1. A disposable sensor cartridge for use with a noninvasive physiological sensor, the sensor cartridge capable of attaching to a tissue site and mating with a housing of the sensor, the sensor cartridge comprising:

  • a first portion comprising a first aperture configured to allow light emitted from one or more emitters of the sensor to travel through the first aperture such that the light is incident on a first region of a tissue site and travels through and is attenuated by body tissue of the tissue site, the attenuated light exiting the tissue site at a second region of the tissue site;

    a second portion comprising a second aperture configured to allow the attenuated light to travel through the second aperture and to be received by a detector of the sensor, the first and second portions coupled to define a cavity capable of receiving the tissue site; and

    an electrical component capable of electrical communication with the sensor,wherein the first portion is in contact with the first region while the cartridge is attached to the tissue site and the second portion is in contact with the second region while the cartridge is attached to the tissue site.
