Insertion of a nasopharyngeal tube (NT) is a highly effective approach to the management of acute hypox­aemia during flexible bronchoscopy (FB) in lung ­transplant recipients. We noted that lung transplant recipients undergoing FB who had been treated previously with NT insertion had further episodes of oxygen desaturation (<90%), despite supplemental oxygen therapy. Prophylactic NT insertion prevented acute hypoxaemia in the majority of lung transplant recipients, with previously documented FB-related oxygen desaturation secondary to UAO. Additional jaw support may be needed in some patients with severe upper-airway obstruction. (Intern Med J 2003; 33: 317−318)
