Sleep study using an implanted medical device

A method of performing a sleep study associated with a subject, the method comprising:

• obtaining, using an implantable medical device (IMD), a first physiological parameter signal;
• obtaining a second physiological parameter signal;
• identifying, based on a set of episode data, an occurrence of an episode during a sleep session, the episode corresponding to a sleep disorder, the set of episode data based on at least one of the first physiological parameter signal and the second physiological parameter signal;
• and
• generating, based on the first physiological parameter signal and the second physiological parameter signal, a study report, the study report comprising an indication of the episode.

A method of performing a sleep study associated with a subject, the method comprising:

• obtaining, using a respiratory sensor implanted in the subject, a respiratory signal;
• obtaining, using a posture sensor implanted in the subject, a posture signal;
• obtaining, using a cardiac sensor, a cardiac signal, the cardiac signal comprising a heart rate signal;
• identifying, based on the posture signal and the heart rate signal, an onset of a sleep session;
• identifying, based on the respiratory signal, an occurrence of a respiratory episode during the sleep session;
• annotating the respiratory signal with an annotation corresponding to the respiratory episode;
• correlating, based on the posture signal, a posture with the respiratory episode;
• and
• generating a study report, the study report comprising an indication of the episode and correlation information indicating the correlated posture.
