Abstract
A one-dimensional optical reflectance model based on the equations of P. Kubelka and F. Munk (1931) has been developed to characterize a reflectance pulse oximeter. Arterial blood volume was varied in order to simulate pulsitile changes in reflectance. It was found that the reflectance ratio versus SaO2 (arterial oxygen saturation) varied significantly with SvO2 (venous oxygen saturation). This effect was simulated by changes in the cardiac output. In addition, effects of changing hematocrit and venous blood volume were examined. Neither of these parameters had a significant effect on the reflectance ratio versus SaO2 plot for the oxygen saturation range most often seen clinically (SaO2 > 80%).
