What term represents the clinical measurement of oxygen percentage in the blood?

• A. Blood Pressure
• B. Oxygen Booster
• C. Oxygen Saturation
• D. Hemoglobin Level

Answer: (C)

Oxygen saturation is the term that refers specifically to the clinical measurement of the percentage of oxygen bound to hemoglobin in the blood. This measurement is crucial because it indicates how well oxygen is being transported throughout the body, which is vital for cellular metabolism and overall health.

In clinical settings, oxygen saturation is typically assessed using a pulse oximeter, a non-invasive device that can quickly provide accurate readings. Normal oxygen saturation levels generally range from 95% to 100%, and monitoring these levels is essential for diagnosing and managing respiratory and cardiovascular conditions.

Other terms listed do not represent the measurement of oxygen in the blood. For example, blood pressure refers to the force of circulating blood against the walls of blood vessels, which is vital for assessing cardiovascular health but does not provide information about oxygen levels. An oxygen booster may refer to supplemental oxygen devices but does not measure oxygen levels directly. Hemoglobin level pertains to the concentration of hemoglobin in the blood, which is important for understanding overall oxygen-carrying capacity but does not reflect the percentage of oxygen saturation.
