  Introduction: While closed simple oxygen masks deliver oxygen at high flow rates, the actual FiO2 received varies. Open oxygen masks allow increased comfort for the patient, improved communication and feeding, and higher clearance of carbon dioxide, but may not deliver sufficient FiO2 at higher oxygen flow rates. This was an in vitro study of two open masks (Vyaire AirLife Open, Southmedic OxyMask) and two closed masks (simple oxygen mask, partial rebreather mask) at a variety of oxygen flow rates and tidal volumes in simulated normal and obstructive pulmonary states. Methods: We tested three sizes each of four different types of masks. Masks were applied to dedicated head models that had internal tubing to simulate the nasal and oral cavities. The masks were attached to an adjustable oxygen supply.. View more»
