1. A method for reducing processing load of a patient monitor, the method comprising:
- emitting light from a light emitter of a physiological sensor;
detecting the light at a detector of the physiological sensor after the light has been attenuated by tissue;
receiving at a patient monitor physiological data from the physiological sensor based at least in part on the light detected at the physiological sensor, wherein the physiological data is characterized by a plurality of features including at least a first feature and a second feature;
associating a category of a first plurality of categories with the physiological data, the first feature characterized by the first plurality of categories;
associating a category of a second plurality of categories with the physiological data, the second feature characterized by the second plurality of categories;
assigning a first value to the physiological data based at least in part on the category of the first plurality of categories;
assigning a second value to the physiological data based at least in part on the category of the second plurality of categories;
determining an action from a set of actions to perform based at least in part on an aggregation of at least the first value and the second value; and
performing the determined action.

Abstract
A patient monitor including a physiological measurement logic engine receives physiological data from a physiological sensor. The logic engine abstracts one or more features of the physiological data and determines a category for the abstracted feature. The logic engine further encodes the category of each of the one or more features and determines an action to perform based on the encoded categories.
