What to do if segments of SpO2 are missing on Nonin Medical Equipment?
If segments of the SpO2 or display are missing, it indicates defective LED displays. The displayed values may not be reliable, so discontinue use of the device.
What to do if the displayed pulse rate on Nonin Medical Equipment doesn't correlate with the ECG monitor?
If the displayed pulse rate does not correlate to the pulse rate displayed on the ECG monitor, it could be due to excessive motion at the sensor site (eliminate or reduce the cause of the motion or reposition the sensor), the patient may have an arrhythmia (assess the patient), a non-compatible sensor is being used (replace the sensor with a Nonin- branded PureLight sensor), or the ECG monitor may not be functioning properly (assess the patient).
What does it mean if the Pulse Quality LED is blinking amber with each pulse on my Nonin Medical Equipment?
If the Pulse Quality LED is blinking amber with each pulse, it indicates that the quality of the pulse signal at the sensor site is inadequate. Assess the patient and try repositioning the sensor or selecting an alternate sensor site.
What to do if the Pulse Quality display is blinking red and the SpO and/or Pulse Rate displays are dashes on Nonin Medical Equipment?
If the Pulse Quality display is blinking red and the SpO and/or Pulse Rate displays are dashes, it means there is an inadequate signal at the sensor site (assess the patient and reposition the sensor or select an alternate sensor site), inadequate pulse signal due to excessive motion (reduce patient motion and reposition or relocate the sensor), or sensor failure (replace the sensor).
What to do if Nonin Medical Equipment printer is not printing after changing Prn mode?
If the printer is not printing after changing the Prn mode, reset the pulse oximeter by turning it off and then on.
How to fix Nonin Medical Equipment 8500 that will not power up?
If your Nonin 8500 device isn't powering up, the issue might be due to: * Depleted batteries: Replace all six batteries. * Incorrect battery installation: Verify the battery sequence. * Faulty battery door: Replace the battery door if the metal contact is missing.
What does it mean if the Pulse Quality LED is blinking amber with each pulse on Nonin Medical Equipment?
If the Pulse Quality LED is blinking amber with each pulse, this indicates that the quality of the pulse signal at the sensor site is inadequate. Assess the patient. Reposition the sensor or select an alternate sensor site.
How to deal with Degradation of device performance of Nonin 8500 Medical Equipment?
Degradation of device performance can be caused by electromagnetic interference (EMI). Remove the device from the EMI environment.
What to do if numeric displays are blinking at once per second on Nonin 8500?
If the numeric displays are blinking once per second, this may indicate low batteries (replace all 6 batteries) or incorrect battery installation (verify battery orientation).
What to do if numeric display segments are missing on Nonin 8500?
If numeric display segments are missing, it indicates defective LEDs. Discontinue use of the device.
