Lung diffusion estimated by oxygen and carbon monoxide.
The study was objected to the comparison of the results of lung diffusion estimated by oxygen to those of routinely used single breath carbon monoxide method. The method described is based on the analysis of the speed of response of arterial partial oxygen pressure (paO2) to increasing inspiratory fraction of oxygen (Fi). The transcutaneous oximetry was used to follow paO2 by means of transcutaneous oxygen pressure (ptCO2). The study was performed on 35 patients of both sexes with interstitial lung involvement with normal or only slightly decreased FVC and FEV1. The close correlation between the results of both methods was proved (r = 0.848, p < 0.0001).
