①
Whether or not the electrode placement is instable?
②
Whether or not the electrodes or lead cables are connected reliably?
③
Whether or not the electrodes and patient skin are cleaned and are smeared enough electric
gel?
④
Whether or not it is caused by patient's movement and breath?
⑤
Whether or not the electrodes or leads are in bad connection?
If you can not clear the interference after having taken all the measures above, use filter.
14.5 Troubleshooting List
Phenomenon
Cause of failure
Remedy
Too large
interference,
disorderly
waveform
1. Grounding cable is not
connected reliably.
2. Lead cables are not connected
reliably.
3. There is AC interference.
4. Patient is nervous and can not
keep quiet.
1. Check lead cables, grounding
cable and power.
2. Do patient treatment well.
Baseline burr
1. AC interference is large.
2. Patient nervous, and EMG
interference is large.
1. Amend the environment.
2. If the bed is made of steel,
replace it.
3. The power cable and lead
cables are not parallel or too
close to each other.
Not
regular
waveform,
large
up-and-down,
beeline figure
1. Bad electrode conductivity.
2. Battery capacity lack.
3.
Bad
connection
between
electrodes and patient skin.
4. Loose connection between lead
cables and the device's plug.
5.
Bad
connection
between
electrodes and lead cables.
1. Use alcohol of high quality.
2. Clean electrode slices and the
skin below them with alcohol.
3. Charge the battery.
Baseline draft
1. Low power.
2. Patient movement.
1. Charge the battery.
2. Keep patient still.
