In one embodiment, mating portions 14,16 of the first and second chambers are configured as cylindrical portions ortubes, with the first chamber component 2 having an outer diameter shaped tofit within an inner diameter of the second chamber component 3. One or both ofthe chamber components are configured with circumferential ribs 18 and/or seals(shown in FIG. 1 on the first chamber component) that mate with the otherchamber to substantially prevent exhaled air from escaping from the chamberinterface. In one embodiment, the ribs 18 are spaced apart along the lengths ofone or both of the chamber components so as to allow the chambers to be movedlongitudinally in a longitudinal direction 20 relative to each other and thenfixed at different lengths depending on the location of the ribs 18 and amating shoulder 22 formed on the other chamber (shown in FIG. 1 as the secondchamber component). The rings, or ribs, and shoulder are preferably integrallymolded with the chambers, although they can also be affixed separately, e.g.,as an o-ring. It should be understood that various detent mechanisms, includingsprings, tabs, etc. can be used to index the first chamber component relativeto the second chamber component. Of course, it should be understood that thechambers can also be infinitely adjustable without any set detents, for examplewith a simple friction fit between the chamber components.

A valve cover 370 is configured with aspacer 372, configured in one embodiment for example and without limitationwith an oval or elliptical cross section, which passes through the center ofthe duck bill valve 320 so as to maintain the valve in a partially open state.The spacer 372, configured as a rod, is further configured with a passageway374, or safety hole, shown as a 2 mm hole, which allows the patient to alwayshave access to some atmosphere air if they completely empty the reservoir bagduring inhalation. This will avoid a total stoppage of inhaled air during thepatient's inhalation sequence due to an extra effort upon inhalation. Once thereservoir bag 306 is collapsed the patient will feel the resistance in thesystem through their breathing pattern and the patient will tend to stopinhaling and start to exhale.
