摘要： A pressure support system and method of using same that includes a pressure generator adapted to provide a gas flow, a conduit coupled to the pressure generator to deliver a gas flow to a patient, an interface device coupled to the conduit to communicate the gas flow to an airway of the patient. An exhaust vent that provides a flow of exhaust gas to atmosphere is provided in the conduit or the interface device. A flow sensor detects a rate at which gas flows in the conduit and provides a first output indicative thereof, and a pressure sensor detects a pressure of gas at the patient and provides a second output indicative thereof. A control system receives the first and second outputs and determines whether a current flow of exhaust gas passing through the exhaust vent is below an alarm threshold based on the first and second outputs and provides a third output indicative of this determination.

摘要： A high frequency pressure oscillation device that selective restricts the flow of breathing gas to or from a patient to produce pressure spikes in the patient's airway that facilitate clearing secretions from the patient's airway. The device includes a patient circuit that defines a closed path between a source of breathing gas and the patient's airway. A valve is disposed in the patient circuit such that in an open position the path between the source of breathing gas and the airway of the patient is substantially unobstructed. When the valve is in a closed position, the path between the source of breathing gas and the patient's airway is at least partially obstructed to create the pressure spikes. An actuating system associated with the valve alternatively places the valve in the open position and in the closed position at a predetermined oscillation rate that is independent of patient effort.
摘要翻译：一种高频压力振荡装置，其选择性地限制呼吸气体到达或来自患者的气体，以产生患者气道中的压力尖峰，从而有助于从患者气道清除分泌物。该装置包括限定呼吸气体源与患者气道之间的封闭路径的患者回路。阀门设置在患者回路中，使得在打开位置，呼吸气体源和患者的气道之间的路径基本上不受阻碍。当阀处于关闭位置时，呼吸气体源与患者气道之间的路径至少部分阻塞以产生压力峰值。与阀相关联的致动系统可替代地将阀置于打开位置并且处于关闭位置以与患者努力无关的预定振荡速率。
