<b><i>Background:</i></b> Hypoxemia is a frequent adverse event occurring during flexible bronchoscopy and usually prevented by close monitoring and, if needed, oxygen supplementation nasal cannula. <b><i>Objective:</i></b> We aim to demonstrate that tracheal feasible, safe effective method restore saturation levels after desaturation. <b><i>Methods:</i></b> In first phase, we compare the or route in single blinded cross-over design healthy volunteers. second study patients referred for diagnostic bronchoscopy, who desaturate despite cannula, order assess ability correct hypoxemia through supplementation. <b><i>Results:</i></b> mean capillary partial pressure of was 181 mm Hg when at flow rate 4 liters/min administered route, compared 125 (p < 0.001). The carbon dioxide not significantly different. During 950 bronchoscopic procedures phase trial, 30 desaturated below 90% 22 out these patients, switching resulted correction within 120 s. remaining 8 were corrected increasing liters/min. After restoring levels, could be completed 25 patients. <b><i>Conclusions:</i></b> Tracheal safe, feasible an way bronchoscopy.
