    Breath CO monitor displaying carbon monoxide concentration of an exhaled breath sample (in ppm) with its corresponding percent concentration of carboxyhemoglobin. When dealing with CO, time is critical. In the blood stream carbon Monoxide has an affinity with hemoglobin some 200 times greater than oxygen.

    Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...

    The air quality in Mexico City is reported in IMECAs. The IMECA is calculated using the measurements of average times of the chemicals ozone (O 3), sulfur dioxide (SO 2), nitrogen dioxide (NO 2), carbon monoxide (CO), particles smaller than 2.5 micrometers (PM 2.5), and particles smaller than 10 micrometers (PM 10).
