Left clustered mean deviation of \(\overline{\Delta PaO}_{2}\) over FiO 2 for simulated data. Deviation of prediction of PaO 2 depends on FiO 2 range used for model identification. Broken lines show respective minima for the different data sets (numbered). Minimum is located at a higher FiO 2 range for data representing a higher pulmonary distress. Right mean of ΔPaO 2 over FiO 2 for real patient data. Deviation of prediction of PaO 2 varies with the FiO 2 level used for model identification. The location of the minimum depends on patients’ pulmonary state. Mean deviation of ΔPaO 2 was less than 10 % at the minimum for both data sets
