Quick takeaways
- Diagnosis of carbon monoxide poisoning can be challenging due to its nonspecific symptoms, but testing involving noninvasive co-oximetry and detecting oxygen saturation gap and hyperlactatemia can provide clues.
- Treatment for carbon monoxide poisoning focuses on reducing end-organ oxygen utilization, maintaining adequate cardiac output, and increasing ventilation and oxygenation, with mild cases treated using 100% inhaled oxygen and severe cases often requiring intubation, sedation, and ventilation to decrease metabolic demand.
Deep dives
Sources and Symptoms of Carbon Monoxide Poisoning
Carbon monoxide poisoning can occur from burning hydrocarbon fuels with insufficient oxygen, such as furnaces, stoves, generators, and gas-powered appliances. Other sources include suicide attempts using automobile exhaust, burn victims, and exposure to paint remover. Symptoms can vary and include headache, dizziness, delirium, nausea, vomiting, and cardiopulmonary symptoms like chest pain and arrhythmia.
