    • A pressure reducing valve for use in a system adapted to deliver a breathing gas to a patient. The pressure reducing valve is structured to communicate a flow of breathing gas to such a patient's airway during an inspiratory phase. The pressure reducing valve is structured to discharge the flow of breathing gas and a flow of exhaled gas to atmosphere during the expiratory phase. The flow of breathing gas and flow of exhaled gas are discharged to atmosphere through a number of exhaust ports. Because the flow of breathing gas and flow of exhalation gas are discharged through the exhaust ports, less effort is required by a patient during the expiratory phase.
    • 一种用于适于向患者输送呼吸气体的系统中的减压阀。 减压阀被构造成在吸气阶段期间将呼吸气体流传送到患者的气道。 减压阀被构造成在呼气阶段排出呼吸气体流和呼出气体流向大气。 呼吸气体和呼出气体的流动通过多个排气口排放到大气中。 由于呼吸气体的流动和呼出气体的流动通过排气口排出,所以在呼气阶段期间患者需要较少的努力。
