1. An adapter configured to provide an interconnection between at least one pulse oximetry sensor of a plurality of possible sensor types and at least one monitor of a plurality of possible monitor types, said sensor having a light source and a light detector, said monitor having a driver, a signal conditioner and an information element detector, said adapter comprising:

  • a plurality of signal paths configured for detachable connection to at least one of said monitor and said sensor, a first of said signal paths in communication with said driver and said light source when said adapter is in communication with said monitor and said sensor, a second of said signal paths in communication with said light detector and said signal conditioner when said adapter is in communication with said monitor and said sensor, and at least one of said signal paths being in communication with said information element detector when said adapter is in communication with said monitor; and

    at least one adapter element connected to at least one of said signal paths, said adapter element modifying a characteristic of said at least one signal path so that said sensor and said monitor are jointly operable to measure oxygen status, said at least one adapter element operable to convey information about said sensor types to said monitor, said information being compatible with said information element detector.
