Slow flow venous doppler

Webb20 jan. 2016 · Flow in the veins is much slower with a much lower pressure. If you were to cut one of your veins then blood would certainly pour out, but since the pressure is low it would be nowhere near as fast or forceful as an arterial bleed. In fact with a venous bleed you could easily stem the flow of blood with gentle pressure over the skin.
