A dual direction exhalation valve is disclosed herein. The exhalation valve includes first and second sealing discs which are each movably mounted within a housing. The first sealing disc includes at least one venting aperture that is initially obstructed by the second sealing disc. In response to an appropriate pressure force, the second sealing disc flexes or deflects such that the at least one venting aperture is exposed. Upon removal of the motivating pressure, the second sealing disc automatically returns to its initial, obstructive position. A method for venting gas from an inhalation system is also disclosed which utilizes a dual direction exhalation valve.
