According to recommended guidelines for titrating supplemental oxygen during PAP titration, which statement is correct?

• A. Target SpO2 should be between 88-94%
• B. Supplemental oxygen should be initiated at 2L/min then titrated upward
• C. Supplemental oxygen should be connected directly to the PAP mask
• D. Supplemental oxygen can be added when SpO2 is less than 88% for greater than 15 minutes

Answer: (A)

Titrating supplemental oxygen during PAP titration aims to keep the patient’s oxygenation within a safe, stable range while PAP therapy treats airway collapse. The recommended target SpO2 is 88–94% because it provides enough oxygen to prevent desaturation without pushing saturations too high, which can be unnecessary and, in susceptible patients (like those with COPD), may blunt the respiratory drive and risk CO2 retention. Oxygen should be delivered through the PAP circuit via the device’s oxygen port so the flow mixes properly with the inspiratory air and remains consistent despite mask leaks and PAP pressures. Starting at a fixed higher flow and simply increasing it later is not ideal; begin with the lowest effective flow and titrate up only as needed to keep SpO2 in the 88–94% range. Desaturation should be addressed as it occurs rather than waiting a fixed duration, and adjustments should be guided by continuous SpO2 monitoring to maintain the target range throughout the titration.
