Abstract

The author presents the problems related to pulse oximetry, taking into account both the current state-of-the-art as well as her own long-standing experience in this field. The COVID-19 pandemic continues and has raised interest in home application of pulse oximeters due to their potential benefit, which may be warning of a drop in blood oxygenation due to lower respiratory capacity. However, it should be emphasized that these devices have limitations, both of a physiological and technical nature, and some problems related to the reliability and scope of the measurements still remain unresolved. Phenomena which limit processing reliability of the quantity to be sensed, i.e., the oxygen saturation SaO2%, are presented. Specific groups of affecting factors are distinguished in an approach of their contribution to the measurement uncertainty components.
