Figure 3. Pulmonary function tests: (A) Parameters 20 days after discharge showing normal values of dynamic and static volumes of capacities, a negative bronchodilator test (red in the charts), an increase in residual volume (RV) absolute and relative to total lung capacity (TLC), suggesting airway obstruction not observed in spirometry, and a normal carbon monoxide (CO) diffusing capacity; (B) Prebronchodilator values 7 months after discharge with normalization of RV and a normal CO diffusing capacity. FVC – forced vital capacity; FEV1 – forced expiratory volume in 1 second.
