How Do FingerSims Differ From Other Simulators?

The red light and infrared light that is used by the Pulse Oximeter passes through the FingerSims like they would a human finger. The FingerSims absorb light very much like a human finger based on the color dye in each Finger. They differentially absorb the light like the oxygenated and deoxygenated hemoglobin in a human Finger. They Test the Finger Probes the way they are designed to work, passing light through the Finger and measuring the results that pass through to the sensor.
