[Forced oscillation technique in the study of a bronchial response in patients with tuberculosis during drug test
Abstract:
A comparative study of the data obtained from the use of forced oscillation (FO) technique, spirography (SG), flow-forced expiratory volume (F-FEC) curve recording has provided evidence that the FO technique is highly effective in assessing a drug test. The FO technique revealed changes in bronchial patency in 69.5% of patients with bronchial obstruction whereas F-FEV recording indicated this pathology only in 42.4% (p < 0.05). A concurrent use of the pooled values of viscous respiratory resistance, SG, F-FEV curve to assess the results of a broncholytic test could diagnose bronchospasm in 79.7% of patients with pulmonary tuberculosis with impaired bronchial patiency.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
