Figure 4.

Arterial oxygen partial pressure (PaO₂) during different oscillatory frequencies with the arteriovenous extracorporeal lung assist device (ECLA) opened and closed. After lung recruitment and switching ventilation to HFOV the PaO₂ was significantly higher compared with lung injury (T_ARDS) (§p < 0.05). PaO₂ remained significantly improved with rising oscillatory frequencies compared with T_ARDS (§p < 0.05). The PaO₂ was significantly increased at 15 Hz with the ECLA opened (* p < 0.05).
