Chapter 6 - Alarms
The Arctic Sun™ Temperature Management System
safety system continually monitors the state of the device
and the patient, and issues alarms to notify the user of
conditions that may interfere with patient safety or system
performance.
Main Safety Alarms
While there are multiple alarms and safety features in the
Arctic Sun™ Temperature Management System, there are
five main safety alarms that will place the device into Stop
mode until the condition is addressed.
Alarm
Specification
High Patient Temperature 39.5°C (103.1°F)
Low Patient Temperature 31.0°C (87.8°F)
High Water Temperature
42.5°C / 44°C (108.5°F / 111.2°F)
Low Water Temperature
3.0°C / 3.5°C (37.4°F / 38.3°F)
System Self-Test Failure
At device Power On
Medium Priority Alarms
A Medium Priority Alarm is denoted by an audio signal
that repeats every 10 to 15 seconds until the Alarm is
cleared. The yellow Alarm screen will appear that displays
the alarm number, alarm title, a description of the problem
or conditions that triggered the alarm, and solutions and
instructions for troubleshooting and resolving the alarm
condition. If certain Alarm conditions are not acknowledged
by the operator within 2 minutes, a Reminder tone will
sound. All Alarm settings are maintained in the event of a
power interruption.
A
Medium Priority Alarm
notifies the
user a condition that may potentially
pose discomfort or reversible injury to
the patient requires operator response.
Failure to respond may result in
irreversible injury or death.
Note:
The system and any ongoing
therapy will be placed in Stop mode.
Each time the Arctic Sun™ Temperature Management
System is Powered On, a system self-test for the
independent safety alarm is automatically run. This test
simulates a “water high temperature” fault situation on both
the primary and secondary water temperature sensors. Both
the primary and secondary safety systems must respond to
the fault and be verified by the opposing safety system. If
either safety systems do not respond appropriately either an
alarm 80 or 81 will be issued. Contact BD Customer Support.
If power is unexpectedly lost, the device will beep to notify
the user. Upon restoration of power, the device will issue
alarm 45.
There are two types of conditions:
Medium Priority
Alarms
and
Low Priority Alarms
.
Non-Recoverable Alarms
If an Alarm condition occurs that prevents proper use of
the device or proper patient treatment (such as the five
main safety alarms discussed above), the system is placed
into Stop mode and will not allow therapy to continue. This
type of Alarm is known as Non-Recoverable. If this situation
occurs, cycle the device power (turn device Off then On). If
the alarm recurs contact Customer Support.
Recoverable Alarms
Other Alarms that temporarily Stop the device until the user
is able to correct the cause and clear the Alarm are classified
as Recoverable. If the condition that initiated the alarm is
not addressed and problem persists, the Alarm will recur.
If a Recoverable Alarm occurs:
• When an alarm is issued the device is placed into Stop
mode.
• Read the displayed instructions.
• Note the Alarm number.
• Press the Close button to clear the alarm.
• Follow the instructions to correct the alarm condition.
Perform the actions in the order listed until the alarm
condition is resolved.
• Once you have cleared the alarm, press the Start button
in the therapy window to restart therapy. You will hear a
tone and a voice stating “Therapy Started”.
If the condition does not resolve, contact Customer Support.
A
Low Priority Alarm
notifies the user
a condition that may potentially pose
discomfort or reversible injury to the
patient requires operator response.
Low Priority Alarms
A Low Priority Alarm is denoted by an audio signal that
repeats every 25 to 30 seconds. The blue Alarm screen
will appear that displays the alarm number, alarm title, a
description of the problem that triggered the alarm, and
solutions and instructions for troubleshooting and resolving
the alarm condition.
If a Low Priority Alarm occurs:
• Read the displayed instructions.
• Note the Alarm number.
• Press the Close button to clear the alarm.
• Follow the instructions to correct the alarm condition.
Perform the actions in the order listed until the alarm
condition is resolved. If the condition does not resolve,
contact BD Customer Support.
Notes
: If the condition that initiated the alarm is not
addressed and the problem persists, the Alarm will recur
and/or escalate.
To view alarms, the operator should stand in front of the
Arctic Sun™ Temperature Management System display
screen.
