Patients with airway eosinophilia during an exacerbation of asthma had lower forced expiratory volume in 1 s (FEV1 ) and were more likely to require supplemental oxygen during admission than those without eosinophilia. This suggests that eosinophilic asthma exacerbations are more severe than non-eosinophilic exacerbations.
