During toxic inhalation management, which monitor is recommended if available?

• A. Carboxyhemoglobin monitor PRN, if available
• B. Blood glucose monitor
• C. Pulse oximeter
• D. ECG monitor

Answer: (A)

Directly measuring how much carbon monoxide is bound to hemoglobin provides the most accurate assessment of CO exposure and its impact on oxygen delivery. If available, a carboxyhemoglobin monitor guides management by quantifying COHb levels and helping determine the need for intensified oxygen therapy or consideration of advanced therapies. A pulse oximeter can be misleading in CO poisoning, as it cannot distinguish carboxyhemoglobin from oxyhemoglobin and may show a falsely normal saturation. Other monitors like glucose or ECG do not inform about CO exposure or the resulting tissue hypoxia in inhalation injuries.
