Expired Breath Hydrogen Peroxide Is a Marker of Acute Airway Inflammation in Pediatric Patients with Asthma

Airway inflammation is important in the development and progression of many pulmonary disorders, including asthma. We hypothesized that the hydrogen peroxide (H2O2) concentration in expired breath may be a marker of airway inflammation. Expired breath condensate was collected by cooling and the H…
