An experimental setup used to measure the fraction of exhaled nitric oxide (FeNO) in human breath samples. The subject blows into the tube (1) after a mouthpiece (2) has been connected to it. The wires on the side are part of the system that measures parameters like breath velocity, while the exhaled gas is taken to a FeNO analyzer (3).
Example Time of breath test-10:00pm...Result of breath test-0.080...Time of driving-9:00pm (stopped by officer)...Time of last drink-8:00pm...Last food-12:00pm. Using these facts, an expert can say the person's last drink was consumed on an empty stomach, which means absorption of the last drink (at 8:00) was complete within one hour-9:00.
Breath aerosol analysis consists in the sampling and analysis of particles emitted in the respiratory tract and present in exhaled breath. [12] This is a relatively new field that holds great promise for direct diagnostics of pathogens, such as Influenza , and for in-vivo monitoring of the respiratory lining fluid ( Respiratory epithelium ...
Breathalyzer – by far the most common usage of this term relates to the legal breath test to determine if a person is driving under the influence of alcohol. Hydrogen breath test – it is becoming more and more common for people to undertake a medical test for clinical diagnosis of dietary disabilities such as fructose intolerance , fructose ...

For example, it was believed that the exhaled breath of a diabetes person presented a sweet odor, while for people affected by kidney failure it showed a fish-like smell. [5] Only with Antonie Lavoisier , the pure smelling of human exhaled breath was substituted by a systematic analysis of the chemical contents.
The respiratory quotient (RQ) is the ratio: RQ = CO 2 eliminated / O 2 consumed. where the term "eliminated" refers to carbon dioxide (CO 2) removed from the body in a steady state.
Inventor of the Breathalyzer Robert Frank Borkenstein (August 31, 1912 – August 10, 2002) was an American inventor, researcher, and professor. He is best known for inventing the breathalyzer , a device that is used to detect a person’s alcohol content from their breath.
