Fig. 1. Airway resistance (Rn), inertance (I), and tissue damping (G) and elastance (H) in children with normal airways ( open and cross-hatched bars with white background ) and with airway susceptibilities (AS , open and cross-hatched bars with gray background ) during propofol, and 13 min after sevoflurane and desflurane administration in children receiving either sevoflurane ( open bars ) or desflurane ( cross-hatched bars ) first. Data are mean ± SEM (n = 10 for each column). # P < 0.05, normal versus bronchial hyperreactivity for a given inhalation agent. § P < 0.05, sevoflurane (Sevo) versus desflurane (Des) within a group. *P < 0.05 versus propofol within a group.
