Index 2MF Overview
The Index 2MF "Finger"
The Simulator system has a patented optical “finger” that takes the place of an actual
patient's index finger. This finger works with any pulse oximeter that detects SpO2
(Saturation of Peripheral Oxygen) through the index finger (as opposed to the earlobe or
toe) tissue.
Inserting the Index finger into the pulse oximeter probe effectively connects the two
devices for testing purposes.
Note
When connecting a finger sensor, onto the Simulator's “finger,” make sure
that the red LEDs (light emitting diodes) are on the bottom and that the
pulse oximeter fingertip sensor is on as far as possible.
Simulator Electrical Testing (MFE Version only)
Electrical testing of oximeters is similar to optical testing. However, all electrical testing
simulations are output through the electrical port on the back of the Simulator, thus
eliminating the probe from the circuit. FBC makes specific cables to connect the
electrical port on the Simulator to oximeter port for electrical testing. Check FBC website
or price list for details about these specific cables. A separate probe check is performed
via the probe port on the back of the unit that analyzes LEDs, photodiodes, and wire
resistance for potential problems.
Simulation Settings
Once connected, the Simulator can simulate virtually any patient condition, with
programmable SpO2 ranges from 35% to 100%, pulse rates from 30 BPM to 250 BPM,
and an amplitude factor (non-pulsatile components such as soft tissue and venous blood,
also called the DC component) of 0% to 20%.
Running Tests
The Simulator runs through a series of simulations to test the sensitivity and performance
limits of the pulse oximeter in question. You can run one test or a series of tests, with
