Exhaled breath condensate pH [PDF]

European Respiratory Journal, 2004
To the Editor: Vaughan et al. 1 are to be congratulated for the most extensive study of the pH of exhaled breath condensates (EBC) yet reported. However, there is reason to doubt that the pH of the condensate provides a reliable measure of the pH of fluid lining the airways.

Exhaled Breath Analysis Using Selected Ion Flow Tube Mass Spectrometry and Disease Severity in Heart Failure

Metabolites, 2023
Exhaled breath volatile organic compounds (VOCs) are elevated in heart failure (HF). The ability of VOCs to predict long term cardiovascular mortality and morbidity has not been independently verified.

On-Line Analysis of Exhaled Breath [PDF]

Chemical Reviews, 2019
On-line analysis of exhaled breath offers insight into a person's metabolism without the need for sample preparation or sample collection. Due to its noninvasive nature and the possibility to sample continuously, the analysis of breath has great clinical potential.

Tailored interventions based on exhaled nitric oxide versus clinical symptoms for asthma in children and adults [PDF]

, 2008
BackgroundThe measurement of severity and control of asthma in both children and adults can be based on subjective or objective measures. It has been advocated that fractional exhaled nitric oxide (FeNO) can be used to monitor airway inflammation as it ...
