What is considered a normal pulse oximetry reading?

A normal pulse oximetry reading typically falls within the range of 95% to 100%. This level indicates that the blood is adequately saturated with oxygen, which is crucial for ensuring that organs and tissues receive sufficient oxygen to function properly.

A reading of 95% or higher suggests that the body is effectively transporting oxygen, while a reading below 90% may signal potential respiratory or cardiovascular issues, necessitating further medical evaluation. Thus, any value noted as 95% or higher is generally accepted as indicating a healthy oxygen saturation level in a person.
