FiO 2 cluster of minima of \(\overline{\Delta PaO}_{2}\) mean deviation with respect to PaO 2 /FiO 2-ratio for simulated data. Colored markers show the minima of the eight simulated data sets of Table 1 (numbered). Additional data were generated to visualize the curve progression and to confirm the findings (black markers). Minimum of \(\overline{\Delta PaO}_{2}\) mean deviation is shifted to a higher FiO 2 cluster for increasing severity of pulmonary impairment (lower PaO 2 /FiO 2-ratio)
