1. A method for driving a medical sensor for use on a subject, comprising:

  • generating a light drive signal with a variable current below a first maximum current limit, the light drive signal being configured to produce an emitted light in a medical sensor;

    receiving a sensor signal from the medical sensor, in response to the emitted light;

    determining a parameter based on the received sensor signal;

    changing the maximum current limit based on the parameter; and

    generating the light drive signal in accordance with the changed maximum current limit.
