An automatic pneumatic tourniquet apparatus for occluding blood flow in a person's limb includes an adjustable pneumatic tourniquet (16) operable to vary the pressure applied about the limb, a systolic blood pressure monitor (14) and a control circuit responsive to changes in the blood pressure measured by the pressure monitor to operate the tourniquet to maintain the pressure about the limb at a level greater than the person's blood pressure by a predetermined amount. The apparatus maintains tourniquet pressure at a minimum acceptable level and thereby minimizes nerve damage caused by the compression of the tourniquet on nerve tissues over long periods. |
