Abstract
Background: Arterial hypoxaemia is the common complication, since respiratory depressant drugs are used for premedication, and the airway is also partially occluded by the bronchoscope. The study is therefore designed to nd out the changes in arterial oxygen tension and PEFR during FOB. Objectives: Ÿ To nd out the changes in arterial oxygen tension and in peak expiratory ow rate during FOB. Methods: 100 patients aged 20 years above undergoing FOB were evaluated for the arterial oxygen tension and peak expiratory ow rate changes at KNCH, Jodhpur. Results: All patients developed a fall in PaO2 following FOB but hypoxemia was noted only in 18 cases. The change in PEFR after FOB, no signicant statistical difference could be observed on statistically comparison. Conclusion: All patients showed a decline in arterial PaO2 after FOB which was highly signicant. FOB itself does not causes any signicant or serious complications.
