Flowcharts of model simulation (left) and model identification (right). In model simulation, blood gas levels are calculated with respect to FiO 2. Model parameters f s and f A are known. Vector Θ summarizes parameters as well as other physical constants necessary for model calculation. Model identification process \(\tilde{M}_{\alpha }\) minimizes an objective function for measured blood gas levels at a specific \(\widetilde{FiO}_{2}\). Identified parameters are f * s and f * A
