defined as the time beginning from first recorded fraction inspired sevoflurane concentration until any one of the following recorded times – (a) peripheral venous cannula insertion or first recorded intravenous medication administration, (b) anesthesia “ready” indicated by the provider, or (c) securing of the airway (e.g. LMA insertion or endotracheal intubation) – whichever came first.
