Effect of Pneumatic Tourniquet on Muscle Oxygen Tension [PDF]
Acta Orthopaedica Scandinavica, 1978 Recent investigations suggest that circulation in a limb can be reduced with a tourniquet to less than 1 per cent of the control limb, or even completely occluded. The development of tissue oxygen tonometry with implanted silastic tubes has provided new possibilities for assessing muscle tissue oxygen tension.
