A flow of gases in a respiratory therapy system can be conditioned to achieve more consistent output from sensors configured to sense a characteristic of the flow. The flow can be mixed by imparting a tangential, rotary, helical, or swirling motion to the flow of gases. The mixing can occur upstream of the sensors. The flow can be segregated into smaller compartments to reduce turbulence in a region of the sensors. 在种呼吸治疗系统中的气体的流动可以被调节成实现多个传感器更致的输出，这些传感器被配置成感测流动的特性。可以通过为气体的流动赋予切向、旋转、螺旋、或涡流运动来使流动混合。该混合可以发生在这些传感器的上游。该流动可以被隔离到较小的隔室中以减少在这些传感器的区域中的紊流。
