What Researchers Did
Researchers investigated the efficacy of combined drug treatment, hyperbaric oxygenation, hypobarotherapy, and artificial speleotherapy in 84 patients with dust-induced bronchitis.
What They Found
Among 84 patients, artificial speleotherapy demonstrated the highest efficacy, significantly improving cardiopulmonary functional indices. Hypobaric regimen showed the second highest efficacy, while hyperbaric oxygenation was found to be of low efficacy.
