| 20130247906 | LIFE STYLE FLOW GENERATOR - A method for delivering a therapeutic or medicinal substance, comprising sensing a patient to generate a sleep stage signal indicating a patient's sleep stage, and releasing and/or delivering a therapeutic or medicinal substance via the patient's airways in accordance with the sleep stage signal. | 09-26-2013 |
| 20130247911 | POSITIVE AIRWAY PRESSURE DEVICE - A positive airway pressure (PAP) device for supplying a flow of breathable gas to a patient includes a first housing; a flow generator provided in the first housing, the flow generator configured to generate a flow of breathable gas; a second housing configured to be connected to the first housing, the second housing including a channel having an inlet configured to receive the flow of breathable gas and an outlet configured to discharge the flow of breathable gas, wherein the first housing is provided on top of the second housing such that a footprint of the PAP device is not substantially increased beyond a footprint of the second housing. | 09-26-2013 |
| 20130319415 | ACCLIMATIZATION THERAPY FOR FIRST TIME USERS - Systems, methods, and/or apparatuses for acclimatizing a user to positive airway pressure (PAP) therapy are provided. Generally, a sub-therapeutic treatment pressure is provided initially. It may be ramped up to a full treatment pressure over the course of one or more therapy sessions. The pressure level may be ramped up based on, for example, sleep state, sleep phase, patient compliance with types of treatment (e.g. bilevel vs. CPAP, etc.), clinician input (either at the site, remotely, via pre-programmed smartcards, etc.), etc. Such techniques may be used alone or in combination. | 12-05-2013 |
| 20130340762 | MASK AND MASK CUSHION THEREFOR - A cushion comprises a substantially triangularly shaped frame from which extends a membrane. The membrane is spaced away from the rim of the frame, and its outer surface is of substantially the same shape as the rim. The seal forming portion thus contacts both the surface of the wearer's nose and a portion of the wearer's face. The shape of the seal forming portion is particularly suited to effectively seal the difficult region of the facial contour that is the crease between the sides of the nose and the face. | 12-26-2013 |
| 20140076318 | METHOD AND APPARATUS FOR ASSESSING SLEEP QUALITY - 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). | 03-20-2014 |
