Fig. 1. Time course (in minutes on the x-axis) of changes in peak inflating pressure (PIP;top ), peak expiratory flow rate (PEFR;middle ), and dynamic compliance (C^dyn;bottom ) after administration of rapacuronium. The baseline measurements are labelled as time 0. Statistically significant changes in PIP, PEFR, and C^dynoccurred after administration of rapacuronium (see also table 2).
