Official Title: Evaluation of Gas Composition in the Oropharynx During High-flow Oxygen Therapy Through Nasal Cannula in Healthy Volunteers: a Physiological Study

Brief Summary: Observational, randomized studies and their meta-analyses have shown the high effectiveness of high-flow oxygen therapy through nasal cannulas, reaching 50-60% in acute hypoxemic respiratory failure.Some bench studies showed the advantages of high-flow oxygen therapy compared with standard oxygen therapy, consisting in reducing the anatomical dead space and maintaining a given inspiratory oxygen fraction in the hypopharynx of the mannequin, but the actual state of the gas composition of the hypopharynx was not…
