Which statement best describes oxygen therapy in these BLS protocols?

• A. O2 saturation PRN
• B. Oxygen should be avoided
• C. Always give oxygen to all
• D. No oxygen before transport

Answer: (A)

Oxygen therapy in BLS is guided by the patient’s oxygen saturation as measured by a pulse oximeter, along with clinical signs. The best statement reflects giving supplemental oxygen as needed to keep SpO2 in a safe range, rather than giving it to everyone automatically or withholding it. Why this works: Oxygen is a medication. By monitoring saturation, you treat hypoxia promptly and avoid unnecessary oxygen exposure in patients who already have adequate oxygen levels. In practice you start or adjust oxygen to maintain target saturation, including providing oxygen before transport if the readings indicate hypoxia or the patient is in distress, and you titrate as needed. The other options imply either universal administration, complete avoidance, or withholding until after transport, which doesn’t align with using oxygen saturation to guide therapy.
