High frequency oscillatory ventilation has limited possibility of monitoring of intrapulmonary parameters. We have measured tidal volume during high frequency oscillatory ventilation by external monitor. The experimental circuit consisted of ventilator 3100 with its patient circuit, lung simulator 5600i and monitor Florian for measuring of tidal volume. Tidal volume was measured for different values of alveolar compliance that were set on the lung simulator. Measurement was repeated for ventilatory frequencies 3, 5, 7 and 10 Hz. Ventilatory parameters were held constant during the experiment. We have found that change of alveolar compliance has minimal effect on the delivered tidal volume.
