The detector should be CO - carbon monoxide but CO2 - carbon dioxide which is actually what you breath out when exhaling. The human body breaths in oxygen and breaths out CO2.

CO is non-detectable by your nose and poisonous and can only be measured by CO detector.

CO2 is not poisonous and is also a product of combustion but still can be dangerous if the oxygen level in the air gets below 18-19% and CO2 levels are high. Normal oxygen level is 20.9%

CO is produced when you do not have efficient combustion and you need detectors to measure, why houses need to have CO detectors if they are using furnaces that use a combustable fuel like wood, oil, propane, natural gas, kerosene, diesel. Wood is probably the least efficient fuel. All furnaces exhaust to the atmosphere to get rid of the combustion product such as CO2 and CO.
