Troubleshooting
NOTE: Always check the patient’s condition first in problematic situations or if an alarm is triggered. See also “ Messages .” Also note that if the
measurement or function does not appear on the screen, check module connections.
Airway gases
Values are too low:
• Check the sampling line and connectors for leakage.
• Check the patient status.
Values are too high:
• Check the sampling line for blockage.
• Check the patient status.
Module does not work:
• Check and clean the filter if necessary.
• Check the water trap. If it was too full, liquid may have
entered the module. Replace the module and have it
checked by authorized service personnel.
No airway gas values:
• Check that the gas sampling line is connected to the water
trap.
Arrhythmia
Extra arrhythmias are detected.
• Start relearning manually through
ECG
- Relearn .
Extra Ventricular Fibrillations are detected:
• Check the patient.
• Check that the amplitude signals are sufficient:
Leads I and II: Select the one with the largest amplitude to
ECG 1.
After selecting the leads, start relearning manually.
Batteries
Battery operation time is markedly shortened:
• Condition the batteries, see “ Conditioning the batteries ” and
the “User's Reference Manual.”
ECG
ECG signal is noisy or no QRS is detected:
• Ensure that the patient is not shivering.
• Select the correct ECG filter through
ECG
- ECG Setup -
Filter .
• Check the electrode quality and positioning. Do not place
them on body hair, bones close to skin, layers of fat and
major muscles. Pre-gelled electrodes are recommended.
• Change the ECG lead.
• Remove the ECG cable from the module and reinsert it.
