Lung mechanics before and after intravenous methacholine infusion. Resistance of the respiratory system (Rrs) was significantly increased and dynamic compliance (Cdyn) was significantly decreased, as measured in all animals (n = 18). The static compliance (Cst) was unchanged after methacholine administration, as measured in three pharmacologically paralyzed animals. *P < 0.05.
