Final answer:
A normal range for arterial oxyhemoglobin saturation (SpO2) is 95-100 percent. Pulse oximeters are commonly used to measure SpO2 by sending two different wavelengths of light through a thin part of the body, such as the finger, and calculating the amount of light absorbed by oxygenated hemoglobin.
Step-by-step explanation:
A normal range for arterial oxyhemoglobin saturation (SpO2) is 95-100 percent. This is the percentage of hemoglobin sites occupied by oxygen in a person's blood. Pulse oximeters are commonly used to measure SpO2 by sending two different wavelengths of light through a thin part of the body, such as the finger, and calculating the amount of light absorbed by oxygenated hemoglobin.
