Left clustered mean deviation of \(\overline{\Delta PaO}_{2}\) over \(PaO_{2,meas}^{j}\) for simulated data. Minimum in prediction error of PaO 2 data is in the range of 150–200 mmHg for data sets 1–7. Because of the high severity of pulmonary impairment, data sets 8–12 do not achieve this oxygenation range, even when a FiO 2 of 100 % is applied. Right mean of ΔPaO 2 over \(PaO_{2,meas}^{real}\). Real patient data tested in our study confirm the curve progression of the study with the simulated data. The best prediction performance is shown for identification in the PaO 2 range of 70–80 mmHg
