Symptom
Airway gas values
are too low
Table 10-3
Symptom
Extra arrhythmia
alarms
Extra Ventricular
Fibrillations are
detected
10-6
Explanation
Weak or unstable oscillation signal
due to improper cuff position or
attachment, weak or abnormal blood
circulation, slow heart rate associated
with artifacts, moving or disturbed
patient during measurement, small air
leak.
Measurement module has been
removed.
Zeroing during gas calibration failed.
Gas exchange measurement out of
physiological range.
Other problems related to airway gas measurement
Possible cause and solution
•
Check the sampling line and connectors for leakage.
Other problems related to arrhythmia measurement
Possible cause and solution
The morphology of the ECG signal has changed.
•
Start relearning manually through the ECG menu.
Patient's medical condition.
•
Check the patient status.
Low amplitude signal in some ECG leads.
•
Leads I and II: Select the one with the largest amplitude to ECG1.
•
After selecting the leads, start relearning manually.
What to do
•
Check the patient status.
•
Check the NIBP cuff position and
attachments.
•
Check that the cuff is not damaged.
•
Check the leadwires and their
connections.
•
Reconnect the module if you want
to restart the measurement.
•
Check the patient status.
•
Adjust the alarm limits.
•
Repeat the calibration procedure.
•
Check the patient status.
