Collecting sleep quality information via a medical device
First Claim
1. A medical system comprising:
- a medical device that delivers a therapy to a patient, and monitors at least one physiological parameter of the patient based on a signal received from at least one sensor;
a processor tat determines a plurality of values of a metric that is indicative of sleep quality over time, each of the values of the sleep quality metric determined based on values of the at least one physiological parameter determined during delivery of the therapy by the medical device according to at least one of a plurality of therapy parameter sets, and associates each of the determined values of the sleep quality metric with the at least one of the plurality of therapy parameter sets and, for each of the plurality of therapy parameter sets, determines a representative value of the sleep quality metric based on the values of the sleep quality metric associated with the therapy parameter set, wherein the representative value for each therapy parameter set comprises one of a mean value or a median value; and
a memory that receives the sleep quality metric values, the representative values, and an indication of the therapy parameter sets associated with the sleep quality metric values and representative values.

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 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.
