Abstract
In 171 cases of pulmonary tuberculosis, the acid-base balance was measured by the micro-method of Astrup, showing the data in many cases within the normal range. —But the % VC had a close realationship with acid base. —In cases with to VC lower as 50, the blood pH became always lower; in case with these two tendencies the FEV1.0 remained of ten under 30. -In cases with % VC lower as 60, the PCO2 showed a wide distribution of values: In cases with % VC lower as 50, extremely high values of PCO2 were observed; three cases with %VC lower as 30 showed the PCO2 higher than 40mmHg. -In cases with %VC lower than 60, the buffer base mostly showed high value; in 32 cases lower than 50 of %VC, the latter showed the value higher than 48mEq/l in 26-(81). -Regarding the significance band in chronic hypercapnia of Schwartz, the cases with %VC lower than 60 remained more frequently as the cases higher than 60.
