B30 Patient Monitor
10-6
Table 10-2 Other problems related to airway gas measurement
Table 10-3 Other problems related to arrhythmia measurement
Weak pulsation 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.
• Check the patient status.
• Check the NIBP cuff position and
attachments.
• Check that the cuff is not damaged.
x-Lead off
• Check the leadwires and their
connections.
x measurement(s) removed Measurement module has been
removed.
• Reconnect the module if you want
to restart the measurement.
x high/low
• Check the patient status.
• Adjust the alarm limits.
Zero error Zeroing during gas calibration failed.
• Repeat the calibration procedure.
<0.6 (displayed in the RQ
field)
Gas exchange measurement out of
physiological range.
• Check the patient status.
Symptom Possible cause and solution
Airway gas values
are too low
• Check the sampling line and connectors for leakage.
Symptom Possible cause and solution
Extra arrhythmia
alarms
The morphology of the ECG signal has changed.
• Start relearning manually through the ECG menu.
Extra Ventricular
Fibrillations are
detected
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.
