R-Curves (Red/IR Ratio)

R-Curves specify the relationship between the Red/IR ratio measured by pulse oximeters and the SpO2 value displayed . R-curves are obtained by each pulse oximeter manufacturer during clinical trials.

Preset Manufacturer's R-Curves (14): BCI, Criticare, CSI-Spot, Datascope, Datex, Hewlett-Packard (Philips), Masimo, Nellcor, Nellcor OxiMax, Nihon Kohden, Nonin, Novametrix, Ohmeda & Sensormedics
Please contact the factory for the availability of other R-Curves.
