Abstract

Determination of transcutaneous PO₂ potentially offers a non-invasive method of determining arterial PO₂ in the presence of adequate skin perfusion. To investigate the extent and duration of hypoxemia in patients undergoing fiberoptic bronchoscopy, we measured the change of transcutaneous PO₂ in 14 patients during and after fiberoptic bronchoscopy. The results were as follows; 1) Mean P_tcO₂ was decreased from a prebronchoscopic value of 84.4 mmHg to 64.4 mmHg during bronchoscopy (11. 6 to 41. 4% from baseline ). 2) Change in P_tcO₂ during the bronchoscopic procedure was significantly related to duration of the procedure ( r = 0. 76 ). In conclusion, this study confirmed that bronchoscopic procedure cause a significant decline in PaO₂ and oxygen administration is recommended to prevent hypoxemia during bronchoscopic procedure.
