Smaller-than-expected concentrations of sevoflurane were delivered by Sevotec 5® vaporizers (Datex-Ohmeda, Madison, WI) at low-fill states, 8% dialed concentrations, and high fresh gas flows. Clinically, this would lead to prolonged induction times. The risk of complications from prolonged inhaled induction could be increased when using a vaporizer with these characteristics.
