Overview
An Alarm warns of a patient condition, such as a vital-sign reading that is outside of
acceptable limits. When an alarm occurs, the red light on the monitor flashes and the
numerics of the violating alarm limits on the display turn red. If tones are not suspended,
the alarm tone sounds.
An Alert warns of an equipment condition, such as a low battery or a detached lead.
When an alert occurs, the yellow light on the monitor flashes and a message describing
the error condition appears on the display. If tones are not suspended, the alert tone
sounds.
Alarms have priority over alerts. If an alarm and an alert are detected simultaneously, the
monitor notifies you of the alarm. It then notifies you of the alert only if the alert condition
still exists after the alarm condition is removed.

to silence the audible tone for 90 seconds at the monitor and at Acuity.
•
Silencing the audible tone does not remove visual alarm or alert indications.
•
Silencing the audible tone causes an alarm or alert suspend at Acuity.
•
When the alarm or alert condition is corrected, all alarm or alert indicators cease
and all alarms are immediately rearmed.
4. After caring for the patient, verify that alarm limits are enabled and correctly set.
WARNING If you turn off or modify any alarm limits while responding to an
alarm, restore the appropriate alarm limits before you resume monitoring.
Suspending the Alarm Tone
If this feature is enabled in the monitor configuration (See “Monitor Configuration” on
page 111), you can suspend all alarm tones for all parameters—preventing the alarm tone
from sounding if an alarm condition occurs—while monitoring a patient. If an alarm
condition occurs while the alarm tones ars suspended, the monitor presents visual alarm
indicators but does not sound the tone.
In the monitor configuration, the alarm tone suspension period can be set to Disabled, to
Always On, or to a period: 90 sec or 2, 3, 4, 5, 10, 15, 30, or 60 minutes.
Note
The factory default suspension period is 4 minutes.
•
If it is configured to Disabled, you cannot suspend the alarm tone at the monitor.
•
If it is configured to Always On and you set Suspend Audible Alarms to On,
then the alarm tone remains suspended until:
Note
•
you set Suspend Audible Alarms to Off or
•
monitor power is turned off and then turned on again or
•
the monitor is reconfigured
Suspend Audible Alarms does not affect the behavior of the alarm silence/
reset feature ( ). Pressing
always either silences a sounding alarm tone for 90
seconds or resets the audible alarm if it was already silenced.
To Suspend the Alarm Tone
1.
Access the Setup menu. (See “To Access the Setup Menus” on page 38.)
2. Highlight Suspend Audible Alarms (Figure 86).
The configured suspension period—90 seconds in this example—is displayed to the
right of the line.

Customizing Alarm Limits
At the Monitor
Typically, each institution defines the patient alarm limits for adult, pediatric, and neonatal
patients, and then configures the monitor with those alarm limits before putting the
monitor into service.
Alarm limits can be temporarily customized for an individual patient while the monitor is in
use. Later, when the monitor is turned off in preparation for monitoring another patient,
the temporary alarm limits are lost and the configured alarm limits are restored.
To Temporarily Customize Alarm Limits for the Current Patient
1.
Highlight the vital sign for which you want to set custom limits.
2. Press
3. Highlight the limit you want to change.
4. Set a new alarm limit.

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 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 “Improving
NIBP Accuracy with Smartcuf” on page 71.)

Message
Possible Cause and Suggested Response
NIBP Fault.
No valid blood pressure found.
The patient mode setting is incorrect or the wrong hose or
cuff is being used for the current patient mode.
NIBP Fault.
Calibrating.
Please wait.
The monitor periodically calibrates (zeroes) the NIBP
channel to make sure it can properly make NIBP
measurements. No NIBP monitoring can be done until the
calibration is completed. Other normal monitor operation
continues during NIBP calibration.
NIBP Fault.
Calibrating.
Minimize motion.
Motion is detected during a periodic NIBP calibration.
Minimize patient motion or motion on the cuff, or
disconnect the cuff. Motion-generated noise on the
pressure transducer can cause the calibration to continue
indefinitely.
NIBP Fault.
Low battery.
NIBP disabled.
The battery is too far discharged to operate the NIBP
channel. Insert the monitor into a powered cradle.
NIBP Fault.
Service required.
NIBP disabled.
Have the monitor serviced.
NIBP Fault.
Kinked or neonate hose.
A hose is kinked or a neonate hose is detected in the adult
patient mode. Check the hose and the patient mode
selection.
NIBP Fault.
Artifact present.
Minimize motion.
The monitor has detected too much artifact to allow
accurate readings. Take steps to reduce artifact. Position
the patient’s limb away from the body so the applied cuff is
not in contact with the patient’s body or any other object
such as a bed rail.
Comms Fault.
Check Acuity/network connection.
The monitor detects a network communication problem.
Comms Fault.
Check USB connection.
The monitor detects a problem in communication with the
cradle. Detach and reattach the USB cable.
