Association of Peak Expiratory Flow with Pulmonary Fungal Infection in Hospitalized Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Single-Center Retrospective Study

Objective

Pulmonary fungal infections are increasingly recognized as important complications of acute exacerbations of chronic obstructive pulmonary disease (AECOPD), but early identification remains challenging. This study investigated the independent association between peak expiratory flow (PEF) and pulmonary fungal infection in hospitalized patients with AECOPD.
