Fig. 4

Arterial blood gas parameters during hypoxia and hypercapnia with normal mechanical ventilation (CMV, open symbols on the left), during high-frequency percussive ventilation (HFPV, blue filled symbols on the right) and during expiratory high-frequency percussive ventilation (eHFPV, red filled symbols on the right). Characters in the legend denote the oscillatory amplitude (2 or 4 cmH2O), the superposed frequency (5 or 10 Hz), and its application phase (E: expiratory phase only; IE: entire breathing cycle). PaO2: arterial partial pressure of oxygen, PaOC2: arterial partial pressure of carbon dioxide, SaO2: arterial oxygen saturation. *p < 0.05 between HFPV or eHFPV vs. the corresponding CMV
