Monitor Problem Solving
This guide is provided to establish the possible causes and solutions to some monitoring
problems.
MESSAGE
REASON
SOLUTION
DIAGNOSTICS
IN PROGRESS
Self test is being performed.
Wait for completion of self-test. See
Section 3.1.
SELF TEST
COMPLETE
Diagnostics OK.
ESU INTERFERENCE
Poor electrode
site preparation.
Excessive cautery
(ESU) noise.
Excessive high frequency noise.
Check site; rearrange electrodes.
Change electrodes. Use ECG cable
with choke.
LEAD FAULT
Lead off of patient.
Check electrodes / leads.
INTERFERENCE
Poor electrode site preparation.
Improper lead selection.Excessive 50
or 60 Hz noise.Wrong 3-Lead cable
may be in use.*
Check site. Change Lead selection.
Use proper ECG cable.
ARTIFACT
A 50 or 60 Hz noise is detected on the
ECG waveform. The displayed heart
rate may not be correct.
Check site. Change Lead selection.
Use proper ECG cable.
PROBLEM
REASON
SOLUTION
No trace for a
desired parameter
-Improper attachment of transducer to
monitor.
-Faulty transducer.
-Check transducer connection.-
Try a different transducer.
Wandering ECG
-Respiration artifact.
-Try a different base line lead
configuration.
Noisy ECG traces
-Loose or dry electrodes.
-Defective electrode wires.
-Patient cable or leads are routed too close
to other electrical devices.
-Apply new electrodes.-Replace
wires as necessary.
-Eliminate 60Hz interference.
-Use ECG cable with built-in
filter block.
Low Amplitude
ECG
-Electrode could be positioned over a bone
or muscle mass.
-Reposition electrodes.
-Press ECG SIZE key.
Excessive Electro-
surgical
Interference
-Inadequate skin prep prior to application
of electrode.
-Repeat skin prep and electrode
placement procedures.-Add
additional gel to electrodes.
AC Noise
-Gain set too high (set through SIZE key).
-Electrodes dry.
-Patient cable entwined with cables of other
electrical devices.
-Readjust as necessary.
-Re-prep skin and apply fresh,
moist electrodes.
-Separate patient cable from all
other cables.
Intermittent Signal
-Connections not tight and properly
secured.-Electrodes dry.
-Cable or lead wires damaged.
-Ensure proper connection.
(Electrode to lead, lead to
cable, cable to monitor.)
-Re-prep skin and apply fresh
moist electrodes.
-Check with continuity tester.
