[Use of hyperoxic mixtures for diagnosing latent disturbances in the external respiratory system].
Blood gases, acid-base balance and the magnitude of the alveolocapillary gradient were studied in normal persons and in patients with chronic non-specific lung diseases breathing gas mixtures at PiO2 160--230--300--460--700 mm Hg. A graphic method was suggested for evaluating lung gas exchange disturbances by comparing PAO2 and PAO2.
