The PRIMEDIC™Defi-Monitor is an external defibrillator
with integrated ECG monitor and on-line printer. The
defibrillator can be synchronized with the ECG enabling
synchronous cardioversions.
The device series is organised modularly. Several models are
available:
PRIMEDIC™Defi-Monitor
ECO 1 low cost model
DM 1 basic model
DM 3 with pulsoximeter
DM 10 with module slot
DM 30 with pulsoximeter and module slot
The modules Pacer, I/D (internal defibrillation) and R/D
(free-handed defibrillation) can be connected to the module
slots of DM 10 and DM 30.
The design of the PRIMEDIC™Defi-Monitor allows quick
and safe use in cases of emergency. All function units and
operating elements are based on the following features:
•clear structure of the function units
•reduction to the essential functions
•logical user guidance
•clear, self-explaining operating elements
•ergonomical design
•retrofitable functions, due to the modular design
At the models DM 1, DM 3, DM 10 and DM 30 the
ECG monitor has a high resolution graphic EL display
ensuring clear screen contrast even under problematic
lighting conditions.
The ECG monitor can be moved upwards and downwards
allowing a perfect viewing angle towards the ECG shown,
e.g.:
•in lying position outdoors
•in upright position with deep installation places in
ambulances.
As for the device versions DM 3 and DM 30 a continuous
non-invasive measure of the functional oxygen saturation of
arterial haemoglobin (SpO2) is possible. The PRIMEDIC™
monitor is provided with a high-quality measuring module
from NELLCOR PURITAN BENNETT Inc.

Instructions for use PRIMEDIC™Defi-Monitor ECO 1 / DM 1 / DM 3
70 19499 / 05.03
Together with the in Capter 6.2 (Selection of correct SpO2
sensor) adviced sensors, a continuous monitoring of adult or
paediatric patients is possible. Parallel to the measurement in
% a continuous pulse curve is displayed in the monitor. This
can be documented by the use of the high resolution printer.
During the measurement of the oxygen saturation, alarm
thresholds can be activated to indicate changes in the
patient’s condition.
The printer can be used to document the monitoring as well
as to record the emergency situation (the 5 s before and 5 s
after every shock).
The defibrillator allows safe and extremely quick use:
•Charging time for 100 joule approx. 1 s (*)
•Charging time for 360 joule approx. 5 s (*)
(*) = when accumulator capacity is 90 % of nominal value.
A module slot is provided at the sides of models DM 10 and
DM 30, where e.g. a pacer module may be inserted,
which is particularly operator-friendly. In contrast to common
pacers the paddle does not have to be removed in order to
connect the pacer- / defibrillation cable. With PRIMEDIC™
pacers the pacer- / defibrillation cable is simply attached to
the module. If the pacer- / defibrillation cables are
connected, the paddle electrodes are switched-off.
If during the pacer process a defibrillation is necessary, a
shock may be released via cushion electrodes. The release
buttons of the module control the charging of energy and the
release of a shock. Also without the pacer being active free-
handed defibrillation may be carried out with the cushion
electrodes.
If the pacer is not needed and the user does not wish to apply
the energy via paddle, the R/D module may be used. To this
module the cushion electrodes for the free-handed
defibrillation are connected.
By means of the I/D module for internal defibrillation the
internal electrodes can be connected via a sterilised patient
cable. In case of working at an open thorax a wide range of
internal electrodes is available.
The power supply of the PRIMEDIC™Defi-Monitor is
provided by changeable accumulators with NiCd cells. The
applied charging electronics corresponds to the latest
technology thus assuring a maximum service life of the
accumulators used.

Instructions for use PRIMEDIC™Defi-Monitor ECO 1 / DM 1 / DM 3
19499 / 05.03 71
In rest position the PRIMEDIC™Defi-Monitor can be
inserted into a charging unit. Wall mounting or mounting into
a vehicle is possible by means of various adapters (optional).
In an emergency case the PRIMEDIC™Defi-Monitor can
be released easily and quickly with one hand.
The electric connections (mains voltage or DC on-board
voltage) are fitted in the charging unit. The charging unit also
supplies the power for the accumulator charging.
A comfort version of the unit is available as option allowing to
charge a second changeable accumulator. When using the
comfort version with Accu-Care function the accumulator
receives best maintenance which prevents the problematic
memory effect. Retrofitting of all standard charging units with
the Accu-Care option is possible. The PRIMEDIC™Defi-
Monitor can also be operated while sitting on the charging
unit. For safety reasons the accumulator has to be connected
during operation to avoid removing the defibrillator from the
charging unit without accumulator in case of emergency.
A variety of accessories are available.
3. Preliminary measures
3.1 Accumulator charging
The changeable accumulator has to be charged before first
use of the PRIMEDIC™Defi-Monitor.
Lock the changeable accumulator at the provided and
marked location from the side in its position (see also section
9.1).
Then insert the PRIMEDIC™Defi-Monitor into the
PRIMEDIC™Defi-Charger. The green LED (58) lights up to
indicate that power is supplied to the charging unit (mains or
on-board voltage).
When the accumulator needs to be charged the charging
electronics starts the charging process, this indicated by the
charging LED (57) of the charging unit. At the end of the
charging procedure the charging LED (57) goes off.
Caution:
A completely discharged battery has to be recharged for at
least 45 minutes. A too short charging duration may lead to a
wrong interpretation of the battery charge by the device due
to the nature of the battery. The battery charge monitor in the
display will falsely indicate a full battery. A safe operation of
the device under certain circumstances will not be
guarantied.

