Service policy.
1.1 Service policy.
The Cardio-Aid® defibrillator line sets a new standard for serviceability. The
objective is to exploit a distributed service strategy, where extended servicing
of the defibrillator can be handled by either the certified distributor or the
biomedical department in the hospital, or by the possibility of remote trouble
shooting and downloading of software directly from Artema.
®
The service policy for the Cardio-Aid
levels:
1. Field service (at hospital):
Replacement of the battery.
Software and voice prompt update from memory card.
Calibration via the built-in Service Menu.
2. Service by authorized and certified distributor.
defibrillator can be divided into three
Software update from memory card, servicing, fault finding and calibration from the built-in Service Menu or remotely from a PC.
Replacement of spare parts and main components.
Upgrading with optional features.
3. Factory service.
Full service at the Artema factory.
The range of service products includes:
1. A PC service kit for certified distributors, for remote servicing, calibration
and fault finding. The kit includes software and the necessary hardware
for connecting a PC to the defibrillator, see Chapter 9 – Defi program. and
Chapter 10 – Spare parts.
2. Memory card for download of software and voice prompts updates.
3. All printed circuit boards, cables, main components, labels and essential
cabinet parts. See Chapter 10 – Spare parts..
4. Service kits for updating the defibrillator with the optional printer or
change of the defibrillation means (Pads or Paddles)
5. Tools and test equipment that is to be used when servicing the defibrillator. See Chapter 10 – Spare parts.
Thus this manual is developed to support diagnostics and support at system
and printed circuit board levels. The distributor and authorized service dealer
should keep appropriate stock of spare parts to support this principle. Printed
circuit boards, which need repairs, must be returned to Artema.

The product.
1.2 The product.
The Cardio-Aid® is a defibrillator intended for use inside a hospital.
Primary use for emergency situations by inexperienced defibrillator operators
but also to be used by experienced users for defibrillation, monitoring, inhospital transport and cardio version.
The Cardio-Aid® is typically mounted on a shelf, emergency trolley or hanging on a wall mount device or at the end of a hospital bed during transport.
®
The Cardio-Aid
modes.
The Cardio-Aid® can be delivered in two different version.
V1.0 Manual/Semi automatic defibrillator with pads
V1.1 Manual/Semi automatic defibrillator with paddles
incorporates semi-automatic and manual defibrillation
The Cardio-Aid® has a built-in main power supply and an internal battery for
full operation when disconnected from the main supply.
The Cardio-Aid
®
has a PCMCIA slot for:
PC remote control via a serial card.
Software update via a memory card.
Storing event logs on a memory card (in the future).
Cardio-Aid® includes also (optional):
A built-in thermal paper printer for generation of paper strip documentation,
A build-in Pacer module for external pacing.
The accessories for the Cardio-Aid® include internal paddles (spoons),
defibrillation electrodes/pads, printer paper, PCMCIA memory cards,
accessory bag, Bed hook, Trolley mount, ECG cables, Service kit etc.
1.2.1 Philosophy of the Cardio-Aid®.
The philosophy of the Cardio-Aid® is to fulfil the requirements from two different user groups.
1.2.2 The first responder.
Typically a less experienced person in the resuscitation process e.g. a nurse,
hospital technician or other non medical staff. The less experienced users,
only trained in basic life support and how to use an AED, need an extremely
easy to use defibrillator giving as much guidance and safety as possible.
1.2.3 The experienced
Users from the anesthesiology or cardiology dept. joining the resuscitation
team at a later stage of the process. The experts need the more advanced

functions as manual selection of energy levels, synchronized defibrillation for
cardioversion, monitoring and external pacing.
The operation is optimized for the two types of users based on the 1-2-3 step
approach accepted in the market today.
1.2.4 Semi automatic mode.
Semi automatic mode is intended for the first responder, who will be guided
through the resuscitation process using the Cardio-Aid®. This is done
through short advisory messages shown in the display assisted by voice
prompts. The ECG-signal from the patient is analyzed by the Cardio-Aid®,
and the result is presented to the user. The user is guided through the
sequence of shocking, checking for signs of circulation and performing CPR.
To use the Cardio-Aid® in Semi automatic mode, the user will only need to
press the Power On/Off key (1) to turn the Cardio-Aid
(2+3) key to analyze and deliver the shock. See the D.F.U. (Directions for Use)
for details.
®
on and the Action
1.2.5 Manual mode.
Manual mode is intended for the experienced user. The ECG signal is analyzed in the Cardio-Aid® and the result is presented to the user. The user can
act on the analysis results, or make a defibrillation whenever it is needed. To
use the basic functions of the Cardio-Aid
®
in manual mode, the user will
only need to do the following. Press the Power On/Off (1) key to turn the Car-
®
dio-Aid
on, open the cover covering the expert keyboard to get access to
the energy selection keys and to select manual mode with the Manual key if
not already selected in the configuration menu. Select the desired energy
with the Energy up/down on the expert keyboard or on the paddles. Activate
the Charge key (2) and the Shock keys (3) on the paddles or the Action (2+3)
keys if pads are used to charge and deliver the shock. See the D.F.U. (Directions for Use) for details.
1.2.6 Pacer.
The user will be able to pace the patient externally by placing defibrillation
electrodes/pads on the chest of the patient. The ECG is still analyzed by the
Cardio-Aid® and a message is presented to the user if a shockable rhythm is
detected. To use the Cardio-Aid
press the Pacing key to enter pace mode, adjust pace rate with the Pace rate
keys, adjust the pacing current with the Pace Current key and start the pacer
output with the Pacer On/Off key. The pace mode (fixed or demand) can be
selected in the user menu. See the D.F.U. (Directions for Use) for details.
®
in Pace mode, the user will only need to
1.2.7 Test mode.

