The water in the nebulizer of respirators is a potential source of infection for patients receiving artificial respiration. Interposition of a special equipment that will produce ozone-free ultraviolet radiation will prevent infection of the patient by the inspired humidified air, even if the bacterial count in the nebulizer fluid is very high. Interposition of the same equipment on the expiratory side is also recommended to minimize the risk of infection of the environment by bacteria in the expired air.
