Abstract
An improved pulse oximeter apparatus and method for the measurement of oxygen saturation in the blood, which is faster and more accurate than conventional pulse oximeters. Improved speed and accuracy is attained by elimination of normalization and feedback circuitry and the use of analog to digital converting devices having a wide dynamic range along with a sophisticated computer analysis. The instant invention eliminates inaccuricies resulting from channel matching errors, and detects and eliminates aberrant input data.
