[Pulmonary function and artery blood analysis of diabetes mellitus].

The widespread and depth-in investigations on the pulmonary change in DM have been documented abroad. Some revealed that the abnormalities of pulmonary function usually exist in DM. There has been no similar report found in China so far. In this study, ventilation, small airway function (V25 and V50), diffusion capacity and artery blood gas studies have been done in 60 DM and 62 healthy subjects respectively. The results have shown that there is a significant difference between NIDDM group and control group (P less than 0.05) in V50, V25, DLCO and the reduced value of PaO2, and there exists remarkably significant difference between the IDDM group and control group (P less than 0.01) in the decreased values of TLC, FEV1.0%, V50, V25, DLCO, PaCO2 and PaO2.
