What is the normal SPO2 rate at sea level?

The normal oxygen saturation level, measured as SpO2, at sea level typically falls within the range of 95% to 100%. A saturation of 98% or higher is often considered optimal in healthy individuals, as it indicates that the body is effectively transporting oxygen to the tissues. This level of saturation is critical for maintaining proper physiological function, especially in environments that may be challenging, such as during physical exertion or in the presence of health issues.

While 96% is also a commonly cited minimal threshold for acceptable oxygen saturation, 98% is a strong benchmark for optimal health. Maintaining an SpO2 level at or above 98% suggests excellent oxygenation status, which is essential in tactical combat scenarios where physical performance and cognitive function are paramount. Lower levels might prompt concern and necessitate immediate assessment and intervention, making the choice of 98% or higher the most accurate and appropriate answer.
