Resp Troubleshooting
MESSAGE/ PROBLEM
REASON
SOLUTION
Resp. Waveform Too Large
1
Scales set
inappropriately.
1
Change lead selection.
2
Change Respiration
scale.
Resp. Waveform Too Small
1
Patient breathing is
shallow or patient is
turned on side.Scale set
inappropriately.
1
Change lead selection.
2
Change respiration scale.
False Apnea Alarm
1
Apnea delay may be
improperly set.
2
Patient may be having
frequent episodes of CVA.
3
Scale size may be too
low.
1
Choose another apnea
delay.
2
Reposition electrodes to
better detect respirations.
3
Change Respiration
scale.
No Resp. Waveform or Rate
Displayed
1
Respiration turned Off.
2
Patient connected using
ESIS choke cable.
3
Cable not connected.
1
Turn respiration On (Off
will be displayed in Resp.
window).
2
Check that proper patient
cable is used. Use non
ESIS patient cable.
3
Check cable.
“CHK Lead” Message
1
Increased impedance
caused by one of the
following:
2
Chest hair under
electrodes.
3
Dried electrode gel.
4
Electrode off. Lead off.
5
Cracked lead wires.
6
Poor skin prep.
1
Prep chest.
2
Change electrodes.
3
Replace electrode.
4
Replace lead.
5

Resp high impedance
1
Connections not tight
and/or properly secured.
2
Electrodes dry or loose.
3
Cable or lead wires
damaged.
1
Ensure proper
connection. (Electrode to
lead, lead to cable, cable
to monitor).
2
Re-prep skin and apply
fresh, moist electrodes.
3
Check with continuity
tester.
“CVA” Message
1
Can be caused by
shallow breathing or an
apnea event.
2
Patient HR and
respiratory rate identical.
1
Check the patient.
2
Adjust scales or leads if
necessary. Check the
patient.
Resp: Initialization Error
1
During the Resp module
power-on, as the Resp
module communication
stops, system fails to
communicate with
module.
