Abstract
The present invention is directed to an oximeter sensor that may be employed with a variety of oximeter processing and display units. The oximeter sensor includes a plurality of radiation emitting devices that are capable of providing a spectral content that is useful in the correlation of a number of different oximeter processing and display units. The oximeter sensor further includes a plurality of resistors, with each resistor being connected to a different oximeter processing and display unit to permit the particular oximeter processing and display unit to select an appropriate correlation curve.
