SYSTEM AND METHOD FOR A WAKEFUL SLEEP DETECTION ALARM

摘要

The present disclosure pertains to waking a subject from a period of wakeful sleep by modulation of a flow of breathable gas being delivered to the airway of the subject, with the modulation being performed based on a monitoring of wakefulness of the subject during sleep Typical sleep cycles comprise periods of deeper sleep and/or periods or lighter (wakeful) sleep. Waking during lighter stages of sleep may result in feeling more energetic and well-rested compared to waking from deeper sleep. Sleep therapy such as, for example, continuous positive airway pressure (CPAP), typically monitors sleep characteristics of a subject. These sleep characteristics comprise one or more of tidal volume, pressurized gas leakage (indicating movement), respiration rate, and/or other characteristics. During use of sleep therapy devices, sleep characteristics may be collected during therapy that can be used to determine whether the patient is in light sleep or deep sleep. The present disclosure contemplates utilizing a sleep therapy device in combination with the system described herein to collect sleep characteristics of a subject during sleep, and to wake the subject from wakeful sleep during an alarm window so the subject may feel as well rested and energetic as possible.

主权项

1. A wakeful sleep detection alarm device comprising:
a pressure generator configured to generate a pressurized flow of breathable gas for delivery to the airway of a subject;
one or more sensors configured to generate one or more output signals conveying information related to one or more parameters of the pressurized flow of breathable gas; and one or more processors configured to execute computer program modules, the computer program modules comprising:
a wakefulness module configured to determine wakefulness of the subject based on the one or more output signals;an alarm module configured to determine an alarm window of time; anda control module configured such that, responsive to the determined wakefulness of the subject breaching a threshold during the alarm window of time, the control module controls the pressure generator to generate a waking stimulus, wherein the stimulus comprises modulation of the pressurized flow of breathable gas.
