Breath carbon monoxide device. Breath carbon monoxide is the level of carbon monoxide in a person's exhalation. It can be measured in a breath carbon monoxide test, generally by using a carbon monoxide breath monitor (breath CO monitor), such as for motivation and education for smoking cessation and also as a clinical aid in assessing carbon monoxide poisoning.
Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. [3] Symptoms are often described as "flu-like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion. [1] Large exposures can result in loss of consciousness, arrhythmias, seizures, or death.
Leaks from the furnace, water heater, or other appliances can release invisible carbon monoxide into your home. Correctly installing an alarm can keep you safe. The Best Place to Put a Carbon ...
For sulfur dioxide (SO 2), the guidelines stipulate concentrations not exceeding 40 μg/m 3 24-hour mean. [2] For carbon monoxide concentrations not exceeding 4 mg/m 3 24-hour mean. [2] Up to 30 % of Europeans living in cities are exposed to air pollutant levels exceeding EU air quality standards.
The IDLH value has been set at 10% of the lower explosive limit although other irreversible health effects or impairment of escape due to toxicology exist only at higher levels. IDLH values for gases and vapors, used in industry
