A respiratory therapy system comprising a respiratory therapy device configured to provide a breathable gas stream of at least a first pressure and a second pressure to a patient is disclosed. The respiratory treatment device comprises an airflow generator configured to provide a stream of respirable gas, a controller coupled to a trigger sensor configured to control operations of the respiratory treatment device, a breathing conduit assembly to deliver respirable gas to a patient via a patient interface, the trigger It includes a trigger that generates a signal that can be sensed by a sensor. The controller is configured to control the airflow generator to provide a breathable gas stream of at least a first pressure or a second pressure upon sensing a signal from the trigger. |
