title: [The role of acoustic resonance in realizing the effect of high-frequency artificial ventilation of the lungs].
abstract: A new explanation of improved oxygenation during high-frequency jet ventilation has been suggested. The mechanism is based on resonance oscillations generated by oscillation and injection high-frequency jet ventilation and promoting gas penetration into the alveoli, PaO2 elevation in perimembrane layer and O2 concentration gradient increase between the alveolar and convection zones. Alveolar and bronchial fluctuations facilitate their drainage and decrease pulmonary shunting. The suggested mechanism is explained, using facts known from the practical application of high frequency jet ventilation. The advantages of combined volumic-oscillation high-frequency jet ventilation over the jet one are established, except cases of lung ventilation in patients with open bronchus and in patients transmitted to spontaneous respiration after prolonged controlled lung ventilation.