19499 / 05.03 73
When calling up the set-up menu the first menu item is
marked. To change e. g. the time move the cursor
downwards by actuating DOWN (24) one or several times
until the menu item time is marked. Select the menu item
time by actuating OK (28). Then the cursor moves to the
hour which is changed by actuating UP (21) or DOWN (24).
Confirm the correct setting with OK (28). The cursor then
moves to the minutes which can be changed in the same
way as described. When confirming with OK (28) the cursor
returns to the menu item time. Now you can realize further
changes in the same way as described in the example time.
To quit the set-up menu move the cursor to the menu item
END by means of UP (21) or DOWN (24) and confirm with
OK (28).
Then the PRIMEDIC™Defi-Monitor returns to monitoring
operation.
Note:
If during the setting of the menu parameters the defibrillator
has to be used immediately because of an emergency the set-
up menu can be terminated immediately by pressing ENERGY
(32).
4. Operation of the defibrillator
4.1 Switching the defibrillator on and off /
self-test
Press ON / STAND-BY (30) shortly to switch on the
PRIMEDIC™Defi-Monitor.
To switch off, press ON / STAND-BY (30) for approx. 2 secs.
During switch off procedure an acoustic signal is given. This
time was chosen to prevent the device from being switched
off accidentally. Energy that possibly has been charged for the
defibrillation will automatically be discharged internally.
Note:
The complete device is switched on and off with ON/
STAND-BY (30). Thus the functions of all components can be
used without loosing time.
When starting an internal self-test will be executed to check
important functions and signal devices. All LEDs of the
defibrillator light up for approx. 2 seconds. Be sure that all
LEDs are active. During this time a warning buzzer has to be
on as well. It is important that the buzzer functions.

Instructions for use PRIMEDIC™Defi-Monitor ECO 1 / DM 1 / DM 3
74 19499 / 05.03
Attention:
If one or several LEDs or the warning buzzer do not function,
the defect has to be eliminated immediately.
4.2 Synchronous and asynchronous
operation
When switching on the PRIMEDIC™Defi-Monitor the
defibrillator is automatically in asynchronous operation.
Press SYNC (34) to select synchronous operation of the
defibrillator (cardioversion) if required by the emergency
situation.
LED (33) signals the synchronous operation. In addition, the
note "SYNC" is displayed on the ECG monitor.
After a synchronous discharge (cardioversion) the defibrillator
switches back to asynchronous operation.
Note:
During synchronous operation ECG markings are shown on
the monitor. For safe synchronous operation these
cardioversion markers must appear in every QRS complex
with a R-peak. A clear, artefactfree ECG signal with sufficient
amplitude is essential.
If there are no markings shown on the ECG monitor, the
amplitude probably has to be changed by means of SIGNAL
AMPLIFICATION or a lead with improved signal quality has to
be selected.
Note:
Do not use the paddles but the external ECG patient
electrodes for the ECG recording during synchronous
operation. Otherwise artefacts can be caused when moving
the paddles which leads to faulty synchronization.
Note:
The delay time between the recognition of a QRS complex
(synchronous pulse) and energy discharge is less than 60 ms.
Attention:
Before releasing the cardioversion check on the monitor
whether the cardioversion markers are clearly related to the
R-peaks and do not react e. g. to pacemaker pulses or
artefacts.

Instructions for use PRIMEDIC™Defi-Monitor ECO 1 / DM 1 / DM 3
19499 / 05.03 75
4.3 Energy selection
Press one of keys (32) to select the energy. LED (31) located
directly above the key pressed lights up to acknowledge the
energy setting. In addition the selected energy step is
indicated on the monitor.
Note:
The energy step required for the defibrillation / cardioversion
depends on the patient, its body height and weight and its
condition. For information please refer to appendix A2.
An energy step selected by mistake can be changed by
pressing the correct key with the required energy step. This is
also possible if energy has already been charged for
defibrillation. When increasing the energy step the missing
energy is added. When decreasing the energy step the
excessive energy is discharged in small steps.
4.4 Energy charging
The selected energy can be charged by pressing one of the
release buttons (10) or (12) and thus made available for the
shock.
Then the energy will be charged quickly. LED (45) flashing
indicates the charging procedure. The charging time depends
on the selected energy step and the available accumulator
capacity. Charging the defibrillator up to 100 joule takes
approx. 1 second, charging up to 360 joule takes about 5
second. In case of a partly discharged accumulator the
charging time may slightly be longer. See also technical data.
After the charging the energy will be available for 15 seconds
which is signalled by a permanent signal and the lighting up
of the OK signal (35). The remaining time is simultaneously
indicated on the monitor. If there is no defibrillation during
this time, an internal safety discharge will be executed.
During this time the energy charged can be changed again if
required (see section 4.3). After the change, the energy is
available for another 15 seconds for defibrillation.
Should an error occur during energy charging, an intermittent
warning signal and the Attention LED (36) will be on.

