CO (Carbon Monoxide) - is the name of a very small molecule made up of 1 atom of carbon and 1 atom of oxygen.
CO Alarm - An instrument (sensor) that models the uptake of CO gas into the human body and alarms when uptake (blood CO concentration) exceeds predetermined levels set by standards organizations (eg. UL, CPSC).
CO Detector - An instrument (sensor) that measures CO in the air and provides nearly instantaneous output (usually digital) on that level.
CO Monitor - An instrument (sensor) that models the uptake of CO gas into the human body and provides information on body CO concentration at any level above normal. Needed by people who are especially at risk from CO exposure.
COHb (Carboxyhemoglobin) - Form of hemoglobin in the blood that has CO attached to it, preventing it from carrying oxygen to the body's cells.
Concentration - A measure of the amount of a subtance contained per unit of volume or weight of another substance.
Dose-Response - Refers to the amount of something that enters your body (breathe, drink, etc.) and the reaction of your body to it.
Flue - Pipe that the waste gases travel through from a furnace, water heater, etc. to the outside of a living/work space.
ppm (Parts per Million) - The number of units of something found in 1,000,000 units of air, or water, or whatever. Example: 20 ppm = 20 marbles mixed in with 999,980 pennies.
Symptom - Evidence or indication that something is present or has happened. Example: limp when you have a sore foot.
