Oxygen and Carbon Dioxide Tensions in the Gastrocnemius Muscles of Patients with Lower Limb Arterial Ischaemia
Currently, commonly used parameters in assessing circulatory status of ischaemic limbs include peripheral pulse status, temperature and color of the extremities, type of ischaemic pain, claudication distance, capillary and venous filling, condition of the skin and nails, and arteriography. If necessary equipment and personnel are available, peripheral blood pressure measurements, pletysmography, thermography and radioactive clearance techniques may also be used to evaluate limb circulation. However, most of these parameters provide, at best, only indirect information of tissue nutrition in the ischaemic area. Recently, several investigations have demonstrated that measurements of skeletal muscle oxygen and carbon dioxide tensions provide an excellent index of peripheral tissue perfusion (Furuse et al, 1973; Brantigan et al, 1974; Wakabayashi et al, 1975).
