Final answer:

A pulse oximeter measures oxygen levels in the blood using light absorption to determine oxygen saturation, aiding healthcare providers in administering the correct amount of oxygen to patients.


Explanation:

A pulse oximeter is a device used to measure the amount of oxygen in a person's blood, typically by clipping onto a thin part of the body, like the fingertip. It works by sending different wavelengths of light through the finger and measuring the light that is absorbed by the hemoglobin to determine oxygen saturation levels. This information helps healthcare providers determine the appropriate amount of oxygen to administer to a patient in need.
