When is supplemental oxygen typically provided in rehab?

• A. Supplemental oxygen is provided to all personnel at all times during rehab.
• B. Supplemental oxygen is provided only during field operations.
• C. Supplemental oxygen is provided only after transport is arranged.
• D. Supplemental oxygen is provided when indicated by medical assessment for hypoxia, chest pain, or other respiratory distress, with monitoring.

Answer: (D)

Supplemental oxygen is reserved for when a medical assessment indicates the person needs it due to insufficient oxygen in the blood or respiratory distress. In firefighter rehab, clinicians watch vital signs and oxygen saturation continuously. If signs of hypoxia appear—low oxygen saturation, chest pain, increased work of breathing, or shortness of breath—the team administers supplemental oxygen and adjusts the flow to bring saturation to a safe level while monitoring the patient’s response. This targeted approach prevents unnecessary oxygen use and ensures treatment is based on the person’s current condition. It isn’t given to everyone all the time, and it isn’t limited to field operations or only after transport; it’s used when indicated and with ongoing monitoring.
