A2 - Rahul G., Patwari Y1 - 2014 N1 - T2 - Clinical Emergency Medicine AB - Consider carbon monoxide (CO) poisoning in all patients with headaches, flu-like symptoms, altered mental status, or an unexplained anion gap metabolic acidosis.Immediately administer supplemental O2 to all patients with potential CO poisoning before any confirmatory studies.Pulse oximetry values will be falsely elevated in patients with CO poisoning as a result of the inability of standard oximetry to distinguish between oxyhemoglobin and carboxyhemoglobin.Symptomatology is often more important than the absolute carboxyhemoglobin level when determining treatment and disposition.
