HOW THE PULSE OXIMETER WORKS
The Pulse Oximeter works by shining two
light beams into the small vessels or
capillaries of the finger to determine the
user's the blood oxygen saturation
percentage and pulse rate that is then
displayed on the Pulse Oximeter's screen.
The unit uses the phrase "SpO2" to
identify the oxygen saturation level and
displays it as a percentage of full capacity
(100%). Pulse rate is identified by the
phrase "PR bpm" and is displayed as
beats per minute.
