Serial arterial blood gases were measured during fibreoptic bronchoscopy in 26 patients with diffuse interstitial lung disease. All those having transbronchial biopsy with or without bronchoalveolar lavage, performed breathing room air, showed significant falls in PaO2, at the time of passage of the bronchoscope through the vocal cords both at the beginning and end of the procedure. ⋯ Cessation of the supplementary oxygen 30 minutes after withdrawal of the bronchoscope did not result in rebound hypoxaemia. Bronchoalveolar lavage and transbronchial biopsy can be performed safely in patients with diffuse interstitial lung disease without significant hypoxaemia developing, if oxygen is started before the procedure and continued for 30 minutes after withdrawal of the bronchoscope.

Case Reports
'Atypical pneumonia' due to parakeet sensitivity: bird fancier's lung in a 10-year-old girl.
p6trinsic allergic alveolitis is rare in childhood, with most of the cases reported due to exposure to avian precipitins (Stiem et al. 1966; Dinda et al. 1969; Chandra & Everly Jones 1972; El-Hefny et al. 1980). We report a 10-year-old girl with bird fancier's lung, and suggest that environmental antigens should be sought in children presenting with non-resolving chest disease.
