Influential factors and clinical significance of pH in exhaled breath condensate

Abstract

The technique of exhaled breath condensate is a new detective means for respiratory tract inflammation.It is more and more extensively applied in clinic because of the quick study abroad recently.However,the detectivc technique of pH is the most extensive one in exhaled breath condensate,and it is widely applied for asthma,chronic obstructive pulmonary disease,sleep apnea syndrome,lung cancer,pulmonary interstitial fibrosis,tuberculosis,bronchiectasis,cystic fibrosis and others.This article grasps the latest progress of relative study,reviews the influential factors of pH in exhaled breath condensate,including specimen collection,storage and detection,and the clinical application in the common diseases of respiratory system. Key words: Exhaled breath condensate; pH; Influential factor; Clinical application
