OptiChamber allows more respirable medication to be delivered to the patient. The anti-static material allows the aerosol to be suspended longer, giving the patient more time to inhale. Even under low pediatric pressures and flows, OptiChamber Diamond's inspiratory and expiratory valves open freely. OptiChamber's mouthpiece design helps patients transition from pediatric facemasks to mouthpiece. It also allows attachment to a 22 mm connector. The mouthpiece and adapter can be removed from the chamber for easy cleaning.
