  1. Data are presented with mean ± standard deviation
  2. ABG Arterial blood gas, PaCO2 Arterial partial pressure of carbon dioxide, PaO2 Arterial partial pressure of oxygen
  3. † Reported p value from two-tailed paired Students t-test (n = 5 rabbits, α = 0.05) of the ABG measurements from 30 min of ventilation with either the Carestation or FALCON
  4. ‡ Reported p value from either the paired Students t-test (PaCO2, pH and lactate) or Wilcoxon signed-rank test (PaO2) of ABG measurements from 60 min of ventilation with either the Carestation (n = 4 rabbits due to unanticipated inaccessibility of the ABG machine for one rabbit’s sample) or FALCON (n = 5 rabbits, α = 0.05, unpaired data point was ignored in the calculation)
  5. *p < 0.05, **p < 0.01
