FIELD: medicine.
SUBSTANCE: invention concerns medicine and can be used in treating the diseases accompanied with chronic tissue hypoxy. That is ensured by breathing of hypercapnic respiratory mixture created by the patient by mixing the proper exhaled and atmospheric inhaled air in a respiratory device representing a mixing chamber mask of capacity 0.8 litres. A mask is put on to the patient's face with embedding nose, mouth and chin and fixing so that to ensure free breathing, and adjusting the gaps the face and mask, herewith preventing air drags. A mask is individually matched for each patient depending on the rest exhalation volume. Its capacity shall be 100-150%, and dimensions shall not impede sight and head movements of the patient. The mask breathing is continuous to enable normal ventilation indicated by improved health state and achieved time of after-exhalation rest breath-holding 40-60 seconds.
EFFECT: method allows for considerable reduction of chronic tissue hypoxy due to continuous inhalation of the hypercapnic mixtures regardless of the environment.
