Abstract

The spectrophotometric technique used in pulse oximetry makes it possible to measure the oxygen saturation of arterial blood noninvasively and continuously. The accuracy of pulse oximeters tends to decrease during extreme hypoxemia, and so the lowest values of the oxygen saturation can not be evaluated with known error, as yet. Furthermore, it is mostly in this range that many undesirable influences interfere with the measurement reliability. Thus, it can be helpful to observe and analyze what factors and to what extent they affect the applied processing procedures. The author of this paper describes the main results of her studies with the focus on the performances of the device specially made for her research.
