Human exhaled breath condensation collection service

Breathing is an important physiological process in the human body, and the main component of exhaled air is water vapor, which also contains other gases and substances such as carbon dioxide. Exhaled breath condensate (EBC) is a liquid formed by rapidly and low-temperature (such as -5 ℃) condensation of exhaled breath with the assistance of an exhaled breath collection device.

From the source, exhaled breath condensate (EBC) is a lower respiratory tract lining obtained under non-invasive conditions. It is speculated that it is caused by the formation of a "cyclone" by respiratory airflow, which "scrapes off" the lining fluid in the airway, or by the tension formed by airway expansion during inhalation, which "tears apart" the surface liquid phase. EBC contains approximately 0.1% respiratory liner droplets and 99% water vapor, meaning that 1mL of EBC only contains 0.1 μ L of respiratory liner fluid. Therefore, EBC is a highly diluted matrix with extremely low content concentration. From the composition of exhaled breath condensate, its components are very complex, including various inorganic gases, volatile organic compounds, low volatility organic molecules such as aldehydes, fatty acids, and peptides, * (H2O2), inorganic salts such as nitrates, biomolecules such as proteins and nucleic acids, as well as bioaerosols containing bacteria, viruses, and fungi.

Human exhaled breath condensation collection serviceThe device is a portable and fast device for collecting exhaled breath condensate, suitable for patients undergoing spontaneous breathing and mechanical ventilation.

Air pollution, respiratory infections, smoking, inhalation of dust and chemicals, as well as genetic factors, can all lead to different diseases in the lungs and respiratory system, seriously threatening human life and health.

Exhaled breath condensate, like saliva, sputum, blood, sweat, and urine, is an important source of specimens for detecting various physiological and biochemical indicators in the human body. Exhaled breath condensate contains a large amount of volatile and non-volatile substances, and changes in these substances can reflect changes in the respiratory environment such as oxidative damage and inflammatory response, which can be used to detect changes in diseases.
