Bronchial washing, punch biopsy and brush biopsy did contribute to hypoxaemia significantly. There was a uniform rise in heart rate in all the patients after FOB which was statistically significant. There was slight sinus tachycardia inmostofthecases although ECG indicated no major arrhythmias.ThepulmonaryfunctionswhichincludechangeinVC,FVC, FEV1andPEFR after FOB, on statisticallycomparisonnostatistical difference could be observed. Therewasnosignificantchangein PaCO2level and pH level.MeanofSBP andmeanofDBPwasstatistically significant.Conclusions:All patients showed a decline in arterial PaO2after FOB which was highly significant. There was slight sinus tachycardia in most of cases. FOB itself does not endanger the patients with any significant or serious complications.en_US
