    Abstract: A method of an apparatus control pressure in the patient interface. A vent valve may be used with a respiratory device, where the vent valve may selectively block fluid communication between components, such as the flow generator, the patient interface, and/or the vent. An expiratory flow model may be used to determine an expiratory characteristic such as an expiratory flow rate or pressure in the patient interface where an indicative measure may not be available. The expiratory flow model may receive inputs based on a measure of the patient's respiration, such as the tidal volume, peak inspiratory flow rate or length of inspiration. The expiratory characteristic may be used by a controller to control a pressure in the patient interface to provide respiratory therapy to a patient at or close to a target pressure.

    Abstract translation: 一种装置控制患者界面压力的方法。 排气阀可以与呼吸装置一起使用,其中排气阀可以选择性地阻止诸如流量发生器,患者接口和/或通气口的部件之间的流体连通。 可以使用呼气流模型来确定呼气特征,例如患者接口中的呼气流量或压力,其中指示性测量可能不可用。 呼气流模型可以基于患者呼吸的测量来接收输入,例如潮气量,吸气峰值吸气流速或吸气长度。 呼气特征可以由控制器用于控制患者界面中的压力,以在或接近目标压力的情况向患者提供呼吸治疗。
