Pediatric oxygen mask

7900 Series Silicone Oro-(Mouth) Resuable Pediatric Face Mask & Mask Adpater for use with RESMON PRO FULL FOT SYSTEM. A face mask with adapter independently validated for use with the Res- mon Pro Full FOT device (FDA K152585). The Rudolph 7900 series face mask isolates the nose and allows only mouth breathing. An adapter, with a small round port extending to the patient, prevents the mouth from closing during testing. Only masks preventing nasal breathing provide comparable results to the conventional mouthpiece and nose clip setup. Mask straps and headgear are not required. The operator can hold the mask while collecting the few tidal breaths the Resmon Pro requires to complete the testing session. The Hans Rudolph Resmon Pro mask adapter requires an antiviral/antibacterial filter with a round outlet patient side.
