Collecting sleep quality information via a medical device
First Claim
1. A method comprising:
- monitoring at least one physiological parameter of a patient;
determining a value of a metric that is indicative of sleep quality based on the at least one physiological parameter;
identifying a current therapy parameter used by a medical device to deliver a therapy to a patient; and
associating the sleep quality metric value with the current therapy parameter set.

Abstract
At least one of a medical device, such as an implantable medical device, a monitor, and a computing 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.

13. A method comprising:
-
monitoring a plurality of signals, each of the signals generated by a sensor as a function of at least one physiological parameter of a patient;
identifying when the patient is attempting to sleep;
identifying when the patient is asleep based on at least one of the signals; and
determining a value of a metric that is indicative of sleep quality based on the identifications of when the patient is attempting to sleep and asleep, wherein identifying when the patient is asleep comprises identifying when the patient is asleep based on at least one of electrocardiogram morphology, subcutaneous temperature, muscular tone, electrical activity within a brain of the patient or eye motion.
