Exhaled NO and exhaled breath condensate pH in the evaluation of asthma control [PDF]

Respiratory Medicine, 2011
Asthma is a chronic inflammatory airways disorder. However, no biomarker of airways inflammation has been included in the assessment of asthma control.To evaluate exhaled NO (FeNO) and exhaled breath condensate (EBC) pH in patients with asthma according to the level of control, and their performance in the identification of not well-controlled patients.

Method development for measuring respirator exhalation valve leakage

, 1992
The wearing of respirators is an important means of protecting workers from excessive exposure to air contaminants. A proper-functioning exhalation valve is crucial for an effective respirator.

Collection of exhaled breath and exhaled breath condensate in veterinary medicine. A review [PDF]

Veterinary Quarterly, 2006
Collection of exhaled breath (EB) and exhaled breath condensate (EBC) is a noninvasive method for obtaining samples from the lower airways. While this technique has been well established for the diagnosis of lower respiratory tract diseases in human medicine, only a few studies have been performed in veterinary medicine. This article critically reviews

An Assessment of In SituRadon Exhalation Measurements, and the Relation Between Free and Bound Exhalation Rates

, 1992
By solving the diffusion equation for the axial-symmetric geometry of in situ radon exhalation measurements, the effect of the presence of the measuring device on the exhalation rate was determined.

Cytotoxicity of filtering respiratory protective devices from the waste sorting industry: A comparative study between interior layer and exhalation valve

Environment International, 2021
Filtering respiratory protection devices (FRPD) are mandatory for workers to wear in the Portuguese waste-sorting industry. Previous results regarding microbial contamination found on FRPD interior layer raised the question of whether microbial ...

Effect on Radon Exhalation Rate Due to Cracks in Concrete

Nordic Concrete Research, 2019
The second largest cause of lung cancer in the World is related to radon (222Rn) and its progenies in our environment. Building materials, such as concrete, contribute to the production of radon gas through the natural decay of 238U from its constituents.
