Evaluation of Exhalation Valves [PDF]
The Annals of Occupational Hygiene, 2005 Certification tests currently employed by some industrialized nations to certify respirators require that when challenged with air flow at a constant suction head of 25 mmH2O, the leakage into the facepiece from the exhalation valve(s) should not exceed 30 ml min(-1).

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.

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
