Exhaled breath condensate pH.

A physiological-social score for triaging of pandemic influenza patients.

In summary, argon deaeration decreases the concentration and the variability of exhaled breath condensate partial pressure of CO2, but there is always some remaining CO2 that may still be a confounding factor in pH assessment. CO2 content has a marked influence on exhaled breath condensate pH and, since exhaled breath condensate partial pressure of CO2 varies even after deaeration, it leaves so...

Clinical Policy Bulletin: Breath Tests of Airway Inflammation: Exhaled Nitric Oxide and Exhaled Breath Condensate pH

Design and evaluation of a device for collecting exhaled breath condensate.

In recent years, the analysis of exhaled breath condensate samples has been given great weight as a noninvasive methodology of studying physiology and lung diseases. The present study describes a device for measuring exhaled breath condensate that is affordable, easily constructed, portable and suitable for use in the field, as well as allowing the collection of simultaneous samples. The result...

Identification of acid reflux cough using serial assays of exhaled breath condensate pH

BACKGROUND Chronic cough is a common problem, frequently caused or exacerbated by acid reflux. Diagnosis of acid reflux cough is haphazard currently, often relying on long therapeutic trials of expensive medications. We tested the hypothesis that the most relevant mechanistic component of acid reflux in chronic cough is when it rises to the level of the airway where acid can potentially be aspi...

Identification of Intrinsic Airway Acidification in Pulmonary Tuberculosis.

Exhaled breath condensate acidification reflects the presence of airway acidification. Mycobacterium tuberculosis is an organism particularly sensitive to acidity. We aimed to determine if there is evidence of airway acidification in a cross section of patients with active tuberculosis.We enrolled 51 subjects with active tuberculosis in Ghana and Thailand, and compared them to control subjects....
