- Carbon dioxide content
Carbon dioxide content: A measure of the bicarbonate level in the blood. The normal carbon dioxide content may vary somewhat from one laboratory to another. For example, it may be 20 to 29 milliequivalents per liter (mEq/L) of blood, 22 to 34 mEq/L, etc. Higher than normal carbon dioxide levels may reflect excessive loss of […]

- Carbon monoxide poisoning
Carbon monoxide poisoning: A potentially deadly condition caused by breathing carbon monoxide gas, which prevents oxygenation of the blood. Common causes of carbon monoxide poisoning include malfunctioning furnaces and the use of kerosene heaters or similar devices in unventilated indoor spaces. Carbon monoxide is also emitted by automobile and other engines, so these should not […]
- Carboxyhemoglobin
Carboxyhemoglobin: Hemoglobin that has carbon monoxide instead of the normal oxygen bound to it. Carbon monoxide has a much stronger binding to hemoglobin than oxygen. Carboxyhemoglobin is formed in carbon monoxide poisoning and leads to oxygen deficiency in the body. The source of the carbon monoxide may be exhaust (such as from a car, truck, […]
- Carboxyhemoglobinemia
Carboxyhemoglobinemia: The presence of carboxyhemoglobin in the blood. Carboxyhemoglobin, hemoglobin that has carbon monoxide bound to it, is formed in carbon monoxide poisoning, as from exhaust (such as from a car, truck, boat or generator), smoke from a fire, or tobacco smoke.
