An anti-necrosis tourniquet device utilizes an air compressor, programmable through a microprocessor, to enable a user to set periodic cycles of increased and decreased pressure in a pressure cuff as a temporary measure to address a severely hemorrhaging wound on an extremity. When a situation arises to employ a tourniquet, the cuff is applied to a proximal region of the wound. The device is activated to increase pressure in the cuff to occlude the flow of blood to the wound for a programmed period of time after which the program decreases pressure in the cuff to supply blood to the wounded extremity for another selected time period to obviate necrosis of the tissue. This modulated cycle is repeated until a patient receives full medical treatment.
