Patent Images
1. A method for reducing processing load of a patient monitor in communication with a physiological sensor, the physiological sensor configured to emit light towards a tissue site, detect the light after it has been attenuated by tissue, and output a signal responsive to the detected light, the method comprising:
- receiving, at the patient monitor, the signal from the physiological sensor, wherein the signal corresponds to physiological data and comprises a plurality of features including at least a first feature and a second feature;
associating a category of a first set of categories with the first feature;
associating a category of a second set of categories with the second feature;
determining an action from a set of actions to perform based at least in part on a combination of at least a first value corresponding to the category associated with the first feature and a second value corresponding to the category associated with the second feature; and
causing the determined action to be performed.

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.

12. A patient monitoring system comprising:
-
one or more processors in communication with a physiological sensor that is configured to emit light towards a tissue site, detect the light after it has been attenuated by tissue, and output a signal responsive to the detected light, the one or more processors configured to; receive the signal from the physiological sensor, wherein the signal corresponds to physiological data and comprises a plurality of features including at least a first feature and a second feature, associate a category of a first set of categories with the first feature and a category of a second set of categories with the second feature, determine an action from a set of actions to perform based at least in part on a combination of at least a first value corresponding to the category associated with the first feature and a second value corresponding to the category associated with the second feature, and cause the determined action to be performed. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. 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, at a patient monitor, a signal from a physiological sensor, wherein the signal corresponds to physiological data and comprises a plurality of features including at least a first feature and a second feature; associating a category of a first set of categories with the first feature and a category of a second set of categories with the second feature; determining an action from a set of actions to perform based at least in part on a aggregation of at least a first value corresponding to the category associated with the first feature and a second value corresponding to the category associated with the second feature; and causing the determined action to be performed.
