Predicting effective continuous positive airway pressure.

abstract：BACKGROUND:Characterizing acute exacerbations of COPD (AECOPD) and individualizing therapy is challenging. Key exacerbation therapies include antibiotics and systemic corticosteroids. Blood eosinophils, when either low or high, may offer a simple, inexpensive distinction to predict beneficial responses to these therapi...
