1. A pulse oximeter comprising:

  • a noninvasive sensor that when positioned proximate a measurement site on a monitored patient is configured to output signals responsive to light attenuated by body tissue at the measurement site of the monitored patient;

    a signal processor and a display processor, the signal processor configured to process the output signals to determine measurement values responsive to an oxygen saturation of arterial blood of the monitored patient, the display processor configured to receive the measurement values; and

    a display responsive to the display processor to present display indicia to a caregiver, the display indicia being responsive to said determined measurement values and the display indicia comprising a gauge panel, the gauge panel comprising;

    a gauge face formed as an arc including lowered end portions and a raised center portion between said lowered end portions, said raised center portion including an approximate top center, said gauge face including an active face portion and an inactive face portion, said active face portion including a plurality of positions along said arc, each position mapped to a percentage or range of percentages of said determined measurement values of said oxygen saturation so that the active face portion sweeps through a range of the measurement values, said plurality of positions including positions corresponding to a low range of said determined measurement values, positions corresponding to a cautionary range of said determined measurement values, and positions corresponding to a normal range of said determined measurement values, wherein a top center position of said plurality of positions is located at said approximate top center of said raised center portion of said arc and said top center position corresponds to at least one optimum value of said determined measurement values and corresponds to one end of said active face portion of said arc, said inactive face portion corresponding to an unused portion of the arc of said gauge face;

    a digital readout set to a numeric value of a current value of said determined measurement values, said digital readout substantially centered underneath said arc, at least a portion of said digital readout also between said lowered end portions, said active face portion of said arc generally positioned above an approximate side half of the digital readout;

    a parameter indicator set to a type of physiological parameter, said type of physiological parameter including oxygen saturation; and

    some or all of a radially extending indicator positioned to extend from beneath said top center position radially toward said arc, said radially extending indicator terminating proximate said arc with a designator portion identifying where said current value of said determined measurement values falls along said plurality of positions along said arc.
