Patent Images
1. A monitor, comprising:
- an input circuit configured to receive a plethysmographic signal;
a memory storing an algorithm configured to calculate a physiological parameter and one or more characteristics of a trend of the physiological parameter based on the plethysmographic signal; and
a processor configured to execute the algorithm, wherein the processor is configured to execute the algorithm at a first rate per second associated with a high power mode or a second rate per second associated with a low power mode based on the one or more characteristics of the trend of the physiological parameter, wherein the first rate per second is higher than the second rate per second.

Abstract
Embodiments of the present disclosure relate to a system and method for reducing power consumption of a medical device based on one or more physiological parameters. For example, the medical device may be operated in a low power mode if a physiological parameter trend is above a certain threshold. In the low power mode, the processing power may be reduced relative to a high power mode. The low power mode may be associated with reduced processing and output rate.
