PULSE OXIMETER WITH SEPARATE ENSEMBLE AVERAGING FOR OXYGEN SATURATION AND HEART RATE

摘要

The use of two separate ensemble averagers for processing a detected waveformfor use in calculating oxygen saturation and a pulse rate. The ensembleaverager used for calculating oxygen saturation operates on a signal which hasbeen normalized, while the ensemble averager for the pulse rate calculationoperates on a signal which has not been normalized. The metrics chosen for thetwo paths through the two ensemble averagers can be varied to optimize theensemble averaging for oxygen saturation or pulse rate calculations.
