    摘要: A sleep stage classification system (330) is provided. A sleep stage analyzing is performed based on an output signal (100a) of a PPG sensor (100). An estimation unit (310) is adapted to estimate features associated to a respiratory effort of a user based on the output signal (100a) of the PPG sensor (100) and to output a respiratory effort feature signal. A respiratory effort determining unit (320) is adapted to determine to respiratory effort based on the respiratory effort feature signal from the estimation unit (310). A sleep stage classification unit (330) is adapted to classify a sleep stage of a user based on the determined respiratory effort from the respiratory effort determining unit (320) and to output a sleep stage classification signal (310).

    摘要: A system (400) for monitoring an individual's sleep includes: (i) a patient monitor (410) configured to obtain a patient waveform, the patient waveform comprising information representative of a vital statistic of the patient; a processor (420) in communication with the patient monitor and configured to: (i) process the patient waveform to generate a segmented waveform; (ii) extract at least one feature from a segment of the waveform in a time domain and/or at least one feature from the segment of the waveform in the frequency domain; (iii) classify, using the at least one extracted feature, a sleep stage of the patient for the segment of the waveform; and (iv) generate, from classified sleep stages for a plurality of segments of the waveform, a sleep quality measurement; and a user interface (480) configured to report the generated sleep quality measurement.

    摘要: A system for delivering sensory stimulation comprises a sensor configured to measure autonomic nervous system activity information of a user during a sleep session; a sensory stimulator configured to deliver sensory simulation to the user during the sleep session; and a computer system. One or more physical processors of the computer system are programmed with computer program instructions which, when executed cause the computer system to: obtain the autonomic nervous system activity information of the user; determine parasympathetic nervous system information based on the obtained autonomic nervous system activity information of the user; and provide input to the sensory stimulator based on the determined parasympathetic nervous system information, the provided input causing the sensory stimulator to deliver the sensory stimulation to the user based on the determined parasympathetic nervous system information.

    摘要: The present disclosure describes a sleep staging system. The system comprises: one or more sensors configured to generate output signals conveying information related to breathing parameters of subject during a respiratory therapy session; and one or more physical computer processors configured by computer readable instructions to: determine, based on the output signals, one or more breathing features of individual breaths of the subject; determine a distribution of the one or more breathing features over a plurality of time windows, at least one of the time windows having a length of at least 60 seconds; determine sleep states of the subject by mapping the distribution of the breathing features to one or more sleep states using a sleep stage classifier model, the sleep stage classifier model configured to determine the sleep states; and provide feedback indicating the sleep states during the respiratory sleep session.
