|×103 cells/μL, *neutrophils.|
PE: pulmonary edema; IVM: increased vascular markings; Miss.: missing.
O: obstructive pattern; R: restrictive pattern; M: mixed pattern; U: undetermined pattern.
£Obstructive pattern: FEV1/VC ratio below LLN; Restrictive pattern: TLC below LLN or FEV1/VC ratio ≥ 85% and a reduced VC; mixed: FEV1/VC ratio and TLC below LLN.
¥Obstructive pattern: mild: FEV1/FVC ratio < 70%, FEV1 ≥ 80% of predicted, moderate: FEV1/FVC ratio < 70%, FEV1 ≥ 50%–< 80% of predicted, severe: FEV1/FVC ratio < 70%, FEV1 < 50% of predicted; restrictive pattern: FEV1/FVC ratio ≥ 70% and FVC < 80% of predicted.
$Obstructive pattern: FEV1/FVC ratio ≤ 0.70 and normal, reduced, or increased FEV1 and FVC percent predicted; restrictive pattern FEV1/FVC ratio ≥ 0.75, FEV1 and FVC < 75% of predicted; mixed: FEV1/FVC ratio > 0.70 and < 0.75 FEV1 and FVC < 75% predicted.
