Abstract
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.
