Almost complete atelectasia was noticed in X-ray in the left lung. Fiberoptic bronchoscopy revealed a blood clot in the left main bronchus. Hypoxia and atelectasia improved immediately after removal of the blood clot. Obstruction due to clotted blood in the bronchus causing atelectasia after nasotracheal intubation should be kept in mind as a cause of intraoperative hypoxemia.trinfo:eu-repo/semantics/closedAccessAtelectasisBronchial ObstructionNasotracheal İntubationArticle1242952982-s2.0-11944265263N/A
