SYSTEM AND METHOD FOR SLEEP SESSION MANAGEMENT BASED ON SLOW WAVE SLEEP ACTIVITY IN A SUBJECT

摘要

The present disclosure pertains to a system and method for managing a sleep session of a subject. Managing the sleep session is based on slow wave activity in the subject during the sleep session. Slow wave activity is related to sleep pressure. Sleep pressure dissipates and/or decreases as the subject sleeps. The dissipation dynamics depend on a given subject. The manner in which dissipation occurs regulates the length of the given sleep session and is linked to the temporal dynamics of slow wave activity. The system is configured to determine a metric indicating sleep pressure dissipation and, responsive to the determined sleep pressure dissipation metric indicating that sleep pressure dissipation has reached a dissipation threshold level during the sleep session, wake the subject.

主权项

1. A system configured to manage a current sleep session of a subject, the system comprising:
one or more sensory stimulators configured to provide sensory stimuli to the subject; one or more sensors configured to generate output signals conveying information related to a current sleep stage of the subject during the current sleep session; and one or more processors configured to execute computer program modules, the computer program modules comprising: a sleep parameter module configured to determine one or more sleep parameters based on the output signals, the one or more parameters including a sleep pressure, the sleep pressure being related to slow wave activity in the subject during the current sleep session, the sleep pressure indicating a remaining need for sleep in the subject; a sleep pressure dissipation module configured to determine a metric indicating sleep pressure dissipation in the subject during the current sleep session, the metric determined based on the sleep pressure determination; and a control module configured to, responsive to the determined sleep pressure dissipation metric indicating that sleep pressure dissipation has reached a dissipation threshold level indicating that the subject does not need additional sleep during the current sleep session, control the one or more sensory stimulators to generate a waking stimulus, wherein the waking stimulus comprises sensory stimulation that wakes the subject from sleep.
