What does SpO2 represent in medical terminology?

SpO2 refers to the measurement of oxygen saturation in the blood and indicates the percentage of hemoglobin that is saturated with oxygen. This value is crucial in assessing a patient's respiratory function and overall oxygen delivery throughout the body. A normal SpO2 level typically ranges from 95% to 100%, which signifies that the body's tissues are receiving adequate oxygen. In clinical settings, continuous monitoring of SpO2 can help identify potential hypoxemia or respiratory distress, enabling timely interventions.

Understanding SpO2 is particularly important for evaluating patients with respiratory issues, during anesthesia, or for those with chronic conditions such as COPD. Accurate knowledge about this measurement helps healthcare providers make informed decisions regarding treatment and management of patients.
