Figure 2
Effect of several degrees of hypoventilation on F VRG during emergence. FVRG (partial pressure in the vessel rich group, representing the central nervous system) of desflurane (Figure 2 A), sevoflurane (Figure 2 B) and isoflurane (Figure 2 C) versus time after emergence with variable alveolar minute ventilation (VA). NV = normoventilation; HV = hyperventilation. Any FVRG data point that is above the thick horizontal line representing MACawake indicates rehypnotization.
