Abstract
A study were made of diagnosis and treatments of respiratory failure in advanced pulmonary tuberculous patients. Pulmonary function studies (including arterial blood gas determination) and E. K. G. were performed on 130 patients, arterial gas determination and E. K. G. were examined for evidence of respiratory failure in advanced 120 cases. Arterial gaseous tension were compared with ventilation, E. K. G. findings and other clinical symptomes as dyspnea or mental confusionetc.
The results were as follows:
1) Some factors of ventilation, as %VC, FEV 1.0/VC pred, and RV/TLC had a relationship with Pao2 and Paco2 level, but FEV 1.0% did not correlated with these parameters. And the cases of %VC lower as 60, or FEV 1.0/VC-pred lower as 40 and RV/TLC over 40 per cent showed abnormal value of arterial gaseous tension. E. K. G. findings also had a close relationship with respiratory failure.
2) Arterial blood gaseous determination were examined before oxygen therapy, and noteworthy facts were the modesty hypoxemia with severity of hypercapnea similar to obstructive lung diseases.
3) It is concluded that low flow oxygen administration with frequent monitoring of arterial blood gaseous is the better method of managing respiratory failure to prevent Cot narcosis in advanced tuberculous patients.
