1. A noninvasive oximetry sensor, comprising:

  • a light source configured to emit light;

    a detector configured to output a signal indicative of light attenuated by a digit of a patient; and

    a finger gauge configured to determine proper sizing for said sensor, the gauge including;

    a tab including an opening sized to determine whether a cross-section of said patient'"'"'s digit is appropriate for said noninvasive sensor, wherein when a periphery of said cross-section is larger than an inner edge of said opening, said tab indicates that said digit is too large for said noninvasive sensor, said sensor configured to output a signal indicative of light attenuated by said digit, andan association portion mechanically associating the tab with the sensor.
