What is a valved holding chamber ("VHC")?
Valved holding chambers are devices designed for use with metered-dose inhalers (MDI). Their purpose is to improve medication delivery, decrease deposition of medication in the mouth and throat, and eliminate the need to coordinate activating the MDI with inhaling the medication.
Holding chambers keep the medicine suspended in the chamber until the patient is ready to inhale. It therefore reduces the need for hand breath coordination. As a result, there is improved medication delivery with a decrease in oral drug deposition.
