title: [Effect of hyperbaric oxygenation on central hemodynamics and oxygenating function of the lungs in open-heart surgery].
abstract: The dynamics of some oxygenating pulmonary function (OPF) indices has been studied in 33 patients with coronary cardiac disease and rheumatic lesions of cardiac valves 4-6 hours after surgery in response to a single hyperbaric oxygenation (HBO) session (1.5 ata, 45 min) in the immediate postoperative period. It is found that in the presence of slight or, on the contrary, pronounced arterial hypoxemia, no significant negative OPF changes were observed. At the same time, a temporary increase in the alveolo-arterial gradient has been found in some patients. The comparison of data on the systemic blood flow with the OPF indices permits suggesting the prevalent role of the membrane component in a PaO2 decrease in patients after using assisted circulation.
