Abstract
A physiological monitoring system may receive a sensor signal from a physiological sensor. The system may determine a parameter based on the sensor signal, for example variability of a blood oxygen saturation value or the percent modulation of a light signal. The system may determine a light drive parameter limit based on one or more parameters. For example, the system may determine a light drive current limit. The frequency of changes in the limit may be regulated using a state machine and other techniques that include hysteresis. An extant light drive parameter may be updated or changed in accordance with the light drive parameter limit and a light drive signal may be generated based on the light drive parameter.
