Abstract

A tubing assembly is disclosed for use between an exhalation valve and a ventilator for providing assisted breathing to a patient. The ventilator has a patient air outlet, a exhalation valve control outlet and a sensor outlet connected to a sensing mechanism. The exhalation valve has a first outlet to a tracheotomy connector, a second outlet to ambient atmosphere, an inlet and a control air inlet. The exhalation valve is switched between an inhalation position and an exhalation position by air pressure at the control air inlet. The tubing assembly comprises an exhalation valve connection, a ventilator-sensor connection, an intermediate tube, a sensor tube and an exhalation valve control tube assembly. The exhalation valve connection is attached at one end to the intermediate tube and at the other end to the inlet. The ventilator-sensor connection is attached at one end to the patient air outlet and at the other end to the intermediate tube. The sensor tube is connected at one end to the ventilator-sensor connection and at the other end to the sensor outlet. The exhalation valve control tube assembly is connected at one end to the control air inlet and at the opposite end to the exhalation valve control outlet whereby the ventilator controls the air pressure at the control air inlet. The exhalation valve control tube assembly extends through the exhalation valve connection, through the intermediate tube and through the ventilator-sensor connection.
