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.

Methods and systems for determining a light drive parameter limit in a physiological monitor

Provided herein are methods and apparatuses for facilitating clinical acceptance of patient monitoring features. These methods may be used in conjunction with a computer that includes software for viewing the type of display associated with the monitoring feature. The clinical acceptance systems as provided herein may display a new or experimental monitoring feature along with a benchmark feature that a clinician is familiar with. In certain embodiments, the viewing tool may be isolated from the calculation tools so that the computer may include stored files that are in a format ready for display.
