Figure 2.

Change in the proportion of patients with lung function alterations during hospitalization (dark grey columns) and at the follow up visit (light gray columns-6 weeks post-discharge). Restrictive pattern was considered the combination of a FEV₁/VC ≥ 100% predicted and a concomitant FEV₁ and VC < 80% predicted. DLco: lung diffusion capacity for carbon monoxide; FEV₁= forced expiratory volume in one second; KCO = transfer factor for carbon monoxide; VA = alveolar volume; VC = vital capacity.
