If SpO2 remains low despite oxygen therapy as per facility protocol, what is the recommended action?

• A. Discontinue therapy
• B. Escalate according to facility protocol for oxygen therapy
• C. Stop therapy temporarily and reassess
• D. Switch to a different sensor

Answer: (B)

When SpO2 remains low despite starting oxygen, the action that best fits safe care is to escalate according to the facility’s oxygen therapy protocol. This approach provides a clear, standardized plan for increasing oxygen support promptly and safely, aiming to bring the patient’s oxygen saturation back into the target range.

First, verify there isn’t a simple issue with the setup: ensure the oxygen delivery device is functioning and correctly connected, and check that the sensor is placed properly and reading accurately. If readings still stay low after confirming setup, follow the protocol’s steps to escalate—this could mean increasing FiO2 or flow, advancing to a higher level of oxygen delivery, or using a more intensive device as permitted, with continuous monitoring and reassessment. The goal is to Correct hypoxemia quickly while maintaining safety.

Discontinuing oxygen or pausing therapy would leave the patient at risk for worsening hypoxia, and simply switching sensors without addressing the actual oxygenation status doesn’t treat the underlying problem.
