Collecting sleep quality information via a medical device
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, with a processor of the medical device or a processor of a computing device configured to communicate with the medical device, a plurality of scalable values of a metric that is indicative of sleep quality over time, each of the scalable values of the sleep quality metric determined based on values of the at least one physiological parameter that were determined during delivery of the therapy according to at least one of a plurality of therapy parameter sets;
for each of the plurality of scalable sleep quality metric values, identifying, with the processor of the medical device or the processor of the computing device, at least one of the plurality of therapy parameter sets used to deliver the therapy by the medical device when the sleep quality metric value was determined;
associating, with the processor of the medical device or the processor of the computing device, each of the determined values of the scalable sleep quality metric values with the at least one of the plurality of therapy parameter sets;
for each of the plurality of therapy parameter sets, determining, with the processor of the medical device or the processor of the computing device, a representative value of the sleep quality metric based on the scalable values of the sleep quality metric associated with the therapy parameter set; and
for each of the plurality of therapy parameter sets, storing, with the processor of the medical device or the processor of the computing device, the representative value of the sleep quality metric in a non-transitory memory.

Abstract
At least one of a medical device, such as an implantable medical device, and a programming device determines values for one or more metrics that indicate the quality of a patient'"'"'s sleep. Sleep efficiency, sleep latency, and time spent in deeper sleep states are example sleep quality metrics for which values may be determined. In some embodiments, determined sleep quality metric values are associated with a current therapy parameter set. In some embodiments, a programming device presents sleep quality information to a user based on determined sleep quality metric values. A clinician, for example, may use the sleep quality information presented by the programming device to evaluate the effectiveness of therapy delivered to the patient by the medical device, to adjust the therapy delivered by the medical device, or to prescribe a therapy not delivered by the medical device in order to improve the quality of the patient'"'"'s sleep.
