A respiratory apparatus for providing respiratory support to a patient comprising a nasal interface and a gas conduit 400 for delivering a flow of gases to an outlet of the nasal interface. The apparatus comprises a device and/or a sensing arrangement adapted to configure the apparatus between a first configuration for providing a first level of the flow of gases to the outlet and a second configuration for providing a second level of the flow of gases to the outlet. The second level is less than the first level and the device and/or the sensor arrangement is located to the nasal interface or at near to a patient end of the conduit. The device may comprise a collapsible portion 402 of the gas conduit configured to transition between the first and second configuration. |
