What is the normal range for SpO2 values?

80-85%
85-90%
90-100%
95-98%

The correct answer is: 90-100%

Normal SpO2 (oxygen saturation) values typically range from 90% to 100%. This range is considered optimal for healthy individuals and is essential for adequate oxygen delivery to tissues. In a well-functioning respiratory and circulatory system, oxygen saturation levels should remain within this range to ensure that the body has sufficient oxygen for metabolic processes. Values below this range can indicate hypoxemia, which may lead to tissue hypoxia and associated complications. It is crucial for healthcare professionals, particularly transport nurses, to monitor these levels closely to ensure patient safety during transport. Recognizing normal values is a fundamental aspect of patient assessment, enabling timely interventions if SpO2 levels drop below the expected range.
