Philips Respironics | OptiChamber Diamond Valved Holding Chamber | Model 1077478

The Philips Respironics OptiChamber Diamond 1077478 is a premium anti-static valved holding chamber (VHC) engineered to optimize the delivery and lower-airway deposition of aerosolized medications from metered dose inhalers (MDIs). Constructed from an advanced anti-static polymer, the chamber prevents aerosolized particles from adhering to the interior walls, maintaining plume suspension for extended periods. This structural buffering eliminates the need for strict hand-breath coordination, ensuring a high fraction of respirable drug mass reaches the lungs while minimizing untargeted oropharyngeal deposition.
