ASTOTHERM PLUS Instructions for Use
6 Product description
6.1 Introduction
ASTOTHERM PLUS consists of a stand-alone Warmer and optionally of the
additional active insulation ASTOLINE („S“-models).
ASTOTHERM PLUS is a device for specific heating of blood and fluids which are
delivered to the patients by transfusion, infusion or irrigation. The warming of the
liquid supports the prevention and therapy of hypothermia during or after surgery;
during longer procedures such as dialysis, hemofiltration, or apheresis the warming leads to a well-being. The applications of the ASTOTHERM PLUS therefore
include transfusion, infusion, dialysis, hemofiltration and apheresis.
The ASTOTHERM PLUS Warmer can be used to warm fluids administered to a
patient at flow rates of 0 to 6000 ml/h (i.e. 0 to 100 ml/min), see figures 1 to 4.
In the case of low flow rates, the re-cooling of the heated fluid on the way from
the warmer to the patient is limited by using the active insulation ASTOLINE („S“
models only). The heated flexible silicone body surrounds the infusion extension
on the way to the patient, ensuring that the part of the infusion line which would
otherwise be exposed to cool ambient air is insulated and heated. Its special
shape also enables infusions and transfusions to be observed all the way to the
patient.
The active insulation ASTOLINE and the infusion extension ASTOTUBE are
considered as applied part acc. to IEC/EN 60601-1.
6.2 Technical description
During operation of the Warmer heat is transferred from the internal heating
element to the heat exchanger. Infusion extensions can simply be inserted in the
circumferential groove. The heat from the heat exchanger is transferred through
the inserted infusion extension to the fluid to be warmed.
The temperature of the heat exchanger is monitored by a microprocessor
controlled temperature control system and by two independent alarm systems
designed to alert the operator to failure conditions and, if necessary, to switch off
the heating process automatically in the event of excessively high temperatures.
During operation, the mean temperature of the heat exchanger is displayed; this
is not equal to the temperature of the medium to be warmed. ASTOTHERM
PLUS neither regulates nor monitors/displays the current temperature of the
medium to be warmed. The temperature of the medium (fluid) depends on a
variety of factors, such as, but not limited to additional factors:
Room temperature and ventilation
Inlet temperature of the fluid (warmed-up or cold)
Flow rate
The heat protection sleeve (option) protects infusions from the effects of external
cold (e.g. air condition) and prevents heat being given off into the room.

CAUTION
Risk of hypothermia!
When ASTOTHERM PLUS is used, the patient’s body temperature must be
montitored at regular intervals.
The specified heating performance will only achieved by inserting the infusion
extension into the entire heat exchanger and, if applicable, in the entire length
of ASTOLINE.
The temperature control of the ASTOTHERM PLUS controls and monitors
the current temperature of the heat exchanger, but not the patient’s body
temperature.
If the ASTOTHERM PLUS cannot be started or if the patient's temperature
balance is insufficient, consider the use of alternative warming methods in
order to avoid or reduce hypothermia or to improve the patient's well-being.
Typical temperature curves are shown in the following figures.

WARNING
Risk of air embolism!
Be aware of the potential for air emboli when using a blood and fluid warmer.
Therefore prime all filters, lines and disposable sets before starting a
treatment.
Make sure all connections of the complete fluid stream are fixed tightly to
prevent fluid leakages and inadvertent infusion of air into the fluid stream.
When fluids are warmed up, it is possible that gas may evolve (bubble form).
Do not warm infusions containing soluted gas (e.g. bicarbonate).
Extreme care should always be taken to ensure that a bolus of air does not
pass to the patient.
WARNING
Risk of infection!
Use aseptic procedures.
WARNING
Risk of haemolysis!
Make sure that the infusion line is not kinked.
CAUTION
Risk of hypothermia!
When ASTOTHERM PLUS is used, the patient’s body temperature must be
montitored at regular intervals.
The specified heating performance will only achieved by inserting the infusion
extension into the entire heat exchanger and, if applicable, in the entire length
of ASTOLINE.
The temperatur control of the ASTOTHERM PLUS controls and monitors the
current temperature of the heat exchanger, but not the patient’s body
temperature.
If the ASTOTHERM PLUS cannot be started or if the patient's temperature
balance is insufficient, consider the use of alternative warming methods in
order to avoid or reduce hypothermia or to improve the patient's well-being.
Pressure losses can occur when infusion extensions are used
(depending on tube dimensions and flow rate).

10 Alarms and troubleshooting
In the event of device failure, two independent monitoring systems ensure the
safety against overheating. Except for the low temperature alarm, all alarms
switch off immediately the heating function. Thus, the overheating of the heated
liquid is surely prevented.
ASTOTHERM PLUS does not require continuous supervision by the operator, but
it must be checked at regular intervals (depending on the condition of the patient
status). Then the intended operator’s position is directly in front of the control
panel.
In case of failure of the equipment, possible injury to the patient is delayed and
the operator has sufficient time to provide alternative warming methods.
According to IEC/EN 60601-1-8 the alarms are defined as “Low Priority Alarms”.
The alarms are only triggered by technical alarm conditions (equipment faults).
The alarm signal is given visually and acoustically.

the test protocol (chapter 12.3 Test protocol)
This test is used to check the essential performance.
Absolutely avoid during this measurement influences from the
environment (drafts, heat radiation of other heat sources, etc).
Use if available the heat protection sleeve (slightly rotated so
that the measuring bore is freely accessible).
Clinical thermometers are designed as „immersion sensors“. In
order to achieve a sufficiently accurate measurement result,
the thermometer must be immersed deep enough (depending
on manufacturer and type). Because here only the metal tip of
the thermometer is used, usually the measured temperature is
slightly lower than the real temperature.

Portable and mobile RF communications equipment should be used no closer to any part of the ASTOTHERM PLUS,
including cables, than the recommended separation distance calculated from the equation applicable to frequency of the
transmitter.
Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and
"d" is the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, a should be less than the
compliance level in each frequency range b.
Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE1. At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the ASTOTHERM PLUS is used exceeds the applicable
RF compliance level above, the ASTOTHERM PLUS should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the ASTOTHERM
PLUS.
b
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
Recommended separation distances between
Portable and mobile RF communications equipment and the ASTOTHERM PLUS
The ASTOTHERM PLUS is intended for use in the electromagnetic environment in which radiated RF disturbances are
controlled. The customer or user of the ASTOTHERM PLUS can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the ASTOTHERM
PLUS as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at maximum output power not listed above, the recommended separation distance d in
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in Watts (W) according to the transmitter manufacturer.
NOTE 1: The compliance level between 80 MHz and 2.7 GHz is intended to decrease the likelihood that mobile/portable
communication equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in this frequency
range.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
