    Abstract: A flow regulation vent includes a fixed portion adapted to engage a gas supply conduit and a spring force biased movable portion connected by a hinge to the fixed portion and flowingly connected to the pressurized gas supply. The fixed portion includes a gas flow orifice. The movable portion is pivotably movable between 1) a relaxed position, wherein at a specified minimum operating pressure, the movable portion is pivoted by the spring force away from the fixed portion to a position to establish a first gas washout flow area between the movable portion and the gas flow orifice; and 2) a fully pressurized position, wherein at a specified maximum operating pressure, the pressurized gas offsets the spring force to pivot the movable portion to a position adjacent the fixed portion to establish a minimum gas washout flow area between the movable portion and the gas flow orifice.

    Abstract translation: 流量调节通风口包括适于接合气体供应管道的固定部分和通过铰链连接到固定部分并且流体连接到加压气体供应的弹簧力偏置可动部分。 固定部分包括气流孔。 可移动部分可在1）松弛位置之间枢转运动，其中在特定的最小操作压力下，可动部分通过弹簧力从固定部分枢转到建立第一气体冲洗流动区域的位置， 和气流孔口; 和2）完全加压位置，其中在特定的最大工作压力下，加压气体抵消弹簧力以将可移动部分枢转到邻近固定部分的位置，以在可移动部分和气体之间建立最小气体冲洗流动面积 流量孔。

    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: An elbow assembly includes an elbow with an opening in a sidewall of the elbow. An anti-asphyxia valve (AAV) assembly is provided to the elbow. The opening in the sidewall of the elbow is configured to receive at least a portion of the AAV assembly. The elbow assembly further includes a support member with an atmospheric port. The support member is configured to be secured to a portion of the elbow and cover the opening. The AAV assembly is adapted to be secured to the elbow by the support member. In addition, the support member is configured so that an outer surface of the support member is substantially flush with an outer surface of the elbow when the support member is secured to the portion of the elbow.
