SpO2 stands for Saturation of peripheral oxygen.
In more detail, SpO2 refers to the percentage of oxygen bound to hemoglobin in your red blood cells, measured in your peripheral blood vessels (typically a finger). This provides an estimate of how much oxygen your blood is carrying. A healthy SpO2 level is usually between 95% and 100%. It is a vital sign frequently monitored by healthcare professionals, particularly in situations involving respiratory or cardiovascular compromise. Lower than normal readings can indicate hypoxemia and may warrant further investigation and treatment.
