Oxygen masks with reservoir bags are placed over the nose and mouth to deliver air of high oxygen concentration to a patient's airway. The device typically includes two unidirectional valves, one that closes during inspiration to prevent room air mixing with oxygen in a reservoir bag, and one that closes during exhalation to prevent exhaled respiratory gases from entering the reservoir bag. These masks are used for emergency oxygen delivery and treatment of hypoxia in patients requiring oxygen inhalation.
