Our objective was to compare HFNC therapy versus conventional oxygen therapy (COT) in the prevention of endotracheal intubation in this group of patients. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p> An open-label, controlled and single-centre clinical trial was conducted in patients with severe AHRF, defined by a PaO<jats:sub>2<\/jats:sub>\/FIO<jats:sub>2<\/jats:sub> ratio \u2a7d200, to compare HFNC with a control group (CG) treated by COT delivered through a face mask, with the need to perform intubation as the primary outcome. The secondary outcomes included tolerance of the HFNC device and to look for the predictive factors for intubation in these patients. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> A total of 46 patients were included (22 in the COT group and 24 in the HFNC group) 48% of whom needed intubation: 63% in the COT group and 33% in the HFNC group, with significant differences both in intention to treat [\u03c7<jats:sup>2<\/jats:sup>\u2009=\u20094.2; p\u2009=\u20090.04, relative risk (RR)\u2009=\u20090.5; confidence interval (CI) 95%: 0.3\u20131.0] and also in treatment analysis (\u03c7<jats:sup>2<\/jats:sup>\u2009=\u20094.7; p\u2009=\u20090.03; RR\u2009=\u20090.5; IC 95%: 0.3\u20130.9) We obtained a number needed to treat (NNT)\u2009=\u20093 patients treated to avoid an intubation. Intubation occurred significantly later in the HFNC group. Estimated PaO<jats:sub>2<\/jats:sub>\/FIO<jats:sub>2<\/jats:sub>, respiratory rate and dyspnea were significantly better in the HFNC group. Patients treated with HFNC who required intubation presented significant worsening after the first 8\u2009h, as compared with non-intubated HFNC group patients. Mortality was 22% with no differences. The HFNC group patients were hospitalized for almost half of the time in the intensive care unit (ICU) and in the ward, with significantly less hospital length of stay. A total of 14 patients in the HFNC group (58%) complained of excessive heat and 17% of noise; 3 patients did not tolerate HFNC. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> Patients with severe acute hypoxemic respiratory failure who tolerate HFNC present a significantly lower need for
