FIG. 7.

Specific ventilation maps of a 15 mm sagittal slice of the right lung (same as in Fig. 6, mild asthmatic, bottom row), showing the time course of recovery following methacholine-induced bronchoconstriction (1 mg/mL) in a mild asthmatic. A 7-minute overlapping sliding window approach, centered at 15, 20, and 25 minutes after methacholine was applied, opening a window into the dynamics of the recovery from an induced asthma challenge.
