59. Max sensor s calibration data model type troubleshooting codes and error detection data This unique oximetry architecture enables several new features with the N 600 When an OxiMax compatible sensor is connected to the N 600 the pulse oximeter will first read the information in the OxiMax sensor memory chip check it to make sure that there are no errors and then load the data to begin monitoring As the pulse oximeter reads the information it flashes the OxiMax sensor model number on its display This process takes a couple of seconds Once the reading process is complete the OxiMax sensor model number will stop flashing on the display and then the N 600 will begin monitoring The OxiMax sensor model number disappears after the pulse oximeter starts tracking the patient s SpO2 and pulse rate Pulse Oximeters containing OxiMax technology including the N 600 use calibration data contained in the OxiMax sensor in calculating the patient s SpO2 By having the calibration in the OxiMax sensor rather than the pulse oximeter the accuracy of many OxiMax sensors can be improved because the calibration coefficients can be tailored to each OxiMax sensor Consult the accuracy card included with the pulse oximeter for specific accuracy information for the N 600 with different Nellcor approved OxiMax sensors 129 Technical Discussion The N 600 uses the information in the OxiMax compatible sensor to tailor troubleshooting messages for the clin
