SpO2 stands for?

SpO2 stands for?

• A. Saturation of Peripheral Oxygen
• B. Systemic Oxygen
• C. Standard Oxygen
• D. Special Oxygen

Answer: (D)

SpO2 refers to peripheral oxygen saturation. It’s the percentage of hemoglobin molecules carrying oxygen in the blood at peripheral sites, usually measured with a pulse oximeter on the finger or earlobe. The term highlights two ideas: oxygen saturation and the peripheral (not central) measurement site. Clinically, this value estimates how well oxygen is being transported in the arterial blood to body tissues. Normal SpO2 is typically about 95–100%. The measurement isn’t about systemic, standard, or special oxygen; it specifically indicates how much oxygen is bound to hemoglobin in the peripheral circulation.
