How a Pulse Oximeter Works
A finger pulse oximeter functions by shining red and infrared light through your finger. As these beams pass through your digit, the oximeter’s photodetector measures how much red and infrared light is transmitted through it.
How to Use an Oximeter
Slide your finger into the device’s opening and your oximeter will automatically turn on, complete a brief self-test and begin to measure your oxygen level and pulse rate.
