Table 33. Common Problems and Resolutions
•
Check the OxiMax™ pulse oximetry sensor Directions for Use to confirm
appropriate usage and proper application. Check sensor and pulse oximetry
cable connections. Test the sensor on another patient and/or try another
OxiMax pulse oximetry sensor or pulse oximetry cable.
•
Perfusion may be too low for the oximeter to track the pulse. Check the
patient. Test the oximeter on someone else. Change the OxiMax pulse
oximetry sensor site. Try another type of OxiMax pulse oximetry sensor.
•
Interference may be preventing the oximeter from tracking the pulse. Keep
the patient still, if possible. Verify that the sensor is securely applied and
replace it if necessary. Change the sensor site. Electromagnetic interference
may be preventing the oximeter from tracking the pulse. Remove the source
of interference and/or try to stabilize the environment.
•
Use a type of OxiMax pulse oximetry sensor that tolerates more patient
movement; for example, an OxiMax adhesive sensor.
•
The OxiMax pulse oximetry sensor may be too tight, there may be excessive
ambient light, or the sensor may be on an extremity with a blood pressure
cuff, arterial catheter, or intravascular line. Reposition the sensor as necessary.
•
Check the status of your patient.
•
Perfusion may be too low for the oximeter to track the pulse. Test the oximeter
on another patient. Change the OxiMax pulse oximetry sensor site and/or try
another type of OxiMax pulse oximetry sensor.
•
Interference may be preventing the oximeter from tracking the pulse. Verify
the OxiMax pulse oximetry sensor is securely applied and replace it if
necessary. Change the sensor site. Use a type of OxiMax pulse oximetry sensor
that tolerates more patient movement; for example, an OxiMax adhesive
sensor. Electromagnetic interference may be preventing the oximeter from
tracking the pulse. Remove the source of interference and/or try to stabilize
the environment.
•
The OxiMax pulse oximetry sensor may be too tight, there may be excessive
ambient light, or the sensor may be on an extremity with a blood pressure
cuff, arterial catheter, or intravascular line. Reposition the sensor as necessary.
•
Press the ON/STANDBY key and allow the oximeter to shut off completely.
Then press the softkey again to turn back on the oximeter.
If the error code persists, record the number and provide this information to a
qualified service technician, or your local Nellcor representative.
•
Error Code "EEE 529 or 729" displays when the battery discharges to a critically
low level.
Ensure the SUPPLY VOLTAGE SELECTOR switch on the rear panel is set to the
proper voltage based on your location.
•
Press the ON/STANDBY key and allow the oximeter to shut off completely.
Allow the battery to charge for about ten minutes and then turn back on the
unit.
If the error code is still present, turn the unit off and allow it to continue to
charge. If the oximeter has been charged for 30 minutes and the error code
persists, contact Nellcor's Technical Services Department at 1.800.635.5267 or
your local Nellcor representative. See Error Codes for Non-correctable Failures,
