Regional Heterogeneity of PCO2 and PO2 in Skeletal Muscle
Gas pockets in the peritoneal space and subcutaneous tissue have been used for estimation of oxygen and carbon dioxide partial pressures in tissue (Campbell, 1931; Van Liew, 1968). Inside of soft tissue it is difficult to form and later retrieve a gas bubble, so a special technique was devised whereby gas is retained inside a piece of hollow glass capillary tubing (Van Liew, 1962). Gasometric techniques have the major advantage that both PCO2 and PO2 are measured simultaneously.
