Jet high-frequency artificial ventilation produces oscillations of some parts of the chest wall, which in its turn transmits oscillations to the lung parenchyma. It results in the mix-up of the gas in the alveolar space, which leads to the increase in the gradient of oxygen concentration on the alveolar membranes, thus, augmenting oxygen saturation of the blood. The effect is the same when oscillation artificial ventilation is performed, owing to the provocation of the oscillations amplified by the resonance in the natural acoustic circuit, formed by the adjacent parts of the chest and lung parenchyma.

A total degree of ventilation irregularity in the CHD patients did not differ from that of healthy individuals. An increase in this index was noted for the right lung in all the patients.
