The most pronounced reduction in the partial pressure of the oxygen in alveolar air and its tension in the arterial blood in patients with dust diseases of the respiratory organs is observed when the clinically pronounced phenomena of chronic bronchitis are present. A significant increase in the alveolar-arterial gradient of the oxygen is noted, as a rule, during pulmonary deficiency of the third degree. The presence of the arterial-alveolar CO2 gradient was revealed, whose size, however, does not undergo substantial changes depending on the manifestation of the breathing deficiency.
