Can anyone else feel where their veins are for drawing blood when the tourniquet is on and the the person is feeling around for a vein? It feels like pressure in a vein. I can guide them to it every time because my veins are quite deep. Also, I learned today that with the manual blood pressure machine, I can tell my blood pressure by watching the levels and feeling when the pulsating in my arm starts, stops and starts again. I can weird doctors and nurses out with 2 things now. Knowing where my vein is and what my blood pressure is before they tell me.
