Described is a respiratory therapy system that includes a respiratory therapy device configured to provide a flow of breathable gas to a patient at at least a first pressure and a second pressure. The respiratory therapy device includes: a flow generator configured to provide a flow of breathable gas; a controller coupled to a trigger sensor for controlling operation of the respiratory therapy device; a breathing catheter assembly for delivering breathable gas to a patient through a patient interface; generating A trigger that can be triggered by a signal detected by a sensor. A controller is configured to control the flow generator to provide the flow of breathable gas at at least a first pressure or a second pressure based on detecting a signal from the trigger. |
