What is considered a normal oxygen saturation level in adults?

Normal oxygen saturation levels in adults are typically observed in the range of 95% to 100%. This range indicates that the blood is adequately saturated with oxygen, which is essential for optimal cellular function and metabolic processes.

When oxygen saturation levels fall below 95%, it can be a sign of inadequate oxygenation in the body, which may necessitate medical evaluation or intervention. While levels slightly above 100% can occur in specific situations (such as with supplemental oxygen), for general assessments, the widely accepted normal range remains firmly at 95% to 100%.

This understanding is crucial in clinical practice, as it helps healthcare providers gauge respiratory efficiency and make informed decisions regarding patient care and the need for respiratory support.
