What is the normal range for blood oxygen saturation as indicated by a pulse oximeter?

The normal range for blood oxygen saturation, as indicated by a pulse oximeter, is typically considered to be between 95% and 100%. This range reflects the percentage of hemoglobin in the blood that is saturated with oxygen. Values within this range imply that the body is effectively transporting and utilizing oxygen, which is vital for various physiological processes.

Saturation levels below this normal range can indicate potential issues with respiratory or cardiovascular function, signaling that the body may not be receiving enough oxygen. Thus, interest in monitoring and maintaining blood oxygen saturation within this range is crucial for patient health, particularly in clinical settings. Monitoring devices like pulse oximeters are standard in healthcare to provide quick and non-invasive assessments of oxygen levels in patients.
