Message
Possible cause and suggested response
ECG
ECG Fault.
XX lead failed.
Lead XX (LA, LL, RA, C, or RL) has very poor contact or no
contact with the patient. Check for proper connection and
replace the electrode if needed.
ECG Fault.
XX, XX leads failed.
Leads XX and XX (any two leads on a 5-lead cable) have very
poor contact or no contact with the patient. Check for proper
connection; replace electrodes if needed.
ECG Fault.
Multiple lead fail.
At least three leads of a 5-lead cable or at least two leads
of a 3-lead cable have very poor contact or no contact with
the patient. Check for proper connection; replace electrodes
if needed.
ECG Fault.
Excessive offset.
At least one channel has excessive offset. At least one
electrode is old, contaminated, or defective. Replace the
electrodes.
ECG Fault.
Cable disconnected.
The ECG cable is unplugged.
NIBP
NIBP Fault.
Air leak.
Check hose.
The monitor could not properly inflate the cuff. Check the
hose and cuff for leaks.
NIBP Fault.
Kinked hose.
Check hose.
The monitor could not properly inflate the cuff. Check for a
hose kink between the monitor and the patient.
NIBP Fault.
Overpressure condition.
The pressure in the cuff exceeded the acceptable limits for
the current patient mode. Check the hose and retry the
measurement.
NIBP Fault.
Weak Pulses.
Can’t find Sys/Dia.
Not enough pulses to determine the systolic or diastolic
pressures, but a mean pressure is available. Squeeze all air
from the cuff and reapply it.
NIBP Fault.
Artifact.
Can’t find Sys/Dia.
The systolic or diastolic pressures are unreliable due to
artifact, but a mean pressure is available. Usually caused by
patient motion.
NIBP Fault.
No pulses detected.
The cuff might not be properly applied to the patient, or the
patient might not have detectable pulses due to shock or
arrhythmias.
WARNING The monitor cannot determine whether
this alert has a physiologic cause or a cuff
application cause. Always evaluate the patient for
presence of life

threatening conditions when this
message occurs.
NIBP Fault.
Connect ECG to reduce NIBP artifact.
NIBP artifact prevents a valid reading. Connect ECG
electrodes to improve NIBP measurements. (See
