Time course of the mean end-tidal sevoflurane concentration for each group of runs. (a) Mean results for the runs during FGC in low and high FGF conditions when using both Primus® and Zeus® apparatus. (b) Mean results for the runs during AC with 1 and 6 litre min−1 FGF and during closed-circuit conditions when using the Zeus® apparatus.
