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.
What to do if there is an inconsistent Pulse Rate or an amber Pulse Quality display during the use with electrosurgical unit (ESU) on Nonin 8500?
If you observe an inconsistent pulse rate or an amber Pulse Quality display during use with an electrosurgical unit (ESU), it's possible 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 to do if dashes are displayed in both the SpO and Pulse Rate displays of Nonin 8500 Medical Equipment?
If dashes are displayed in both the SpO and Pulse Rate displays, it could be due to no signal being detected because the sensor is not plugged in (verify the sensor connections) or sensor failure (replace the sensor).
What does it mean if a dash appears in the leftmost position of the SpO display on Nonin Medical Equipment?
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.
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 Pulse Quality LED does not blink green on Nonin 8500?
If the Pulse Quality LED isn't blinking green, try the following: reposition the sensor if it's not correctly positioned or if there is an inadequate pulse signal. Ensure that the sensor isn't restricting blood circulation at the sensor site, or relocate the sensor. Reduce ambient light and patient motion. Also, remove any nail polish or artificial nails. Reduce or eliminate performance degradation from an arterial catheter, blood pressure cuff, or infusion line.
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 Nonin 8500 device won’t turn on?
The device may not be turning on due to several reasons: the batteries may be depleted (replace all 6 batteries); the batteries might be installed incorrectly (verify the battery orientation); or a metal contact in the battery compartment could be missing or damaged.
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.
