Description

A non-rebreather oxygen mask is a medical device used to deliver high concentrations of oxygen, primarily in emergency situations. It consists of a face mask connected to a reservoir bag filled with oxygen, which allows the patient to inhale oxygen from both the bag and the direct oxygen source. It鈥檚 a face mask that fits over your mouth and nose. An elastic band stretches around your head to keep the mask on. The mask connects to a small bag filled with oxygen (reservoir bag), and the bag is attached to an oxygen tank. It provides a high concentration of oxygen quickly, typically in a hospital or emergency room, or in an ambulance during transportation to a hospital. The main feature of a non-rebreather mask is that it has several one-way valves. The valves prevent you from 鈥渞ebreathing鈥 any exhaled air or room air. You鈥檙e only inhaling oxygen directly from the reservoir bag and oxygen tank, with no outside air diluting the oxygen.
