In a burn patient, when should you administer oxygen according to protocol?

• A. O2 if SpO2 <94% or respiratory distress or CO toxicity
• B. O2 only if respiratory distress
• C. O2 as a blanket for all burn patients
• D. O2 never used in burns

Answer: (A)

Ensuring adequate oxygenation is essential in burn patients because inhalation injury and possible carbon monoxide exposure can seriously compromise oxygen delivery. The target is to keep SpO2 above about 94%, and to intervene when you see signs that oxygenation is at risk. Give oxygen when the patient’s SpO2 is below 94% or there are signs of respiratory distress (such as increased work of breathing, use of accessory muscles, or airway injury signs). Suspect carbon monoxide poisoning when exposure is possible (enclosed space fires, soot in the airway, or altered mental status). In that case, administer high-flow oxygen immediately, typically 100% O2 via a non-rebreather mask or bag-valve mask, to hasten CO off-loading from hemoglobin. This approach avoids assuming oxygen is needed for every burn patient regardless of status (which would be the “blanket” approach) and recognizes that oxygen is not used only for respiratory distress if there’s no indication of hypoxia or CO exposure. It also acknowledges that pulse oximetry can be misleading in CO poisoning, so treating suspected CO exposure with high-flow oxygen is important even if SpO2 appears normal.
