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).
Why won't my Nonin 8500 turn on?
The device might not be turning on due to several reasons: the batteries could be depleted (replace all 6 batteries), the batteries might be installed incorrectly (verify battery orientation), or a metal contact in the battery compartment might be missing or damaged (contact Nonin Technical Service).
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.
What does a dash in the leftmost position of the SpO display on Nonin 8500 mean?
A dash appearing in the leftmost position of the SpO display indicates a sensor fault (disconnect, failure, misalignment, or incompatibility with the monitor). Verify that the sensor is correctly connected to the device and the patient; replace the sensor if the condition persists.
How to troubleshoot an inconsistent Pulse Rate when using Nonin Medical Equipment with an electrosurgical unit (ESU)?
If you experience an inconsistent pulse rate or an amber Pulse Quality display while using an electrosurgical unit (ESU) with the device, it may be that the ESU is interfering with the pulse oximeter performance. Assess the patient and move the device, cables, and sensors as far away from the ESU as possible.
What does it mean when dashes are displayed in both the SpO and Pulse Rate displays on Nonin 8500?
If dashes are displayed in both the SpO and Pulse Rate displays, it means that no signal is being detected because the sensor is not plugged in (verify the sensor connections) or there is a sensor failure (replace the sensor).
Why are numeric displays blinking at once per second on Nonin 8500 Medical Equipment?
If the numeric displays are blinking once per second, it means that the batteries are low (replace all 6 batteries) or the batteries are installed incorrectly (verify battery orientation).
Why is the Pulse Quality LED not blinking green on my Nonin Medical Equipment?
If the Pulse Quality LED is not blinking green, it could be due to an inadequate pulse signal or the sensor is not correctly positioned (reposition the sensor), the sensor is restricting blood circulation at the sensor site (remove the restriction or relocate the sensor), excessive ambient light (reduce ambient light), excessive patient motion (reduce patient motion), the patient is wearing nail polish or artificial nails (remove nail polish or artificial nails), or performance degradation from an arterial catheter, blood pressure cuff, or infusion line (reduce or eliminate the source).
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 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.
