This device is designed to determine the percentage of arterial oxygen saturation of functional hemoglobin. Factors that may degrade pulse oximeter performance or affect the accuracy of the measurement include the following:

-excessive ambient light                                                        – inadequate signal

– excessive motion                                                                – venous pulsations

– electrosurgical interference                                                – anemia or low hemoglobin concentrations 

– blood flow restrictors (arterial catheters, blood pressure    – cardiogreen and other intravascular dyes

  cuffs, infusion lines, etc.)                                                   – carboxyhemoglobin

– moisture in the sensor                                                       – methemoglobin

– improperly applied sensor                                                 – dysfunctional hemoglobin

– incorrect sensor type                                                         – artificial nails or fingernail polish

Each time the system is turned on, all audible alarms are disabled for 2 minutes unless the operator presses the Audible Alarm Pause/Resume button.