Instructions for use PRIMEDIC™Defi-Monitor ECO 1 / DM 1 / DM 3
76 19499 / 05.03
Attention:
If the message „load accumulator“ appears at least 5
discharges with maximum energy are available, in this case
the Defi-Monitor should be placed again as fast as
possible on the charging unit.
Attention:
If the ATTENTION LED (36) lights up the function of the
defibrillator can be tested by switching-off and then on again
with the help of a self-test. When the signal goes out, the
defibrillator is ready-to-use.
Attention:
If the ATTENTION LED (36) is still on after switching off and
on again, the malfunction must be eliminated immediately.
4.5 Positioning of paddles
The paddles must be positioned along the cardiac axis.
APEX paddle (9) hast to be positioned in the left chest area,
on the axillary line above the apex of the heart.
STERNUM paddle (13) hat to be positioned in the right chest
area, below the clavicle.
4.6 Discharging of energy (shock)
Press release buttons (10) and (12) at the paddles
simultaneously to discharge the energy.
In case of asynchronous operation energy will be discharged
immediately after simultaneous depression of buttons.
In case of synchronous operation both release buttons (10)
and (12) have to be pressed down simultaneously until the
moment for the cardioversion is reached. During this time an
intermittent signal will be on.
No cardioversion will be released, if during discharging the
release buttons are let go off.
The energy is discharged internally if no synchronization takes
place within 3 seconds while keeping the release buttons
pressed down. Thereafter, the PRIMEDIC™Defi-Monitor
returns to asynchronous mode.
During the shock the ECG input will generally be overloaded
for a short time. The PRIMEDIC™Defi-Monitor will supply
a stable ECG baseline already after approx. 1 second after the
shock so that the defibrillation success can be seen
immediately.

Instructions for use PRIMEDIC™Defi-Monitor ECO 1 / DM 1 / DM 3
19499 / 05.03 77
Attention:
Before releasing the cardioversion check on the monitor
whether the cardioversion markers on the monitor are clearly
related to the R-peaks and do not react e. g. to pacemaker
pulses or artefacts.
Attention:
Both paddles have to be pressed on the thorax by applying a
pressure of approx. 100 N in order to ensure safe energy
transmission and to avoid damaging the skin under the
paddles.
Attention:
Please insure that there is no contact or conducting gel
between the paddles.
Attention:
Before and during the discharging of energy all persons
attending to the resuscitation have to step back and any
contact with patients or conducting parts (e. g. stretcher) has
to be avoided. Remove all connected devices without
defibrillation protection from the patient before energy is
discharged.
4.7 Paediatric paddles
Electrodes with smaller electrode surface have to be used for
the defibrillation of children. The paediatric paddles are
integrated in the paddles for adults. Remove the large
electrodes from both paddles by turning counterclockwise.
Attach the paddles for adults to the paediatric electrodes by
turning clockwise.
Note:
Clean the paediatric paddles after use before attaching the
paddles for adults.
Attention:
Attach the paddles for adults firmly to ensure safe contact of
the paddles for adults.

The ECG graph can be realized in two ways:
1. via paddles
2. via external ECG patient cables.
The paddle lead is automatically active after switching on the
PRIMEDIC™Defi-Monitor which is indicated by a paddle
symbol on the monitor.
The monitor cannot be switched to the standard leads if no
external ECG patient cable is connected.
The standard leads can be used if an ECG patient cable is
connected. Press LEAD SELECTION (22). Lead II is
immediately active. Press LEAD SELECTION (22) to switch
between the possible leads I, II, III, aVR*, aVL* or aVF*. The
selected lead is shown on the monitor.
To switch back to lead via paddle electrodes press PADDLE-
LEAD (21) regardless whether ECG signals are available via
the external patient cable.
The monitor automatically switches to paddle lead when
pulling out the ECG patient cable from the input socket of the
PRIMEDIC™Defi-Monitor during the monitoring.
Note:
The PRIMEDIC™Defi-Monitor switches off automatically
when no ECG is shown or no key is pressed for 15 minutes
while the device is switched on. Approx. 30 seconds before
switching off an acoustic signal is given. By pressing any key,
the switching off routine is interrupted.
Note:
If the paddle lead is selected and the paddles are not
attached to the patient, an intermitting line with the message
„Electrodes open“ will be displayed in the monitor. As soon as
the paddles are attached to the patient, the recorded ECG
signal will be displayed in the monitor.
