CURRENT ASPECTS OF METROLOGICAL SUPPORT TO OPTICAL PULSE OXIMETRY

摘要

It is shown that the metrological support system used throughout the world for optical pulse oximetry does not provide unification and an acceptable error level in measurements of blood oxygen saturation. A new method is proposed for calculating saturation and saturation errors, which enables one to reduce the measurement error to a level that meets current metrological specifications. Ways are considered of reducing the errors in optical pulse oximetry further.
