Bronchospirometric study was performed with ambient air and oxygen on 46 patients of pulmonary tuberculosis. Entire series were divided into three groups. The first group was consisted of 28 patients where bronchospirometry was made under air and oxygen breathing, alternatively. The test was made on ten patients of the second group where one lung breath air and the other oxygen. The third group was consisted of 8 patients where one lung breath air and the other oxygen following oxygen breathing of both lungs. 1) Decrease of oxygen uptake was marked under air breathing compared to in oxygen breathing in advanced cases of pulmonary tuberculosis. However, no constant changes in oxygen uptake were noted in moderately advanced and minimum cases. 2) Increase of ventiratory volume, respiratory frequency and minute volume were usually noted in the lung which breathes ambient air. Increase of minute volume is marked in the side of better functioning lung. 3) Respriatory equivalent increased in the lung which breathes air, especially marked in advanced and moderately advanced cases. 4) Vital capacity increased slightly in the side breathing air. 5) Bronchospirometry with air breathing can be performed without any undue burden on patients, if the test is limited in ten minutes, and give more precise information of pulmonary function of the affected lung than in ordinary bronchospirometry with oxygen.

1) Effects of surgical treatment of pulmonary tuberculosis, especially, lobectomy, thoracoplasty, extrapleural pneumothorax, segmental and partial resection on respiratory function were studied by bronchospirometry preoperatively andsix months postoperatively. Following results were obtained. 2) Effects on operated lung were most marked in thoracoplasty, and diminished in lobectomy, extrapleural pneumothorax and segmental resection in that order. It was minimum inpartial resection. 3) Decrease of respiratory function was exaggerated in cases where thoracoplasty was supplemented or pleural thickening developed following lobectomy compared to in cases without complications. 4) Decrease of vital capacity was most prominent in all the groups and decrease in oxygen consumption is in the second place. Decrease was minimum in minute volume. 5) In the contralateral lung, compensatory increaseof oxygen uptake and minute volume were noted though vital capacity decreased in all the groups. 6) Effects of extrapleural pneumothorax on respiratory function were variable. Some showed marked increase in ventiratory function, though marked decrease ensued in others.
