Problem
When I connect a monitor to the Acuity
System, a Communication Alert message
occurs.
The patient monitor displays a "Network
Fault" message after I press NET OFF and
disconnect from the Acuity System.
At the Acuity Central Station, a patient's
Virtual Monitor is in the yellow alert state
or red alarm state, and it shows a CHECK
WIRELESS or TELEMETRY DROPOUT
message.
While an alert is occurring at the Acuity
Central Station, one or more hallway
message panels are displaying a
different message.
When I change the Acuity System screen
view after it has not been changed for
several hours, a Monitor Communication
Lost alert occurs briefly for one or more
monitors, and then Unconfirmed Patient
ID status follows.
An NIBP equipment alert is suspended,
and then an NIBP measurement is taken.
The audible alert tone recurs after 90
seconds.
An equipment problem occurred during a
patient alarm, but I was not notified.
Welch Allyn Acuity Central Monitoring System
Explanation
Only monitors with Acuity System network connectors on their sides, with
Acuity System authorization and with software versions indicated in
Table 19 on page 175 can communicate with the Acuity System. For
compatibility with other monitors, contact your Welch Allyn representative.
Confirm the monitor's software version by reading the start-up screen when
the monitor is turned on. There is no visual indication that the monitor has
Acuity System authorization.
If this problem continues, contact qualified service personnel.
Acknowledge (or Disable) the alert.
If you wait a few seconds after selecting NET OFF, and then remove the
Acuity System cable from the patient monitor, you can prevent this alert.
1. If there is an audible tone, click Suspend to suspend the alarm tone.
2. Click whichever of these buttons is present:
• CONFIRM to dismiss the alert message for a number of hours
• RESET to dismiss the alert and put the monitor in the blue, "patient
intentionally disconnected" state
3. Bring the wireless monitor within range of a wireless access point.
4. If the problem persists, contact qualified service personnel.
Each message panel might be programmed differently, or a panel has lost
network communication, and it is displaying a message that was displayed
at the time of the loss.
Contact qualified service personnel.
After the monitors reconnect, click YES in the CONFIRM PATIENT? prompt to
confirm the patient's identification.
Go to the patient to investigate the cause of any NIBP equipment alert.
Acknowledge the alert, and then correct the problem.
WARNING During an alarm or alert suspension period, be aware
of new visual alarm indications that might occur on the patient
monitor or Virtual Monitor. During a suspension period, these
things occur at the Virtual Monitor and patient monitor:
•Audible tones are suspended for 90 seconds unless RESUME is
clicked at the central station or the alarm tone is reset at the
patient monitor.
•Alarms for lethal events—apnea, asystole, ventricular
tachycardia, and ventricular fibrillation—override the suspend
state.
•All other new alarms for the same patient are indicated only
visually, by additional red numeric highlights and arrhythmia or ST
status messages.
•New equipment alerts are indicated only after the first alarm and
alert conditions are corrected.
