The present invention relates to an oximeter for monitoring oxygen saturation of arterial blood. Light of two wavelengths is transmitted through a specimen. Detectors measure the attenuation of light through the specimen to produce two modulating data streams. The data streams are thereafter processed, evaluated, and compared to determine oxygen saturation. A novel method to process, evaluate and compare the two data streams is disclosed.
