Abstract: A variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.

Abstract translation: 用于患者连续气道正压通气（CPAP）的变速鼓风机包括气体流路中的两个叶轮，其将气体加压至所需的压力和流动特性。 因此，鼓风机可以在更窄的电机速度范围内提供更快的压力响应和期望的流量特性，从而导致更高的可靠性和较少的声学噪声。
