During operation of the microporous membrane oxygenators at some conditions, gas microbubbles penetrate into the blood. This effect, so-called spontaneous bubbling, takes place even when the blood pressure is higher than the gas pressure. This phenomenon was confirmed experimentally both in a model cell with hydrophobic microporous hollow fibers being used(More)

Three modifications of a stationary membranous oxygenator (SMO) with utilization of new selective compositional membranes were developed. Test procedures for the SMO in the system gas-gas and gas-blood on a stand and in acute experiments on animals are described. The results obtained demonstrated that as concerns the transport of oxygen and carbon dioxide,(More)
Univariate diffusion of oxygen and carbon dioxide through a selective membrane of a stationary membranous oxygenator (SMO) and moving blood film is considered. Through the use of a precise exponential approximation of the oxyhemoglobin dissociation curve [S (p)=1--ae-bp] a partial oxygen pressure distribution [p (x)] along the SMO membrane and a(More)
Mass transfer properties of the Soviet membrane oxygenator, MOCT, are tested. The liquid chambers of the oxygenator are made of disk membranes separating the moving blood from gas chambers. Processes of transportation and saturation of the blood film with oxygen are described by the simultaneous solution of the hydrodynamic and diffusion problem that is(More)
The efficiency of extracorporeal membrane oxygenation was studied for 2-3 hours in experiments on dogs with severe ventilatory respiratory failure. Extracorporeal oxygenation led to the decrease in arterial hypoxaemia and hypercapnia in animals. However, the variables did not reach the initial levels and were closer to normal values during veno-venous and(More)
The article considers the peculiarities and fields of application of the one-time membrane oxygenators MOST-1801 and MOST-1903 which are combined with heat exchangers and have a capacity of 100 and 500 ml/min respectively. The unified membrane elements employed in the design are used in the membrane oxygenator MOST intended for fully artificial blood(More)
