Which SpO2 range is listed as normal in the material?

• A. 88-92%
• B. 93-97%
• C. 95-99%
• D. 97-100%

Answer: (B)

SpO2 is the percentage of hemoglobin carrying oxygen, measured noninvasively with a pulse oximeter. The material lists 93-97% as the normal range. This range reflects typical arterial oxygenation in healthy adults and accommodates small variations in readings from the device and natural physiological fluctuations. Values in this window indicate adequate oxygen delivery without signaling the need for intervention. Readings significantly lower than this, such as in the 80s or low 90s, suggest hypoxemia and warrant evaluation and possible oxygen therapy. Readings higher than this range, especially if not on supplemental oxygen, may be due to measurement artifact or recent oxygen administration, but the material defines 93-97% as the normal reference.
