uses heated humidification for respiratory gas humidification, flows above 6 LPM have become possible without the associated discomfort, and with the added benefit of improving mucociliary clearance. Nasal high-flow therapy High flows of an air/oxygen blend can be administered via a nasal cannula to accurately deliver high volume of oxygen therapy. Respiratory gas humidification allows the high flows to be delivered comfortably via the cannula. Nasal high-flow therapy can be used as an effective alternative to face mask oxygen and allows the patient to continue to talk, eat and drink while receiving the therapy. Definition: Non-invasive delivery of oxygen air mixture delivered via a nasal cannula at flows that exceed the patient's inspiratory flow demands with gas that has been optimally conditioned by warming and humidifying the gas to close to 100% relative humidity at body temperature.
