An improved device for providing a patient triggered breath to a patient including a ventilator having one tube that supplies a flow of a gas and another tube that delivers gas to an exhalation valve, an endo-tracheal tube that is in communication with the lungs of the patient, and a connector for connecting the supply tube from the ventilator to the endo-trachael tube. The connector has a chamber and a two-way check valve, the two-way check valve having an inhalation check valve and an exhalation check valve. The wall of the connector may further include an opening for connection to a pressure transducer. The volume of the chamber of the connector is between about 1.0 cm.sup.3 to 1.3 cm.sup.3 and the exhalation valve is selectively moved from its opened position to its closed position when the pressure transducer senses a reduction in pressure within the chamber of between about 0.25 cm of water and 2.0 cm of water and wherein the exhalation valve is moved from its closed position to it opened position after a predetermined amount of time.
