Resp-O2™ Non-Rebreather Masks are designed to deliver high-concentration oxygen therapy in emergency and critical care settings. Each mask features a reservoir bag and a built-in safety valve to support consistent oxygen flow and minimize re-inhalation of exhaled air. The soft, transparent vinyl construction includes smooth edges, an adjustable nose clip, and an elastic head strap for a secure, comfortable fit. Select models include a universal connector compatible with a wide range of oxygen sources. Also available is a versatile 3-in-1 mask that functions as a medium-concentration, high-concentration, or non-rebreathing mask as needed.
