Dynarex Resp-O2 Venturi Masks are designed to deliver oxygen at fixed concentrations ranging from 24% to 50%

Each mask includes 7 feet of kink-resistant, star lumen tubing to allow oxygen to flow freely. The transparent vinyl masks feature smooth edges, adjustable nose clips, and elastic straps for easy adjustment and a secure, non-binding seal. Masks are equipped with either color-coded dilutor jets or an adjustable dial for precise oxygen regulation.
