呼气检测技术与设备的研究进展

s an important physiological process for human beings, breathing is one of the most important ways to exchange substances between the human body environment and the outside world. Various studies suggested that the type and concentration of the exhaled breath that contains a large number of metabolic products, have closed relationships with human health. Nitric oxide, one kind of exhaled gas, is an internationally recognized molecular markers of airway inflammation. Through detecting the exhaled markers, we can promptly detect the body's health condition, and monitor the occurrence and development of disease, so as to achieve the purpose of disease prevention. Due to the non-invasive, exhaled breath detection technology and equipment emerged in large numbers both at home and abroad.
