Embodiments of the present invention include systems and methods that relate to pulse oximetry. Specifically, one embodiment includes an oximeter sensor comprising a light emitting element configured to emit light, a light detector configured to detect the light, and a memory chip having a built-in trimmed resistor, the trimmed resistor having a resistance value that is detectable by a monitor.

Method and circuit for storing and providing historical physiological data

A sensor has codes useful for a monitor which can be authenticated as accurate. The sensor produces a signal corresponding to a measured physiological characteristic and provides codes which can be assured of being accurate and authentic when used by a monitor. A memory associated with the sensor stores both data relating to the sensor and a digital signature. The digital signature authenticates the quality of the code by ensuring it was generated by an entity having predetermined quality controls, and ensure the code is accurate.

Sensor with signature of data relating to sensor

Embodiments of the present invention include systems and methods that relate to a sensor with memory. Specifically, one embodiment includes a method of sensor operation, comprising emitting light from a light emitting element of the sensor, detecting the light with a light detecting element of the sensor, storing sensor model identification data within a memory of the sensor, and providing access to the memory to facilitate reading the sensor model identification data with an oximeter monitor.

Oximeter sensor with digital memory encoding sensor data

Embodiments of the present invention include systems and methods that relate to a sensor with memory. Specifically, one embodiment includes a method of sensor operation, comprising emitting light from a light emitting element of the sensor, detecting the light with a light detecting element of the sensor, and providing a manufacturer identification of the sensor stored within a memory of the sensor to an oximeter monitor.

A memory in a sensor is used to store multiple coefficients for a physiological parameter. In one embodiment, not only are the sensor's specific calibration coefficients stored in a memory in the sensor for the formula to determine oxygen saturation, but multiple sets of coefficients are stored. The multiple sets apply to different ranges of saturation values to provide a better fit to occur by breaking the R to SpO2 relationship up into different pieces, each described by a different function. The different functions can also be according to different formulas for determining oxygen saturation.

Pulse oximeter sensor with piece-wise function

The present invention provides a memory chip for use in an oximeter sensor, or an associated adapter or connector circuit. The memory chip allows the storing of patient related data, such as patient trending data or a patient ID, to provide enhanced capabilities for the oximeter sensor. In addition to providing unique data to store in such a memory, the present invention include unique uses of the data stored in such a memory.
