What is the recommended action for pulse oximetry reading between 90-94%?

• A. Discharge immediately
• B. Repeat in one hour, up to three times
• C. Conduct an echocardiogram immediately
• D. Start supplemental oxygen

Answer: (B)

A pulse oximetry reading between 90-94% indicates that there is a potentially low but not critically low oxygen saturation level. In this range, it’s important to monitor the patient's condition closely rather than taking immediate, aggressive actions. Repeating the measurement in one hour, up to three times, allows for a reliable assessment of whether the low reading is a transient issue or indicative of a more serious underlying condition. This approach helps in making an informed decision based on trends over time rather than reacting to a single measurement.

Immediate discharge, conducting an echocardiogram, or starting supplemental oxygen may not be warranted without a clearer understanding of the patient’s condition. Monitoring provides an opportunity to observe any changes in oxygen saturation levels before determining if further intervention is necessary. If the readings remain low or worsen, then another step may be justified based on follow-up findings.
