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 some uncertainty in the exhaled breath condensate pH reading even after deaeration. It seems worthwhile to carry out some more research to define other potential modes of standardisation of this measurement, to learn more about the different factors that may influence exhaled breath condensate pH and the relationship between the pH of exhaled breath condensate and that of the airways.
