Abstract:
The present invention relates to a determination system, a corresponding determination method and a computer program for determining a sleep stage of a subject. The determination system comprises a cardiorespiratory signal providing unit ( 10 ), an actigraphy data providing unit ( 20 ), a first sleep stage determination unit ( 30 ) for determining the sleep stage based on a cardiorespiratory signal, and a second sleep stage determination unit ( 40 ) for determining the sleep stage based on actigraphy data. The first sleep stage determination unit ( 30 ) determines a sleep onset latency (SOL) of the subject. The sleep stage of the subject is determined using the first sleep stage determination unit ( 30 ) up to the SOL and the second sleep stage determination unit ( 40 ) after the SOL. The determination system and corresponding method allow for a more reliable determination of a sleep stage of subject, in particular improve the determination of the SOL of the subject.

Claim (Index 1):
A determination system for determining a sleep stage of a subject, wherein the determination system comprises:\n a cardiorespiratory signal providing unit for providing a cardiorespiratory signal of the subject, an actigraphy data providing unit for providing actigraphy data of the subject, a first sleep stage determination unit for determining the sleep stage of the subject based on the cardiorespiratory signal of the subject, a second sleep stage determination unit for determining the sleep stage of the subject based on the actigraphy data of the subject, and a determination control unit for determining one out of the first sleep stage determination unit and the second sleep stage determination unit for determining the sleep stage of the subject, wherein the first sleep stage determination unit is configured to determine a sleep onset latency of the subject, and wherein the determination control unit is configured to determine the sleep stage of the subject using the first sleep stage determination unit up to the sleep onset latency and to determine the sleep stage of the subject using the second sleep stage determination unit after the sleep onset latency.
