Carboxyhemoglobin Toxicity - StatPearls - NCBI Bookshelf
2023年4月17日 · The most crucial variables in determining total body carboxyhemoglobin levels are the ambient concentration of carbon monoxide in the air, duration of exposure, and alveolar ventilation. Since children have higher minute ventilation, they typically recover faster. On the other hand, the unborn fetus is highly susceptible to CO toxicity due to ...
Carbon Monoxide Poisoning - Carbon Monoxide Poisoning
Diagnosis is by carboxyhemoglobin levels and arterial blood gases (ABGs), including measured oxygen saturation. Treatment is with supplemental oxygen. Prevention is often possible with household CO detectors.
Carbon Monoxide Acute Exposure Guideline Levels
Three levels—AEGL-1, AEGL-2, and AEGL-3—are developed for each of five exposure periods (10 and 30 min and 1, 4, and 8 h) and are distinguished by varying degrees of severity of toxic effects.

These are the normal ranges for CO levels in the blood: Adults (nonsmokers): less than 2%, or 0.02 . Adult smokers: 4% to 5%, or 0.04 to 0.05 . Adult heavy smokers (more than 2 packs a day): 6% to 8%, or 0.06 to 0.08 . Newborn: 10% to 12%, or 0.10 to 0.12 . If your levels are higher, you may have CO intoxication or poisoning.
