No, the chamber and mask combinations are specifically designed to optimize medication delivery for the individual need of each patient. The small and medium chambers have inspiratory valves that are specifically designed for lower flow rates, so they open easily for infant or pediatric patients especially when tidal breathing. The intermediate and the large chambers are also equipped with the FLOWSIGNAL® Whistle to alert the user when they are inhaling too quickly and to encourage slower deeper breaths.
The AEROCHAMBER PLUS® FLOW-VU® Chamber should be replaced every 12 months. However, you should replace it if any of the following occur (1) The valves are missing or damaged. When this happens, the chamber cannot work properly and must be replaced. (2) The backpiece becomes cracked or torn. This may affect the amount of drug that is breathed in. (3) The mask does not comfortably fit the face. It may be time to use another model with a larger mask or use the AEROCHAMBER PLUS® FLOW-VU® aVHC with mouthpiece.
The majority of adults do not use their inhalers properly. Up to 80% of people have poor inhaler technique which can lead to asthma attacks and poor outcomes.1 Chambers help by making it easier to inhale your medication and helping to ensure the inhaler medication is delivered to your lungs, where it is needed. 1.
