SELECTION OF ENSEMBLE AVERAGING WEIGHTS FOR A PULSE OXIMETERBASED ON SIGNAL QUALITY METRICS

摘要

A method and a system for ensemble averaging signals in a pulse oximeter,
including receiving first and second electromagnetic radiation signals from a
blood perfused tissue portion corresponding to two different wavelengths of
light, obtaining an assessment of the signal quality of the electromagnetic
signals, selecting weights for an ensemble averager using the assessment of
signal quality, and ensemble averaging the electromagnetic signals using the
ensemble averager.
