A tourniquet is used to elevate the blood pressure in the veins of the arm. This helps to ease and speed up the process. Sometimes the donor is given an object to squeeze repeatedly in order to increase blood flow to the targeted vein. Invariably a needle with a larger gauge is used in order to minimize the shearing forces that can cause damage to the RBC’s.
A mild sting may be experienced when the needle is inserted, but there should be no pain during the donation.
