of you) and peripheral vision (what you can see out of the corners of your eyes). It is not the same as your outermost vision, which could refer to what is at the edges of your peripheral vision.
It is usually easiest to find the brachial pulse under the bicep, in the arm. The carotid pulse can be a little tricky, but if you can see it, you can get the rate visually.
Vision is always real, expect when blind, but your vision can deceive you. It can trick you. You can see something that's not really there. Or you can't see something that really is there.
