Multicolored surface describing desflurane FA after 5 min for a 176 cm tall patient over the FGF - FD range studied. The FGF - FD combinations that result in a FAt of 4.5% (light blue surface) after 5 min are found by calculating the intersection between this target (the light blue surface) and the multicolored surface; these FGF - FD combinations are presented in B. The asterix (*) indicates the lowest possible FGF that can be used to attain 4.5% desflurane at 5 min because of the maximum 18% vaporizer setting.
