Figure 1From: Desflurane consumption during automated closed-circuit delivery is higher than when a conventional anesthesia machine is used with a simple vaporizer-O2-N2O fresh gas flow sequence End-expired desflurane concentrations (F A , %) with the vaporizer-fresh gas flow sequence (ADU group) or with automated closed-circuit anesthesia (Zeus ® group). Results are presented as mean ± standard deviation.Back to article page
