Pulse oximeter probe & components: A pulse oximeter probe consists of a light emitter and a photodetector, encased in either a plastic probe (non-disposable) or an adhesive-type probe (disposable) – see Figure 1 for an example.  Typical pulse oximeter probes will read saturations between 70-100% to an accuracy of  plus or minus 2-4%, depending on manufacturer.  When saturations drop below 70%, the actual percentage displayed is no longer considered accurate.  NOTE:  Critical care areas have special probes designed for patients with cyanosis or poor perfusion (see Appendix B for details).

This procedure provides the necessary instructions for using the Siemens DCA Vantage analyzer .If required further detailed instructions and explanations of the DCA Vantage can be obtained from the DCA Vantage Operator’s Guide. This analyzer quantitates the percent concentration of hemoglobin A1C levels in whole blood one sample at a time. The assay is based on a latex immunoagglutination inhibition methodology. The DCA VANTAGE is able to measure HbA1c from 2.5% to 14.0 %.
