The relationship between tourniquet pressure and underlying soft-tissue pressure in the thigh.

Abstract

the use of a pneumatic tourniquet is potentially associated with injury to underlying muscles, vessels, and nerves if excessive pressure occurs beneath the tourniquet. In order to minimize the risk of soft-tissue injury, the lowest tourniquet pressure that maintains a bloodless field should be used. A nomogram based on data generated in this experiment is provided as a guide to determining appropriate tourniquet pressures.
