Examination of 76 patients with pneumoconiosis (stage I) revealed that hyperbaric oxygenation is increasing the force of cardiac contractions, reduction of the general peripheral resistance and reduction of the lesser circulation hypertension. The therapeutic action of hyperbaric oxygenation is related to its ability to remove the sequels of oxygen.
