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.

Silencing an Alarm or Alert Tone

A tone sounds whenever the monitor detects an alarm or alert condition.

To Silence the Currently Sounding Tone for 90 Seconds

1. P r e s s .

• The red light (alarm) or the yellow light (alert) flashes.

• After 90 seconds, if the condition is not corrected, the tone starts again.

• If the condition is corrected within 90 seconds of silencing the tone, the monitor

resets the tones for the next alarm or alert.

If a new alarm or alert condition occurs while an earlier alarm or alert is silenced, the

tone sounds again.

3. Press 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.

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.

• 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:

•you set Suspend Audible Alarms to Off or

• monitor power is turned off and then turned on again or

• the monitor is reconfigured

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.

WARNING If you turn off or modify any alarm limits while responding to an

alarm, restore the appropriate alarm limits before you resume monitoring.

Note The factory default suspension period is 4 minutes.

Note 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.

3. Highlight On (Figure 87).

Figure 87. Suspend Audible Alarms: On

• The alarm tone is suspended immediately.

If an alarm condition occurs during the suspension period, the alarm tone does

not sound.

• A count-down timer appears below the line to indicate the time remaining in the

suspension period.

• ‘Audio alarms suspended’ appears in yellow in the upper left corner of the screen.

• When the suspension period elapses, the alarm tone is again enabled.

Note If audible alarms are suspended, pressing cancels the suspension.

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.

Figure 88. Customizing Alarm Limits for the Current Patient

5. Press .

At Acuity

For a wireless monitor, patient alarm limits can also be customized from Acuity. (See the

user manual for any Acuity Central Monitoring Station.)

About ParamSet

Using ParamSet, you can quickly widen the alarm limits by a configured percentage

(relative to the patient’s alarming reading) for any vital sign.

For information about ParamSet, see “ParamSet” on page 154.

Responding to an Alarm

An alarm condition is indicated on the monitor in the following ways:

• The RED indicator (rightmost of three) above the display screen flashes.

• The numerics for the vital sign in alarm are displayed in RED.

• The alarm-tone sequence sounds repeatedly—3 short tones, a short pause, 2 short

tones, and a long pause.

Responding to an Alert

An alert condition (“Over view” on page 85) is indicated on the monitor in the following

ways:

• A flashing yellow light above the monitor display.

• A yellow alert message on the monitor display (for example, NO ECG CABLE

DETECTED).

• Repeated sounding of the alert-tone sequence (if tones are not suspended): 3 long

tones and a pause.

Alert Messages and Status Messages

Table 9. Alert Messages and Status Messages

Alert Type 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 “Improving

NIBP Accuracy with Smartcuf” on page 71.)

Directions for Use Alarms and Alerts 93

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.

Network

Communication

Comms Fault.

Check Acuity/network connection.

The monitor detects a network communication problem.

Comms Fault.

Check USB connection.
