Which statement correctly describes when supplemental oxygen is used in EMR practice and how it is delivered?

• A. For cardiac arrest only; delivered via bag-valve mask.
• B. For hypoxic or in respiratory distress; delivered via nasal cannula or non-rebreather mask per protocol and monitor.
• C. For all patients regardless of condition; delivered via nasal cannula or non-rebreather mask per protocol.
• D. Only after advanced life support; delivered via mask and tracheal route.

Answer: (B)

Supplemental oxygen is used to improve oxygenation when a patient is hypoxic or in respiratory distress. In EMR practice, start with the least invasive option that provides the needed oxygen level: a nasal cannula for mild hypoxia, or a non-rebreather mask when a higher concentration is needed, all chosen per protocol and with ongoing monitoring of SpO2 and the patient’s work of breathing. Oxygen isn’t reserved only for cardiac arrest, nor is it delivered only after advanced life support, and routine oxygen delivery is not typically via bag-valve mask unless actively ventilating. The approach described—oxygen for hypoxia or distress delivered by nasal cannula or non-rebreather mask per protocol with monitoring—is the best fit.
