Device allowing the filtration, sterilization, purification, refining and balancing of the temperature and humidity level of the inspired air, and allowing the sterilization of the expired air before release into the ambient air. The invention allows the aspiration of the ambient air, thanks to a ...
To study the behaviour of inspired aerosols in human conducting airways during breathholding, inhalation experiments were carried out using monodisperse ar... G Scheuch,W Stahlhofen - 《Journal of Aerosol Science》 被引量: 5发表: 1990年
sampled eNO using an online tidal breathing method at a fixed flow rate (controlled eNO) and in mixed expired air in 16 patients with asthma 7–14 y old and 51 pre- schoolers (14 healthy, age 2–5 y) and compared these tech- niques with eNOsb among school-age children only. They ...
. In addition, the difference was greater between the exhaled human breath samples and ambient air than between the exhaled human breath samples (Fig.6). Therefore, the specimens exhaled by humans included VOCs that emanate from alveolar breath and not only VOCs from the room air. Current limit...

The other gaso-transmitter, CO, is also present in exhaled breath and has two distinct sources: air pollution and tobacco smoke from the environment and the breakdown of heme to biliverdin from different cells in the body [17,22,137,138]. The reaction is catalyzed by heme oxygenase (HO) ...
Therefore, the analysis of some specific metabolites in the exhaled air can be used as evidence for diagnosing possible diseases in the human body [1,2,3]. The breath of a healthy person is primarily composed of nitrogen, carbon dioxide, unconsumed oxygen, and water vapor. For example, the...
