OptiChamber® Advantage Valved Holding Chamber

Please check with your local Respironics Representative to find out if this product is available for purchase in your country.


OptiChamber Advantage Valved Holding Chamber was designed to optimize delivery of metered dose inhaler (MDI) asthma medication. OptiChamber makes available more of the smaller medication particles — those that can reach deep into the peripheral airways — than the smaller (AeroChamber® 145 ml) valved holding chamber developed in the early 1980s.¹-² And, OptiChamber has been clinically demonstrated to provide rapid lung function improvement when compared to drug delivered via jet nebulizer and a large volume (Volumatic®, 750 ml) spacer³. Designed to optimize patient value and ease-of-use, OptiChamber's replaceable valve facilitates cleaning and provides longer trouble-free performance. In addition, detachable masks adapt to changing patient needs and help keep costs to a minimum.
