General Safety Precautions
WARNING! SYSTEMIC HYPOTHERMIA RISKS.
Systemic hypothermia may cause cardiac arrhythmia, patient shivering, or
other system or organ complications. Systemic hypothermia should only be
utilized under the supervision of a qualified physician.
When treating a patient with the System, appropriately qualified medical staff
must routinely and closely monitor the patient and must comply with the following
procedures:
Audible and visual alarms generated by the System require the
authorized individual to remain in close proximity to the patient
throughout the procedure.
Always verify the function of the System prior to insertion of an IVTM
catheter. In the event of a malfunction, have other means of cooling
available.
When combining the use of the System and other adjunctive means
of cooling, ensure that close observation of the patient is maintained.
Do not use the ZOLL System in conjunction with other temperature
maintenance devices that have an automatic temperature controller.
Temperature oscillations may occur that are dangerous to the
patient.
Performance of installation, operation, or maintenance procedures
other than those described in this manual may create hazards and
may cause the manufacturer’s warranty to become void.
Sterile components are designed for a single use only. If
unauthorized disposable components are used, proper operation
cannot be guaranteed and harm to the patient may result.
Proper aseptic technique must be used while making all sterile
connections to the System.
Never operate damaged or leaking equipment.
Never operate the equipment without coolant fluid in the coolant well.
Never use pure water, pure propylene glycol, or alcohol as a coolant
fluid.
Never operate the equipment while smoking or in the presence of
open flame.
Avoid touching the patient simultaneously with metal parts in the
Thermogard XP system.
WARNING! ELECTRIC SHOCK RISK DURING CARDIAC
DEFIBRILLATOR DISCHARGE.
The System’s protection against the effect of the discharge of a cardiac
defibrillator is partially in the Patient temperature probe. To prevent
potential hazards to the patient or operator, the system MUST be used in
conjunction with the approved patient temperature probes listed in
Specifications section of this manual.

This equipment has been tested and found to comply with the EMC limits of the
international standard IEC 60601-1-2. These limits are designed to provide
reasonable protection against interference in a typical medical installation. The
equipment can radiate radio frequency energy if not installed in accordance with
the instructions, and may cause harmful interference to other devices in the
vicinity. There is no guarantee that interference will not occur in a particular
installation. Always comply with the following:
To avoid the risk of electrical shock, do not remove any panels of the
product.
Refer servicing to qualified personnel.
Never operate equipment with damaged power line cords.
The Thermogard XP requires special precautions regarding EMC and needs to

Safety Information
Portable and mobile RF communications equipment can affect the Thermogard
XP.
CAUTION! DANGEROUS VOLTAGE.
Electric shock hazard. Always turn off the System and disconnect the
power line cord from the source before performing any service or
maintenance procedures, or before moving the System.
To avoid the risk of electric shock, this equipment must be connected to
a supply mains with protective earth.
WARNING!
The potential equalization conductor should be connected to the potential
equalization bus bar of the electrical installation when available. Refer to the
requirements in the IEC 60601-1 standard.
Primary Patient Temperature Probe (T1)
Failure
The System relies upon the patient temperature reading from an YSI-400 type
thermistor connected to the Primary Patient Temperature Probe (T1). There are
rare failures of this type of thermistor that cannot be detected by the System with
100% reliability. Failure of the T1 can result in either patient hypo- or hyperthermia. Death or serious injury to the patient may result. A secondary patient
temperature probe (T2) connection is therefore built into the system. For patient
safety, either use both the T1 and T2 connections or employ the T1 probe with
an independent frequent check of patient core temperature.
WARNING! NEVER CLINICALLY USE A RESISTOR IN
PLACE OF THE T1 TEMPERATURE PROBE
ZOLL supplies fixed value resistors and variable resistor test boxes (e.g the
TP-400 FOGG Box) for testing, training and demonstration purposes.
These can be plugged into the Primary Patient Temperature Probe T1
connection on the front of the System to represent a patient. Never use this
device, or other method, to circumvent the normal patient temperature
feedback control when the system is connected to the patient. Doing so
exposes the patient to the hazards associated with hypo- or hyper- thermia.
Death or serious injury may result.

