Controlling therapy based on sleep quality
First Claim
1. A method comprising:
- monitoring at least one physiological parameter of a patient via a medical device that delivers a therapy to the patient;
determining a value of a metric that is indicative of sleep quality based on the at least one physiological parameter; and
controlling delivery of the therapy by the medical device based on the sleep quality metric value, wherein monitoring at least one physiological parameter comprises monitoring at least one of electrocardiogram morphology, subcutaneous temperature, muscular tone, electrical activity of a brain of the patient or eye motion.

Abstract
A medical device, such as an implantable medical device (IMD), determines values for one or more metrics that indicate the quality of a patient'"'"'s sleep, and controls delivery of a therapy based on the sleep quality metric values. For example, the medical device may compare a sleep quality metric value with one or more threshold values, and adjust the therapy based on the comparison. In some embodiments, the medical device adjusts the intensity of therapy based on the comparison, e.g., increases the therapy intensity when the comparison indicates that the patient'"'"'s sleep quality is poor. In some embodiments, the medical device automatically selects one of a plurality of therapy parameter set available for use in delivering therapy based on a comparison sleep quality metric values associated with respective therapy parameter sets within the plurality of available therapy parameter sets.

11. A medical device comprising:
-
a therapy module to deliver a therapy to a patient; and
a processor to monitor at least one physiological parameter of a patient based on at least one signal received from at least one sensor, determine a value of a metric that is indicative of sleep quality based on the at least one physiological parameter, and control delivery of the therapy by the therapy module based on the sleep quality metric value, wherein the processor monitors at least one of electrocardiogram morphology, subcutaneous temperature, muscular tone, electrical activity of a brain of the patient or eye motion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
