Effects of fresh gas flow, tidal volume, and charcoal filters on the washout of sevoflurane from the Datex Ohmeda® (GE) Aisys®, Aestiva®/5, and Excel 210 SE Anesthesia Workstations

Conclusion The GE AWSs should be purged with large FGFs and VTs ~350 mL·breath−1 for ~25 min to achieve 10 ppm sevoflurane. The FGF should be maintained to avoid a rebound in anesthetic concentration. Charcoal filters rapidly decrease the anesthetic concentration to < 2 ppm.
