First Claim
Patent Images
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 detected light at the physiological sensor, wherein the physiological data comprises one or more features;
for each feature of the one or more features, assigning the physiological data to a category of a plurality of categories;
for each feature of the one or more features, assigning a value to the physiological data based at least in part on the assigned category for the respective feature;
determining, using an electronic lookup table, an action from a set of actions to perform based at least in part on the assigned value for each feature, wherein determining the action is based on an aggregation of assigned values when there are multiple features; 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.

11. A patient monitor system comprising:
-
a physiological sensor configured to emit light towards a tissue site, detect the light after it has been attenuated by tissue, and obtain physiological data based at least in part on the detected light; and a patient monitor in communication with the physiological sensor and configured to; receive the physiological data from the physiological sensor; determine one or more features of the physiological data; assign a category of a plurality of categories to the physiological data for each feature of the one or more features of the physiological data; assign a value to the physiological data for each feature based at least in part on the assigned category for the respective feature; associate an action with the physiological data based at least in part on the assigned value for each feature using an electronic lookup table, wherein associating the action with the physiological data is based on an aggregation of the assigned value for each feature when there are multiple features; and perform the action associated with the physiological data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A computer-implemented method for reducing processing load of a patient monitor, the method comprising:
under control of one or more computing devices of the patient monitor; receiving physiological data from a physiological sensor configured to emit light towards a tissue site, detect the light after it has been attenuated by tissue, and obtain the physiological data based at least in part on the detected light; determining one or more features of the physiological data; assigning a category of a plurality of categories to the physiological data for each feature of the one or more features of the physiological data; assigning a value to the physiological data for each feature based at least in part on a corresponding assigned category for the each feature; associating an action with the physiological data based at least in part on the assigned value for each feature, wherein associating the action with the physiological data is based on an aggregation of the assigned value for each feature when there are multiple features; and performing the action associated with the physiological data. - View Dependent Claims (22, 23)
