A flexible, form-shaped device designed to be placed over the nose and mouth to deliver a near-precise mixture of air and oxygen (O2) to a patient's airway without the use of a gas mixer. The device typically includes a variety of exchangeable inserts (the venturi) that allow air entrainment in controlled amounts to provide the desired O2 concentration. It is connected to an O2 source with tubing and includes headstraps for stabilization. Adaptors are typically included for connection to a humidification source. This is a single-use device.
