Rationale:
- Asymptomatic persons and those without suspected exposure to elevated levels of CO have a low incidence of CO toxicity.
|
|
Evidence:
- A case series of patients presenting to an emergency department for 1 month with headache and nausea showed a 24% incidence
of occult CO poisoning in an inner city during winter (12); other larger case series of patients presenting to emergency departments with similar symptoms had a much lower detection
rate between 0.3% (13) and 2.8% (14) of occult poisoning that did not influence treatment.
- A prospective observational study showed that routine use of CO screening in all prehospital emergency responses found elevated
environmental CO levels only 3.4% of the time, and in no incident was the elevated CO thought to be related to the chief complaint
(15).
