During CPAP titration at 10 cm H2O, if SpO2 values stay 80-85% for 10 minutes with no respiratory events, what is the best action for the tech to take?

During CPAP titration at 10 cm H2O, if SpO2 values stay 80-85% for 10 minutes with no respiratory events, what is the best action for the tech to take?

• A. Follow protocol for supplemental oxygen
• B. Add a backup rate
• C. Increase CPAP to 15 cmH2O
• D. Contact on-call physician for ABG order

Answer: (A)

When SpO2 remains in the mid-80s for an extended period during CPAP titration without any respiratory events, the issue is inadequate oxygenation rather than airway collapse. The correct action is to follow the lab’s protocol and provide supplemental oxygen to bring oxygen saturation into the target range. This corrects hypoxemia without altering the CPAP pressure, which could complicate the titration if you start changing pressures when there isn’t an obstructive event driving the desaturation. Adding a backup rate isn’t indicated here because there are no respiratory events requiring ventilatory support. Increasing CPAP to a higher pressure isn’t warranted since there are no obstructive events to treat. Requesting an ABG order is not the immediate step; it’s typically reserved for cases where desaturation persists despite oxygen or where there are signs of hypoventilation or gas-exchange problems that trigger physician orders.
