6.4 Troubleshooting Alarms and Alerts
The Arctic Sun is designed with the patient's and operator's safety in mind. The Control Module has
redundant, cross-checking systems and a multitude of self-tests. It detects inappropriate conditions
and notifies the user. Many of these conditions can be addressed by clinical actions alone. These
are described in the Operator's Manual. If the alarm or alert cannot be resolved clinically or is
recurrent, the matter should be addressed by technical personnel. Table 6.4 below is intended as an
aid in such an investigation.
Alerts and Alarms have specific definitions:
Alert: Alerts are intended to inform the user about patient and equipment status without interrupting
the procedure.
Alarm: When an Alarm condition occurs, there is a chance that a potentially unsafe condition has
occurred, or could occur with respect to the equipment, the patient, or an improperly functioning
component.
Alarms are divided into two types – recoverable and non-recoverable. Recoverable alarms may be
cleared when a condition is met. Non-recoverable alarms require correcting the condition and
powering the system back up to clear the alarm. Non-recoverable alarms are identified as such on
the display.
Refer to the Alarm & Alert Troubleshooting Table for a description of alarm and alert codes and
messages and the condition limits that triggered the alarm or alert.
Note: This guide includes non-recoverable alarms. These alarms should be address only by
someone trained and qualified to work on this system.
