The Centers for Disease Control and Prevention (CDC) is reminding healthcare professionals seeing patients from the areas affected by Hurricane Delta to maintain a high index of suspicion for carbon monoxide (CO) poisoning. Other people who may be exposed to the same CO source may need to be identified and evaluated.
The signs and symptoms of CO exposure are variable and nonspecific. A tension-type headache is the most common symptom of mild CO poisoning. Other common symptoms of CO poisoning are dizziness, weakness, drowsiness, upset stomach, vomiting, chest pain, and confusion.
Clinical manifestations of severe CO poisoning include cardiovascular and neurological effects: tachycardia, tachypnea, hypotension, metabolic acidosis, dysrhythmias, myocardial ischemia or infarction, noncardiogenic pulmonary edema, irritability, impaired memory, cognitive and sensory disturbances, ataxia, altered or loss of consciousness, seizures, coma, and death, although any organ system might be involved.
Although CO poisoning can be fatal, children, pregnant women, the unborn, persons with sickle cell disease, older adults, and persons with chronic illness (e.g., heart or lung disease) are particularly high risk.
