    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).

    Abstract: A low-cost CPAP apparatus in which, upon detection of the transition from inhalation to exhalation, the blower motor is de-energized to allow it to freewheel. When the pressure in the patient mask (or whatever interface is utilized) reaches a minimum pressure level during exhalation, the motor is re-energized and its speed is controlled so to maintain the pressure at a level suitable for exhalation. Upon detection of the transition from exhalation to inhalation, the motor speed is increased to provide higher pressures in the patient mask suitable for inhalation.

    Abstract: Methods and/or apparatuses for treating sleep-disordered breathing (SDB) are provided. In particular, systems and/or methods are provided which may temporarily boost the pressure of a supply of breathable gas provided by an AutoSet device for the treatment of hypopnea. In certain example embodiments, a supply of breathable is provided to patients to treat apneas and/or hypopneas. The presence and/or absence of apneas and/or hypopneas are detected (e.g. by monitoring the Apnea-Hypopnea Index). When hypopnea events are detected, the pressure of the supply of breathable gas temporarily is increased above the Pcrit and/or CPAP levels, at least during patient inspiration. When the hypopnea events are normalized, the pressure is reduced. In certain example embodiments, the pressure will not be increased when a non-hypopnea event is detected at the same time as a hypopnea event.
