The present application is a continuation of U.S. application Ser.

The monitor 202 also comprises a HbCO bar 212 where in an embodiment a plurality of LED's activate from a bottom toward a top such that the bar “fills” to a level proportional to the measured value. For example, the bar 212 is lowest when the dangers from carbon monoxide poisoning are the least, and highest when the dangers are the greatest. The bar 212 includes indicia 214 that provide an indication of the severity of carbon monoxide saturation in a patient's blood. As shown in FIG. 2, the bar 212 and the indicia 214 continuously indicate the concentration of HbCO in about 5% increments. The indicia 214 indicate a measurement of HbCO saturation percentage between about 0 and about 50% with a granularity of about 5%. However, an artisan will also recognize from the disclosure herein a wide variety of ranges and granularities could be used, the indicia 214 could be electronically displayed in order to straightforwardly increase or decrease resolution, or the like. For example, HbCO may advantageously be displayed with greater resolution than ±about %5 in a lower portion of the scale. For example, an HbCO bar may advantageously include a scale of about <3%, about 6%, about 9%, about 12%, about 15%, about 20%, about 25%, about 30%, about 35%, and about >40%.
The monitor 202 also comprises a perfusion quality index (PI™) bar 240 (which quantifies the measure of perfusion of the patient) where in an embodiment a plurality of LED's activate from a bottom toward a top such that the bar “fills” to a level proportional to the measured value. In one embodiment, the PI™ bar 240 shows a static value of perfusion for a given time period, such as, for example, one or more pulses. In another embodiment, or functional setting, the PI™ bar 240 may advantageously pulse with a pulse rate, may hold the last reading and optionally fade until the next reading, may indicate historical readings through colors or fades, or the like. Additionally, the PI™ bar 240 may advantageously change colors, flash, increasingly flash, or the like to indicate worsening measured values of perfusion.