Safety Information
Configuration Changes
WARNING!
No modification of this equipment is allowed.
CAUTION! CERTIFICATION REQUIREMENTS FOR
EXTERNAL EQUIPMENT CONNECTED TO THE SYSTEM
INTERFACES.
Equipment connected to the analog and digital interfaces must be certified
to the respective IEC standards (i.e., IEC 60950 for data processing
equipment and IEC 60601-1 for medical equipment). Furthermore, all
configurations shall comply with the system standard IEC 60601-1. Any
person who connects additional equipment to the signal input part or the
signal output part configures a medical system and is therefore responsible
that the system complies with the requirements of the system standard IEC
60601-1.
Priming the Saline Circuit
WARNING! DO NOT PRIME THE SALINE CIRCUIT WHILE
CONNECTED TO A PATIENT
During the priming operation, the air-trap alarm will be disabled. Air present
in the saline line may be circulated through the indwelling catheter.
Before priming the circuit or during troubleshooting for possible leak,
disconnect the heat exchange catheter, then connect the inflow and outflow
luer fittings of the saline circuit together.
Air Entry Into the Tubing Circuit
Air entry may occur with the failure of any part of the start-up kit, between the
saline bag and the outflow of the pump. In such cases, the integrity of the
catheter prevents air entry into the patient. In the rare event of a second,
simultaneous failure of the catheter, air entry into the patient is possible.
Air entry into the tubing circuit will usually, but not always, be associated with an
air trap alarm that will stop the System. Always investigate air trap alarms. The
cooling circuit is a closed loop–usually air trap alarms indicate a breach
somewhere in this closed loop (occasionally an air trap alarm can be caused by
condensation forming on the air trap exterior). With any air trap alarm, check both
the integrity of the catheter and the start-up kit (see below).
Periodically check the start-up kit for significant air bubbles and replace the kit if
necessary.

Safety Information
WARNING! NEVER CLINICALLY CIRCUMVENT THE AIR
TRAP ALARM
ZOLL supplies air trap “dummies” for testing, training and demonstration
purposes. These are fluid filled air trap assemblies that are separate from a
standard Start-up Kit assembly. Never use this device, or other method, to
circumvent the air trap alarm when the system is connected to the patient.
Doing so exposes the patient to the hazards associated with air embolism
should the catheter fail. Death or serious injury may result.
Check the Integrity of the Catheter
To check the integrity of the catheter, perform these steps in the indicated order:
1.
Stop the System.
2.
Using aseptic technique, disconnect the tubing from the catheter and
properly cap both the catheter and the tubing set.
3.
Fill a sterile 10 ml syringe with sterile saline.
4.
Connect the syringe to the INFLOW lumen of the catheter and
disconnect the outflow cap.
5.
Infuse the 10 ml of saline – it should flow out the outflow lumen.
6.
Cap the OUTFLOW lumen and pull and hold 5 ml of vacuum for at least
10 seconds. Approximately 4 ml of saline, but not blood, should enter the
syringe and you should be able to maintain the vacuum.
7.
Ease the vacuum, disconnect the syringe, and recap the INFLOW lumen.
Check the Integrity of the Start-up Kit Tubing
To check the integrity of the start-up kit tubing, perform these steps in the
indicated order:
1.
Stop the System.
2.
Look for obvious leakage.
3.
Remove the tubing from the pump and check it for damage. Replace it in
the pump if it is undamaged.
4.
Inspect the tubing from the pump to the patient for sources of fluid loss:
Look for damage to the tubing and/or the presence of air inside the
tubing.
Inspect, and tighten if necessary, each Luer fitting (do not use
instruments to tighten the fittings).
5.
Inspect the tubing that returns to the pump from the patient.
6.
Examine the saline bag to ensure that it has not been accidentally
compromised (for example, the spike may have damaged the bag wall).
7.
Inspect the tubing from the saline bag to the saline reservoir and the
pump.

Introduction
Use of the System
WARNING! PATIENTS MUST BE CONTINUOUSLY MONITORED.
Patients being treated with the System must be checked frequently (hourly)
when the System is operating. It is possible for malfunctions or misuse of the
System to result in patient injury or death.
The ZOLL Intravascular Temperature Management (IVTM™) System is
comprised of an external heat exchange system (Thermogard XP®) and an
IVTM™ endovascular heat-exchange catheter connected via a sterile heat
exchanger and tubing circuit (Start-Up Kit). These components together
comprise a patient temperature-regulation apparatus employing feedback
control. The catheter and the Start-Up Kit (its heat exchange coil, air trap, and
tubing) are single-use disposable devices.
This manual provides operating instructions for the System and the Start-Up Kit.
Catheter components are referenced where it is necessary to assure proper use
with the system components. Always refer to the catheter’s Instructions for Use
for additional specific information.
Operating Life
The operating life of the catheters may vary according to design as indicated by
the model designation. Always refer to the catheter’s Instructions for Use for
information about the catheter’s operating life.
The disposable components of the Start-Up Kit are designed for continuous use
for a period not to exceed seven (7) days on a single patient. After seven days of
use, all start-up kit components must be removed and replaced with components
from a new Start-Up Kit.
CAUTION! START-UP KIT LIFETIME IS SEVEN (7) DAYS.
The designed operating lifetime for Start-Up Kit components is seven (7) days
of continuous operation on a single patient. If a patient must be treated for a
longer period, a new Start-Up Kit must be installed in the System. Failure to
adhere to this time limit may cause injury to the patient.
Product designed for single use only. Do not resterilize or reuse. Do not alter
the Start-Up Kit in any way.
Potential risks with re-use of a single use device include but are not limited to:
Potentially life threatening infection
Toxic shock due to degradation of materials
Increased risk of thrombosis
Reduced heat exchanged power
Device failures

