Visual presentation of model-based desflurane FA course in a fictive 176 cm tall patient. The multi-colored graphs (A) describe the predicted FA resulting from different FGF - FD combinations after 1, 2, 3, 4, and 5 min (bottom to top, respectively). The intersection of these surfaces with the FAt surface, in this example 4.5% desflurane (light blue horizontal surface), yields the corresponding FGF - FD combinations that attain that FAt (B). The asterixes (*) indicate the lowest possible FGF that can be used to attain 4.5% desflurane at 1, 2, 3, 4, and 5 min because of the maximum 18% vaporizer setting. More details are provided in the Appendix.
