Collecting sleep quality information via a medical device
First Claim
1. A method comprising:
- delivering, by a medical device system, electrical stimulation therapy to a patient according to a plurality of different therapy parameter sets;
monitoring, by the medical device system, at least one physiological parameter of the patient;
determining when the patient is asleep, and detecting occurrences of at least one of arousals and apneas when the patient is asleep based on the at least one physiological parameter;
associating each detected occurrence of an arousal or an apnea with a corresponding one of the plurality of different therapy parameter sets according to which the medical device delivered the therapy when the occurrence of the arousal or the apnea was detected;
for each of the plurality of different therapy parameter sets;
determining a plurality of values of a sleep quality metric based on the occurrences of the at least one of arousals and apneas associated with the corresponding therapy parameter set, each value of the plurality of values of the sleep quality metric indicating a number of the arousals or apneas over a period of time; and
determining a representative value of the sleep quality metric for the therapy parameter set based on the plurality of values of the sleep quality metric associated with the therapy parameter set;
storing the representative values of the sleep quality metric and an indication of the association of the therapy parameter sets with the respective representative values of the sleep quality metric; and
automatically adjusting the delivery of the electrical stimulation therapy to the patient based on the determined 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. 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.
