Method and apparatus for assessing sleep quality
First Claim
1. A method of assessing sleep quality of a patient undergoing therapy for a sleep disorder, the method comprising:
- by way of a sensor, obtaining sleep session data comprising physiological parameters of the patient during a sleep session in which the patient undergoes the therapy, the parameters including at least sleep duration and sleep fragmentation; and
by way of a processor;
processing the sleep session data and subjective patient data to determine a composite sleep quality index indicative of the patient'"'"'s sleep session quality;
determining directions for adjustment of a therapy apparatus for future therapy sessions based on the composite sleep quality index;
displaying the directions on a display device; and
adjusting parameters of the therapy apparatus based on the determined directions.

Abstract
Systems and/or methods for assessing the sleep quality of a patient in a sleep session are provided. Data is collected from the patient and/or physician including, for example, sleep session data in the form of one or more physiological parameters of the patient indicative of the patient'"'"'s sleep quality during the sleep session, a subjective evaluation of sleep quality, etc.; patient profile data; etc. A sleep quality index algorithm, which optionally may be an adaptive algorithm, is applied, taking into account some or all of the collected data. Sleep quality data may be presented to at least the patient, and it may be displayed in any suitable format (e.g., a format useful for the patient to be appraised on the progress of the treatment, a format useful for a sleep clinician to monitor progress and/or assess the effectiveness of differing treatment regimens, etc).

9. An apparatus for assessing sleep quality of a patient undergoing therapy for a sleep disorder, comprising:
-
at least one sensor configured to obtain sleep session data during a sleep session in which the patient undergoes said therapy, said sleep session data comprising physiological parameters of the patient indicative of the patient'"'"'s sleep quality during the sleep session, the patient'"'"'s sleep quality including at least sleep duration and sleep fragmentation; and a processor configured to (a) determine a composite sleep quality index indicative of the patient'"'"'s sleep session quality using the sleep session data and subjective patient data, (b) determine directions for adjustment of a PAP device based on the composite sleep quality index, and (c) communicate feedback to the patient regarding the directions and/or adjust the PAP device based on the directions. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
