Patent ID: 11103661

Abstract:
Methods and/or apparatus automate setting of a pressure ramp to permit pressure to gradually arrive at a treatment pressure such as in the initial or pre-sleep stages of use of a respiratory therapy pressure device for treatment of a respiratory disorder during sleep (e.g., sleep disordered breathing). In an example, apparatus for treating a respiratory disorder may include a breathable gas pressure generating device. The apparatus may include a controller, including a processor(s). The controller may be configured to collect historic sleep onset parameter(s) concerning timing of a patient falling asleep. The apparatus may determine, based on the historic sleep onset parameter(s), a pre-sleep limit. The apparatus may determine a pre-sleep profile of pressure versus time having a duration spanning the pre-sleep limit and having a plurality of ramping sub-therapeutic pressures. The apparatus may control, upon initiation of treatment, setting of the pressure generating device according to the pre-sleep profile.
