[Valsalva's test in patients with bronchial asthma]
Abstract:
To examine feasibility of usage of phase IV hemodynamic alterations in the course of Valsalva's test in patients with bronchial asthma for detection of latent insufficiency of the right heart and pulmonary hypertension, 24 patients with mild bronchial asthma and 8 healthy individuals were subjected to Doppler echocardiography. The results indicate that this method is simple, well tolerated, can assess functional reserves of the lesser circulation. It can be used both for primary diagnosis and follow-up.

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.
