・
Perform equipotential grounding with the peripheral devices using the equipotential
ground terminal as necessary.
・
If any noise source is near the patient, move it away from the patient as much as
possible.
Solution 2 : Attach the electrodes firmly.
・
Replace the lead cable if defective.
・
If any noise source is near the patient, move it away from the patient as much as
possible.
Solution 3 : If the patient is not wearing a pacemaker, set No for the pacemaker use in the
patient admit/discharge menu or ECG setup menu.
The “ECG not connected” message is displayed.
Cause : The ECG relay cable has been disconnected during ECG monitoring.
Faulty ECG relay cable type detection circuit can be considered.
Solution 1 : To cease monitoring, press the (Alarm Silence) key to silence the alarm.
Solution 2 : To continue monitoring, plug in the ECG relay cable. This will clear the message and
silence the alarm.
Respiration
The “CVA Detected” message is displayed.
Cause : Heartbeat is interfering and superimposed with the respiration waveform.
Solution : Place the electrode as shown below where the heartbeat will be less likely to interfere.

(For Europe) (For USA)
“0” is displayed for respiration rate, or apnea alarm is generated.
Cause : The respiration waveform amplitude is below the detection level (0.2
Ω
).
Solution 1 : Change the electrode site.
Solution 2 : Increase the waveform size.
The respiration waveform and respiration rate is not displayed.
Cause 1 : The ECG relay cable designed for electrosurgical knife is used.
Solution
: The impedance respiration cannot be measured if the cable designed for
electrosurgical knife is used. Use the cable other than electrosurgery-proof type ECG
relay cable if not using the electrosurgical knife.
Cause 2 : The impedance respiration measurement ceased.
Solution
: Turn ON the impedance respiration measurement on the ECG setup menu.
Note : If the pacemaker with the minute ventilation measuring function is used, turn OFF the
impedance respiration measurement. Otherwise, both the pacemaker and the monitor
will not be able to perform accurate measurement.
Cause 3 : Faulty respiration detection circuit can be considered.
The measured data is displayed as “
×××
”.
Cause : The respiration rate is outside the measurement range.
Solution :
・
Check the electrode application.
・
Replace the electrode, or check the lead cable connection.
