Respiratory therapy system and apparatus

A respiratory therapy system, the respiratory therapy system comprising:

• a respiratory therapy apparatus, configured to provide a flow of breathable gas at, at least a first pressure and a second pressure to a patient, the respiratory therapy apparatus comprising;
• a flow generator configured to provide the flow of breathable gas,
• a controller, coupled to a trigger sensor, to control respiratory therapy apparatus operations;
• a breathing conduit assembly that conveys the breathable gas to a patient via a patient interface;
• a removably connectable trigger, configured to be actuated from a position remote from the patient interface, that produces a signal detectable by the trigger sensor;
• a connector element disposed between the breathing conduit assembly and the patient interface;
• a removably connectable trigger that is removably attached to the connector element, the trigger configured to be actuated from a position sufficiently remote from the connector element to allow a first person to hold the patient interface in place over a patient's mouth and/or nose, and a second person to control actuation of the trigger, that produces a signal detectable by the trigger sensor;
• wherein the trigger comprises a pneumatic compressible chamber integrated with the breathing conduit assembly;
• wherein the controller is configured to:
• maintain positive end expiratory pressure (PEEP) as a baseline therapy pressure;
• detect a compressible-chamber pressure exceeding a predefined threshold indicative of user actuation;
• and
• in response, temporarily deliver peak inspiratory pressure (PIP) for a duration of trigger actuation, automatically reverting to PEEP upon release of the trigger;
• and
• wherein the trigger does not modify stored therapy parameters.
