What is a normal range for pulse oximetry values?

The normal range for pulse oximetry values is considered to be 95% to 100%. This range indicates that the hemoglobin in the blood is adequately saturated with oxygen, which is essential for proper cellular function and overall health. Values falling within this range suggest that the body is effectively transporting oxygen to tissues and organs.

When considering other ranges, values below 95% may indicate varying degrees of hypoxemia, where the oxygen saturation is insufficient for optimal metabolic activity. A level of 100% would mean complete saturation, which is typically not harmful but can indicate certain physiological conditions. Values above 100% are generally not possible in a healthy individual and would suggest either a measurement error or an erroneous environmental condition. Therefore, 95%-100% is the clinically recognized threshold for healthy oxygen saturation levels in individuals.
