[External respiratory function of acute myocardial infarct patients following inhalation of pure oxygen].
Altogether 23 patients with acute macrofocal or transmural myocardial infarction were examined in the first 72 h of disease. Moderate clinical signs of circulatory insufficiency were noted in 4 patients. Ventilation and gas exchange indices of external respiration were recorded before and after 30 min. inhalation of 100% oxygen using a PGI-2 apparatus. 100% oxygen was shown to cause no toxic pulmonary injury, however it deteriorated the diffusion-perfusion in alveolar-capillary membranes. The type of the dynamic shifts of absorbed oxygen, minute respiration volume and oxygen utilization coefficient suggested the presence of 5 types of reactions, of them positive ones were thrice as less frequent as negative ones.
