Sleep state classification
First Claim
Patent Images
1. A method of providing therapy to a patient, comprising:
- identifying a sleep-wake status of the patient;
sensing pectoral muscle tone using a sensor of an implantable stimulation device implanted in a pectoral region;
detecting REM sleep status based on the pectoral muscle tone;
classifying one or more sleep states based on the sleep-wake status and the REM sleep status, wherein the classifying, the detecting the sleep-wake status, and the detecting REM sleep status are performed at least in part implantably; and
providing at least one of sleep state informed monitoring, diagnostics and therapy to the patient using the sleep state classification.

Abstract
Systems and methods for sleep state classification involve detecting conditions related to sleep, including at least one condition associated with rapid eye movement (REM) sleep. Additionally, a condition modulated by the sleep-wake status of the patient may be detected. A medical system that is partially or fully implantable incorporates sensors and circuitry for detecting and processing the sleep-related signals. A sleep state processor classifies the patient'"'"'s sleep state based on the sleep-related signals. Sleep state classification may be used in connection with the delivery of sleep state appropriate therapy, diagnostic testing, or patient monitoring.
