Final answer:
The average range for SpO2/SaO2 levels, which indicate oxygen saturation in hemoglobin, is between 95-100%, as measured by a pulse oximeter.
Step-by-step explanation:
The average range for SpO2/SaO2 levels, which represent the percentage of hemoglobin sites occupied by oxygen in a patient's blood, is typically between 95-100%. A device called a pulse oximeter is used to monitor these levels by sending two wavelengths of light through a body part like a fingertip and measuring the absorption by hemoglobin with a photodetector. This percent saturation is an important indicator of a person's respiratory status, with lower percentages indicating conditions such as hypoxemia or hypoxia, indicating low blood oxygen levels.
Percent saturation is measured using a pulse oximeter, which works by sending two different wavelengths of light through the finger to measure the amount of oxygen in the blood. Normal readings on a pulse oximeter range from 95-100 percent. Lower percentages indicate low blood oxygen levels, or hypoxemia.
