What is the typical range for SpO2 in a healthy individual?

The typical range for SpO2, or peripheral capillary oxygen saturation, in a healthy individual is generally considered to be between 95% and 100%. This range indicates that the oxygen levels in the blood are sufficient to meet the body's needs. When SpO2 levels fall below 95%, it may suggest inadequate oxygenation, which can prompt further evaluation and possible intervention. Maintaining oxygen saturation within this optimal range is crucial for overall health and is an important parameter monitored in clinical settings.

Levels above 100% are unrealistic because oxygen saturation cannot exceed 100% under normal physiological conditions. Similarly, ranges that suggest lower saturation percentages indicate potential hypoxia and could reflect respiratory or circulatory issues that need addressing, making them less representative of healthy individuals. Thus, the choice of 95% to 100% accurately reflects the norms for SpO2 in individuals who are not experiencing any health problems.
