Sevoflurane Wash in Method Using Conventional Flows Versus Low Flows of 0.5L

The time of reaching FAS=2% will be noted in both the groups. The time taken in seconds from Tzero to reach FAS 2% (Ttarget) will be calculated. Inspired concentration of Sevoflurane (FIS), FAS, and age-adjusted MAC will be retrieved from the automatically recorded 'trend' of parameters. FIS, FAS and age-adjusted MAC will be noted every 30 sec. starting from Tzero, till T5 and every minute thereafter until T15.
