Technical Information

Principles of Operation

Pulse oximetry is a non-invasive method that passes red and infrared light through perfused
tissue and detects the fluctuating signals caused by arterial pulses. Well-oxygenated blood is
bright red, while poorly oxygenated blood is dark red. The pulse oximeter determines
functional oxygen saturation of arterial hemoglobin (SpO

2

) from this color difference by

measuring the ratio of absorbed red and infrared light as volume fluctuates with each pulse.
