A<unk>  is a device used to increase the ease of administering aerosolized medication from a metered-dose inhaler (MDI). It adds<unk> in the form of a tube or “chamber” between the mouth and canister of medication. Most<unk> s have a one-way valve that allows the person to inhale the medication while inhaling and exhaling normally; these are often referred to as valved holding chambers (VHC). AeroChamber, InspirEase and Volumatic are examples of a<unk> .<unk> s help those unable to breathe deeply, as well as those unable to synchronize their breathing so that they inhale just as the MDI is actuated; the latter is known as poor "hand-lung coordination". __TOC__
