Abstract

The system (10) and method for detect-ing disconnection and occlusion of a tubing system (16) of a patient ventilator (12) detects disconnection of the tubing system (16), opens the exhalation valve, delivers an idle flow of breathing gas to the tubing system (16), dis-ables breath triggering, and generates an alarm.
A reconnection of the tubing system (16) can also be detected, to initiate resumption of pres-sure supported inspiration. For occlusion de-tection, the pressure drop in the tubing system is determined by pressure sensors (26, 36) in the inspiratory and expiratory airways (20, 18) of the tubing system (16). The two pressure drop values are compared, and once occlusion is detected, an alarm is generated, and the ven-tilator (12) responds to protect the patient (14) from over distension. Abatement of the occlu-sion can also be monitored in a pressure based occlusion status cycling mode, and the ventila-tor (12) can revert back to normal ventilation when either circuit occlusion or exhaust port occlusion are not detected.
