Question

As measured by a pulse oximeter, normal oxygen saturation in the blood is ______% to __________%.

a. 50, 50
b. 70, 75
c. 85, 90
d. 95, 100

Answer 1

Normal oxygen saturation in the blood, as measured by a pulse oximeter, is 95% to 100%.

Step-by-step explanation:

Normal oxygen saturation in the blood, as measured by a pulse oximeter, is 95% to 100%. A pulse oximeter is a device that measures the amount of oxygen in the blood by sending two different wavelengths of light through the finger and measuring the amount of light absorbed by the oxygenated hemoglobin. Readings below this range indicate low blood oxygen levels, also known as hypoxemia.
