Fisio Chamber Vision Anti-Static Asthma Inhaler Chamber. Fisio Chamber Vision is an anti-static device designed to be used with metered dose asthma inhalers to enable the patient to inhale the optimum amount of drug. The problem with some metered dose inhalers is that if the patient does not inhale at the correct moment or if they have difficulty taking a long, deep breath, some of the drug can dissipate into the air rather than being inhaled.
