Chapter 1 – Getting Started
Introduction
The Arctic Sun Temperature Management System is a device that monitors
and controls patient temperature within a range of 32°C to 38.5°C (89.6°F to
101.3°F). The system consists of the Model 5000 and disposable ArcticGel
™ Pads. The Arctic Sun system delivers temperature-controlled water
ranging between 4°C and 42°C (39.2°F and 107.6°F) through the pads
adhered to the patient’s skin. This results in highly efficient conductive
heat transfer between the water and the patient.
The Arctic Sun Model 5000 was designed with ease of service in mind
and incorporates several features that will assist clinical engineers in
maintaining its performance. These features include: negative pressure
flow that eliminates water leaks, real-time air leak detection, and
performance monitoring. It also includes access to alarm logs and past
system case data, real-time diagnostic information, simplified calibration
and maintenance, and modular construction allowing for simple repair if
required.

Chapter 3 Theory of Operation
Main Hydraulic Circuits
Circulation Circuit - circulates temperature-controlled water from
the Circulation Tank through the ArcticGel Pads and returns to the
inlet port of the Circulation Pump. The speed of the Circulation Pump
varies to maintain -7.0 PSI (0.5 bar) at the Pressure Sensor. Since
water in the ArcticGel Pads flows under negative pressure, a break
in the circuit, such as a pad being punctured or disconnected, will
result in air leaking into the system instead of water leaking out. Air
in the system is removed in the Circulation Tank and exits through the
tank vent. When warmer water is required, the heaters located in the
CirculationTankareenergized.Theheaterpowerisdependentuponthe
flow rate through the circulation tank and the difference between the
water temperature and the commanded water temperature. The heater
hasfourelementsthatarecycledonsequentiallytominimizepower
fluctuations in the mains supply.
Chiller Circuit – maintains the water in the Chiller Tank at approximately
4⁰C. Water is gravity-fed into the centrifugal Chiller Pump and is then
pumped through the chiller’s evaporator and returned to the Chiller
Tank. The refrigerant system’s cooling capacity is controlled by a
refrigerant valve. When the Chiller Circuit approaches 4⁰C, the cycling of
the valve can be heard.
Mixing Circuit – when cold water is required to cool the Circulation
Circuit, the Mixing Pump pulls water from the Circulation Tank and
meters it into the Chiller Tank. Cold water overflows from the Chiller
Tank into the Circulation Tank. The speed of the mixing pump is
dependent upon the flow rate through the circulation tank and the
difference between the water temperature and the commanded water
temperature.

Ancillary Hydraulic Circuits
Filling - When filling, the Fill Valve is opened and water is drawn up
through the valve by the Circulation Pump. Water returns through
the Circulation Tank to the Supply Tank. Negative Pressure must be
generatedattheinletoftheInlet/OutletManifoldforllingtooccur,
therefore the Fluid Delivery Line must be attached. ArcticGel Pads
should not be attached to the Fluid Delivery Line during filling.
Preconditioning – The system can be programmed to precondition
water prior to initiating therapy. In this mode, the Bypass Valve opens
and allows temperature-controlled water to circulate internally to
bring the Circulation Tank and Supply Tank water to a pre-programmed
temperature.
Empty Pads – To empty water from the ArcticGel Pads, the Vent Valve
is opened, which enables air to enter the pads. Water is pulled from
the pads by the Circulation Pump and returned through the Circulation
Tank to the Supply Tank.
Electronic Control System
The electronic system consists of two independent subsystems: control
and monitor. The control subsystem is responsible for delivering therapy
to the patient. The monitor subsystem confirms the safe operation of the
control subsystem. Each subsystem has an independent microprocessor,
audio alarm, and both water and patient temperature sensing circuits.
The control subsystem performs the following functions:

Chapter 5 – Alarms and Alerts
The Arctic Sun safety system continually monitors the state of the device
and the patient, and issues alarms or alerts to notify the user of conditions
that may interfere with patient safety or system performance.
There are two types of conditions: Alarms and Alerts.
An Alarm notifies the user of a condition that may potentially pose an
unsafe situation with respect to the patient or the device; an Alarm
interrupts the procedure.
An Alert informs the user about patient and device status without
interrupting the procedure.
A list of Alarms and Alerts that the user might encounter appears at the
end of this chapter.
Alarms
An Alarm is denoted by an audio signal that repeats every 10 seconds until
the Alarm is cleared.
The Alarm screen will appear displaying 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.
Fig. 5-1 Alarm screen
Main Safety Alarms
While there are multiple alarms and safety features in the Arctic Sun, 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)

109 Esophageal Probe Recommended Control Strategy 3 has been chosen which allows the Patient Target tempera-
ture to be set between 32.0 °C and 32.9 °C (89.6 °F to 91.2 °F).
For patient target temperatures between 32ºC to 32.9ºC (89.6ºF to 91.2ºF) an
esophageal temperature probe should be used. During the hypothermia
induction phase, the esophageal temperature tracks real-time core tempera-
ture changes more closely than bladder or rectal temperature. Due to this lag
time when using bladder or rectal temperature sites, actual patient core tem-
peratures may be lower than measured. Therefore, the use of esophageal
temperature is recommended for patient temperature control below 33ºC.
110 Data File Corrupted The data file which contains the system default settings has been corrupted.
The system has automatically reset the system to the factory defaults.
111 Confirm New Patient A New Patient treatment was selected, but this system has treated a patient
within the last 6 hours and a Current Patient treatment is still available.
112 Confirm Return to Cooling Phase Treatment is currently programmed to be in the Rewarming phase, but the
Start button in the Cool Patient window was pressed.
113 Reduced Water Temperature Control The system has detected that the water temperature has not been controlled
as accurately as expected in the last 30 minutes.
This situation may be temporary due to sudden patient temperature changes,
interruption in water flow, or blockage of air flow by an obstruction or dirty
filter.
