1. A method, comprising:
- receiving a sensor into a sensor port;
reading code stored on a memory of the sensor; and
updating code stored in a memory of a monitor with the code stored on the memory of the sensor, wherein the code stored on the memory of the sensor comprises an updated algorithm and the updated algorithm comprises code configured to facilitate calculation of patient parameter values based on input from the sensor, and wherein the updated code remains stored in the memory of the monitor after the sensor is disconnected from the monitor, and wherein the updated code is available for use with at least one sensor that is subsequently used with the monitor.
