Troubleshooting
Problem: Erroneous NBP measurement
Solution:
1. Check for proper cuff size:
Too small a cuff can give an erroneously high value.
Too large a cuff can give an erroneously low value.
NOTE
For proper fit of an NBP cuff, the arm should be measured from the top of
the shoulder joint to the elbow. Divide the length by 2 and measure from the
middle of measurement on the arm. Measure the circumference in
centimeters around the arm. Refer to the NBP cuffs for proper fitting size.
2. Check for residual air left in the cuff from a previous measurement. This could
indicate a hardware problem that may require service.
3. Make sure the cuff is not too tight or too loose.
4. Make sure the cuff and the heart are at the same level; otherwise hydrostatic
pressure will offset the NBP value.
5. Watch for pulsus paradoxis.
6. Check for leak in cuff or tubing.
CHANGE BATTERY Message displayed with SPO2 data displayed—The batteries in the Apex oximeter
are low. There is approximately 1 hour of reserve power left in the batteries.
Change the batteries.
Message displayed, no SPO2 data displayed—The batteries in the Apex oximeter
are depleted. Replace the batteries. This is a system Warning alarm. The alarm
will sound, and a red alarm button will appear on the CIC Pro center display. If the
batteries are not replaced within 20 minutes, all SPO2 parameter information will
be removed from the display. If the batteries are replaced within 20 minutes, SpO2
monitoring will resume.
SPO2 PROBE The probe has been disconnected from the oximeter (no data is displayed).
SIGNAL SpO2 data continues to be displayed, but the quality of the signal is questionable.
Check the patient and the probe.
NO DATA The oximeter is still connected, but no valid data is being transmitted to the
receiver. Check that the patient is within antenna range. If the problem persists,
contact GE Service.
SPO2 PROBE OFF The probe is off the patient. Check the probe.
The saturation value is X The oximeter is still connected, but no valid data is being received at the receiver.
The patient may be in an area of poor antenna reception, where some, but not all
data is being transmitted.
This message remains on the CIC Pro center for three minutes. If no data is
detected after three minutes, the message changes to NO DATA.
