Troubleshooting
This section discusses potential difficulties and suggestions
for resolving them. If the difficulty persists, contact a
qualified service person or your local Critikon
representative.
The service manual, which is for use by qualified service
personnel provides additional troubleshooting information.
PROBLEM: The pulse amplitude bar indicates a pulse, but
no oxygen saturation or pulse rate values appear on the
screen.
CAUSE:
• Excessive patient motion may be making it impossible
for the SpO
2
function to find a pulse pattern.
• The sensor may be damaged.
• The patient’s perfusion may be too low to allow the
SpO
2
function to measure saturation and pulse rate.
SOLUTION:
Check the patient.
• If possible, keep the patient still; check whether the
SpO
2
sensor is applied securely and properly, and
replace it if necessary; move the sensor to a new site;
or use a disposable adhesive sensor that may tolerate
more motion.
• Replace the sensor.
PROBLEM: The SpO
2
value or the pulse rate changes
rapidly; the pulse amplitude bar is erratic.
CAUSE:
• Excessive patient motion may be making it impossible
for the SpO
2
function to find a pulse pattern.
• An electrosurgical unit (ESU) may be interfering with
performance.
SOLUTION:
Check the patient.
• If possible, keep the patient still; check whether the
sensor is applied securely and properly, and replace it if
