Hi, I'm doing preliminary research for the design of an electrical SpO2 simulator.

As this kind of simulators simulate a sensor with a live finger (and not the finger itself) I would need to add Ratio to SpO2 % calibration curves for each commercial brand.

Is there a source for this curves? I'm willing to pay for them as long as they're the real ones

So far I've only been able to find the one for BCI.

This curves depend on the R and IR wavelength so they vary from brand to brand and sometimes between sensors of the same brand.

Thanks in advance.:D
 

Thank you for the idea.:D

I understand I can reconstruct the R curves using hemoglobin absorption spectra and the wavelength pair used by each sensor.

What worries me is scattering, I´m unsure if the effect is already accounted for in the absorption spectra or it might introduce a difference between the actual R curves and the ones I will estimate.
