Abstract

THE EFFECTS OF AIRWAY RESISTANCE AND ALVEOLAR COMPLIANCE UPON DELIVERED TIDAL VOLUME DURING HIGH FREQUENCY OSCILLATORY VENTILATION. Mechanical lung ventilation is used for a delivery of the oxygen into the organism and removal of carbon dioxide from the organism in cases where the spontaneous breathing of the patient is inhibited or insufficient. High-frequency oscillatory ventilation is quite different from conventional regimens of mechanical ventilation. High-frequency oscillatory ventilation is used mainly for the patient with evere acute respiratory distress syndrome, however concrete target group of the patient is not clearly defined. The model of hte lungs according to its morphological description is designed for studying of the high-frequency oscillatory ventilation. The effect of the mechanical properties of the lungs,airway resistance and alveolar compliance upon the delivery of tidal volume is studied for high-frequency oscillatory ventilation. Resistance of the airways significantly affects the tidal volume in high-frequency oscillatory ventilation whereas the effect of the descrease of the alveolar compliance is almost negligible.
