    • A CPAP apparatus including: a variable pressured air source and means to vary the air pressure delivered therefrom; a nose piece for sealed air communication with a patient's respiratory system; an air communication line from the air source to the nose piece; a sound transducer adapted to be in sound communication with the patient's respiratory system; and a feedback system controlling the output pressure of the air source in response to an output from the transducer so as to increase the output air pressure from said air source, in response to detection of sound indicative of snoring, in accordance with a predefined procedure. The sound transducer, in its most general form, comprises a pressure transducer which, in addition to detecting snoring sounds, can detect other respiratory parameters such as the rate of breathing, inhaled air flow volume, and inhaled air flow rate. Output air pressure from air source is increased in response to one or more of these parameters in accordance with a pre-defined procedure.
    • 一种CPAP设备,包括:可变压力空气源和改变从其传送的空气压力的装置; 用于与患者的呼吸系统进行密封空气通信的鼻片; 从空气源到鼻片的空气通信线; 适于与患者呼吸系统进行声音通信的声音换能器; 以及反馈系统,其响应于来自换能器的输出来控制空气源的输出压力,以响应于根据预定义的过程检测到指示打鼾的声音来增加来自所述空气源的输出空气压力。 声音传感器在其最通用的形式中包括一个压力传感器,除了检测打鼾的声音之外,还可以检测其他呼吸参数,例如呼吸速率,吸入空气流量和吸入空气流速。 响应于根据预定义过程的这些参数中的一个或多个,来自空气源的输出空气压力增加。
