Exhaled NO and exhaled breath condensate pH in the evaluation of asthma control

Exhaled breath condensate pH

In a previous issue of the European Respiratory Journal STEVENS et al. [1] suggested that preschool children with wheeze account for a significant proportion of the UK healthcare budget. Most preschool wheezing is caused by viral infection and, therefore, we wondered how much preschool children with upper respiratory tract infection (URTI) without wheeze would cost the National Health Service? ...

Exhaled breath condensate pH and exhaled nitric oxide in allergic asthma and in cystic fibrosis.

BACKGROUND It has been proposed that the pH of airway lining fluid may regulate the fractional exhaled concentration of nitric oxide (Fe(NO)) in respiratory disease. METHODS Fe(NO), exhaled breath condensate (EBC) pH, and EBC concentrations of nitrite plus nitrate (NO2/NO3) were compared in 12 subjects with stable asthma, 18 with stable cystic fibrosis (CF), and 15 healthy control subjects. E...

Exhaled Breath Condensate

Objective: To examine exhaled breath condensate levels of 8-iso-PGF2ot as a noninvasive quantification of pulmonary oxidant stress in patients with, or at risk for, ARDS/ALI. Methods: Breath condensate was collected from 22 patients with, or at risk for, ARDS/ALI by placing Tygon tubing submerged in an ice bath in line with the expiratory limb of the ventilator circuit. Ten patients without lun...
