Coupled Transport of O2 and Co2 Within the Upper Skin Simulated by the Capillary Loop Model
The transport of respiratory gases as oxygen and carbon dioxide through tissues and blood and their functional relations has been investigated in the past by numerous authors (for example: Roughton, 1964; Severinghaus, 1966; Thews, 1968; Lübbers, 1979). Due to the introduction of transcutaneous Po2 and Pco2 measuring techniques in clinical medicine (Huch et al., 1981) the transport of oxygen and carbon dioxide through the skin has become of considerable interest. To study those processes in detail we developed a so-called capillary loop model, which simulates the gas and heat transport through the skin including the loop-shaped capillary structure of the upper skin and the nonlinear effects due to the binding of O2 by hemoglobin and temperature shifts (Großmann et al., 1980; Großmann, 1982).
