System and method for determining spectral boundaries for sleep stage classification

A method to determine spectral boundaries for sleep stage classification in a subject with a determination system, the determination system comprising one or more sensors and one or more physical computer processors, the method comprising:

• generating, with the one or more sensors, output signals that convey information related to a respiratory wave amplitude metric for a sleep session of the subject;
• transforming, with the one or more physical computer processors, the information conveyed by the output signals in individual epochs of time into a frequency domain;
• determining, with the one or more physical computer processors, individual frequencies of respiratory wave amplitude metric peaks within the individual epochs of time;
• determining, with the one or more physical computer processors, an aggregated frequency of the respiratory wave amplitude metric peaks by aggregating the individual frequencies of the respiratory wave metric peaks within the individual epochs of time;
• determining, with the one or more physical computer processors, the spectral boundaries for sleep stage classification for the subject based on the aggregated frequency;
• and
• determining, with the one or more physical computer processors, sleep stages of the subject during individual epochs of time in a subsequent sleep session as a function of the aggregated frequency of respiratory wave amplitude metric peaks using the determined spectral boundaries.
