Effect of freezing on exhaled breath condensate pH

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? ...

The effect of gas standardisation on exhaled breath condensate pH.

We have read with interest the American Thoracic Society/ European Respiratory Society Task Force document on exhaled breath condensate (EBC) [1]. EBC pH is emerging as a potential biomarker in respiratory disease. Gas standardisation (or deaeration) of EBC with argon is commonly performed to remove carbon dioxide prior to pH measurement [2–4]. It has been argued that CO2 is unwelcome ‘‘noise’’...

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...
