If oxygen saturation is below the threshold, what is the recommended initial airway management step?

• A. Check ABG before giving oxygen
• B. Do not give oxygen
• C. Increase flow to 15 L/min immediately
• D. Start oxygen at 4 L/min and titrate

Answer: (D)

When oxygen saturation is below the target, the priority is to correct hypoxemia with supplemental oxygen in a controlled, titrated way. Start oxygen at a modest flow, such as 4 L/min, and adjust up or down to reach the desired SpO2. This approach provides enough oxygen to tissues without overdoing it, and it aligns with the idea of aiming for an approved saturation range while monitoring the patient.

Don’t wait for arterial blood gas results before giving oxygen, and don’t withhold oxygen when hypoxemia is present. Jumping to a very high flow (like 15 L/min) immediately isn’t necessary and can cause discomfort or unnecessary oxygen exposure; starting modestly and titrating keeps treatment efficient and safe.
