FVRG during emergence. FVRG (partial pressure in the vessel rich group, representing the central nervous system) of desflurane (DES), sevoflurane (SEVO) and isoflurane (ISO) versus time during emergence with normoventilation (NV) and hyperventilation (HV). The first data point is the value of FVRG at the moment FA (partial pressure in the alveoli) reaches 0.3 MAC (MACawake).