Introduction
Functional Description
The System can be described in terms of three major components: a
recirculating chiller, a sterile fluid roller pump, and a temperature control system.
The System is connected to the temperature-controlled catheter by two smallbore plastic tubes. One tube supplies temperature-controlled sterile saline
solution to the catheter, and the other tube returns the saline solution to the
System. The sterile saline is pumped through a continuous recirculating loop by a
peristaltic pump inside the console. The saline solution acts as an intermediate
heat-transfer medium between the patient and the System. Sterile saline is used
because it is biologically compatible with the patient and in the unlikely event of a
leak in the catheter, the possibility of harming the patient is reduced to a practical
minimum.
Patient temperature feedback is used to control the system. The patient’s
temperature is measured by an indwelling YSI 400 thermistor temperature
sensor. In response to the patient’s measured temperature, the System employs
both cooling and heating. Cooling occurs when the patient’s temperature is
above the set point target temperature. Heating occurs when the patient’s
temperature is below the set point target temperature. The amount of heating or
cooling power is proportional to the difference in temperature between the set
point target temperature and the patient’s measured temperature.

Power Indicators
An indicator lamp on the control panel is illuminated when power is switched on.
A second power-on indicator is mounted directly above the power switch on the
rear of the console.
Alarm Indicators
The System typically notifies users of alarm conditions in two ways. When an
alarm occurs, the screen displays an alarm message, and an alarm annunciator
produces an audible alarm tone (beep). The alarm tone can be temporarily
muted by the user, but it cannot be turned off.
If the nature of the failure prevents the System from displaying an alarm
message, the alarm indicator on the control panel will be illuminated.

Page 22
Introduction
Temperature Controller
The temperature controller uses input from the patient’s temperature probe and
the operator-selected patient temperature setpoint to regulate the coolant
temperature of the recirculating chiller. The temperature controller constantly
adjusts the coolant temperature by means of a closed-loop control system. The
operator enters a setpoint that represents the patient’s target temperature. The
controller cools or heats the coolant, in a range between 0º and 42º C (32º and
107.6º F) to optimally achieve and maintain the target temperature. The controller
constantly displays the measured patient temperature and the target
temperature.
An optional mode can command the controller to approach the target
temperature at a user-selected rate.
Temperature Probe Connectors
The front of the System console features two connectors, labeled “T1” and “T2”
which are used for connection to patient temperature probes. The primary patient
temperature probe is plugged into connector T1. The secondary probe is plugged
into connector T2.
Figure 2-4. Temperature Probe Connectors.
Pump
Sterile saline solution is circulated through the heat exchanger coil and the
catheter by a high-performance, compact roller pump. It pumps by peristaltic
action on the tubing installed in the pump head. The pump rotation speed is
accurately controlled by an electronic speed control system.

Introduction
WARNING! FINGER INJURIES
Be careful when inserting the pump tubing that you do not catch your fingers
with the roller.
When the System is operating DO NOT attempt to circumvent the safety
interlocks on the peristaltic pump lid. DO NOT place fingers or foreign objects
into the pump raceway when the pump is turning. The peristaltic pump has
sufficient torque to severely damage a finger.
If a tubing leak or failure occurs in the pump raceway, the saline solution will
cause corrosion in the moving parts of the rotor.
1.
Remove the pump rotor (refer to Pump Rotor removal instructions in
System Service Manual).
2.
Rinse the rotor in clean water and thoroughly dry the rotor.
3.
Apply a few drops of light machine oil to the moving parts of the rotor.
4.
Reinstall the rotor (refer to pump rotor installation instructions in System
Service Manual).
Figure 2-5. Pump.
Prime Switch
The prime switch is located on the right side of the pump. The switch is used to
operate the pump to prime the tubing with sterile saline solution from the saline
source. When the switch is held down, the pump runs; when the switch is
released, the pump stops.
