These masks, sometimes called High Air Flow Oxygen Enrichment (HAFOE) masks incorporate a Venturi Barrel and use the Bernoulli principle to deliver a predetermined and fixed concentration of Oxygen to the patient, regardless of the patients respiratory pattern, by providing a higher gas flow than the peak inspiratory flow rate. Due to the exhalation holes on the mask, expired gas is flushed out resulting in minimal rebreathing and little increase in dead space.
The performance of small Venturi Masks is not to be considered to be as accurate as large volume masks. The concentration is very much dependant on patients breathing rate and minute volume.
