AquaVENT® heated breathing circuits combine technological advances in thermal conductivity and breathing circuit construction to deliver optimal and controlled humidification. Provision of high flow humidified oxygen therapy via nasal cannulae reduces CO2 rebreathing, decreases work of breathing, improves oxygenation through alveolar recruitment and causes less discomfort to the patient than low flow oxygen therapy. (1) BioCote® silver ion technology is used in the production of AquaVENT® to provide antimicrobial protection to patients and users. BioCote® reduces levels of viable pathogens on surfaces by over 99.6% and is effective against a range of microbes associated with hospital-acquired infections, including MRSA and Escherichia coli.
