Exhaled breath condensate pH standardised for CO2 partial pressure

Exhaled breath condensate pH standardised for CO2 partial pressure.

Exhaled breath condensate (EBC) pH is considered to reflect the acid-base balance of the airways. Current pH measurements do not take into account the effect of CO2. The aim of the present study was to determine the effect of condensate CO2 partial pressure on pH and to provide a more precise mode of EBC pH determination. Condensate pH and CO2 partial pressure were measured in parallel from 12 ...

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

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...
