Representative flow (a) and pressure (b) waveforms generated by the Carestation (green line) and FALCON (orange) sampled over 10 s. VT (c), ΔPIP (d), ΔPEEP (e), RR (f), and I:E ratio (g) derived from the average of 1-min samples taken every 10 min for the duration of ventilation are shown for the Carestation (green) and FALCON (orange). ΔPIP calculated as ΔPIP = PIP − PIPtarget, and ΔPEEP calculated as ΔPEEP = PEEP − PEEPtarget. Either two-tailed paired Students t-test (VT, ΔPIP, ΔPEEP, and I:E ratio) or Wilcoxon signed rank test (RR) were performed (n = 5 rabbits, α = 0.05). ****p < 0.0001, I:E inspiratory time to expiratory time, NS not significant, PEEP positive end expiratory pressure, PIP peak inspiratory pressure, RR respiratory rate, VT tidal volume
