With respect tо the first step in hemоstаsis - vаsоconstriction, when а vessel is cut paracrine molecules which are vasoconstrictive are released to slow blood flow/blood loss and this is similar to what you are trying to achieve more drastically by applying a tourniquet to a hemorrhage site. Say someone goes to draw blood from a patient's superficial lower pressure MC (median cubital) vein but punctures the deeper higher pressure brachial artery accidently (they never learned their surface anatomy...). Does vasoconstriction and thus the indicated site for a tourniquet need to occur superior/proximal or inferior/distal to the vessel break? Hint: think about flow from the left side of the heart out to the systemic circulation.
