Delivered tidal volume (VT) with various pressure amplitudes and oscillation frequencies in A: full-term infant settings and B: pre-term infant settings. Five ventilators were compared: Babylog VN500, Fabian HFO, Leoni Plus, SensorMedics, and SLE 5000, using the same mean airway pressure setting of 15 cm H2O and I:E of 1:1. Note that, at a frequency of 15 Hz under full-term infant settings, the Babylog VN500 was not able to increase the pressure amplitude beyond 36 cm H2O (white marker); under pre-term infant settings, the maximal pressure amplitudes delivered by the Babylog VN500 at 10 Hz and 15 Hz were 55 cm H2O and 33 cm H2O, respectively (white markers).

Tidal volume (VT) responses to change in oscillation frequencies, lung compliance, and resistance after activation of the volume-targeted mode in A: full-term and B: pre-term infant settings. Three ventilators were compared: Babylog VN500, Fabian HFO, and the Leoni Plus, using the same mean airway pressure setting of 15 cm H2O, I:E of 1:1, and the maximal setting for oscillatory pressure limitation. The VT target was set at 4 mL under full-term infant settings and 1 mL under pre-term infant settings. C = compliance; R = resistance
