METHODS AND SYSTEMS FOR LIGHT SIGNAL CONTROL IN A PHYSIOLOGICAL MONITOR

摘要

A physiological monitoring system may select a light signal for determining a physiological parameter. In some embodiments, the monitoring system may select a received light signal for further processing based on a physiological metric such as blood oxygen saturation value, or based on a system metric such as a signal-to-noise ratio. In some embodiments, the system may determine a light drive parameter based on a received signal. For example, the system may select a received light signal for further processing in order to determine a physiological parameter.

主权项

1. A method of determining a physiological parameter of a subject, the method comprising:
receiving, using processing equipment, two or more light signals attenuated by a subject, wherein each respective light signal corresponds to a different wavelength of light; determining, using processing equipment, a metric based at least in part on at least one of the two or more received light signals; selecting, using processing equipment, at least one of the two or more light signals based on the metric; and determining, using the processing equipment, a physiological parameter of the subject based on the at least one selected light signal.
