Median (interquartile range). COPD grade is defined as follows: mild-to-moderate COPD, FEV1 ≥50% predicted with FEV1/FVC <0.7; severe-to-very severe COPD, FEV1 <50% predicted with FEV1/FVC <0.7. Restrictive disease is defined as FVC <80% predicted with FEV1/FVC ≥0.7.
Abbreviations: COPD, chronic obstructive pulmonary disease; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; ICU, intensive care unit.
