Intended Use:

The Hans Rudolph 7450 series V2 Mask face piece is designed for use with the Hans Rudolph Two-Way Non-Rebreathing Valves (NRBV) and other mask adapters designed for respiratory circuits with spontaneously breathing patients where the application requires a valve to separate the patient’s inspiratory and expiratory flows or a special connector to mate directly to a respiratory flow meter or other device. The typical mouthpiece and nose clip is replaced by this face mask assembly and headgear. The masks and valves are supplied clean, non sterile. Typical applications are for pulmonary function testing, exercise testing and respiratory research. These mask valves are classified as  reusable and can be high level disinfected.