compared with the selected energy, and a record is printed.
Furthermore a simulated ECG signal can be shown on the display for demonstration and training purposes. Access to the simulated ECG signal is protected with a secret key to be activated during power on. See the D.F.U.
(Directions for Use) for details.
1.2.8 Service and Configuration menus.
The configuration and service menus are dedicated to the technician in
equipment set-up and service situations. The configuration and service menu
are not used in the resuscitation process.
Accesses to the menus are protected with a secret key to be activated during
power on. See the D.F.U. (Directions for Use) and Chapter 7 – Verification and
Test. for details.
1.2.9 General user interface principle.
To keep the user interface extremely simple for the inexperienced users, the
advanced functions like: Mode selection, Manual energy selection, Alarm
system, Synchronization, Pacemaker functions and User set-up menus are
hidden underneath a plastic cover. To access the functions the cover is easily
opened.
®
The keys on the Cardio-Aid
are dedicated keys and have only a single function. The Print key can, however, be used in conjunction with Lead key to
activate the lead scan function and together with the Event key to make an
event report printout. Keys that control parameters with several settings toggle through the possible values, and wraps around when pressed with the
last setting of the sequence showed. The menu function is entered and exited
through the same key.
1.2.10 The Cardio-Aid® design.
The Cardio-Aid® consists of a cabinet housing the mechanical and electrical
parts. The front encompasses a display, a keyboard, High Voltage connector
and ECG connector. Display and keyboard are used for implementing the
®
interaction between the user and the Cardio-Aid
grated sound and voice-prompt system. The paddle holders with integrated
test connection are placed on each side, making access to the paddles easy.
The printer is placed on the left side of the cabinet. A PC card slot is placed
on the right side of the cabinet. The internal battery compartment is placed
behind the sternum paddle holders on the left side. A mains supply connector
which includes the mains fuses is placed on the rear of the cabinet. An
accessory bag can be mounted on the rear of the cabinet.

1.3 Installation.
The Cardio-Aid® is intended for In-hospital use. To support the installation of
the defibrillator in different environments within the hospital a number of
suitable applications are made available to ease the mounting process.
The development of the Cardio-Aid® was not only aimed at a functional
design but also on a mechanical well balanced construction that can be used
as is. However, in order to provide the user with suitable mountings solutions
there has been developed a Trolley, Wall and Bed mount.
1.3.1 Trolley mount.
Basically 3 types of standard mounting scenarios are seen for mounting a
defibrillator on a trolley.
1. On a defibrillator swing arm, that is “raised” approximately 20-30 cm
above the main chassis of the emergency trolley.
2. On the top work base of an emergency trolley.
3. On the top plate of an equipment trolley.
Page 8, Artema MEC. A/S CA200, Service manual No. 95900-B
Chapter 1 – Introduction.
Installation.
Requirements:
It is important that the defibrillator can be secured properly from sliding,
tilting or dropping on the floor, while leaving the defibrillator controls unobstructed. Furthermore, it must be easy to detach the defibrillator from the
trolley.
Solution:
An easy to use metal plate that can be mounted on any flat surface. When
properly mounted the Cardio-Aid® slides onto the plate and uses the cut-
away sections for the positioning of the four feet.
1.3.2 Wall mount.
The Cardio-Aid® must be positioned in an upright position as close to the
wall as possible.
The wall mount is identical to the trolley mount, without any mechanical or
electrical connections. The wall mount will secure the Cardio-Aid
tor from sliding, tilting and dropping on the floor.

3.1.1 Power management.
The internal Power distribution in the Cardio-Aid® takes place in two ways:
From the AC inlet placed on the rear side.
From a built in battery pack.
3.1.1.1 Power Supply board.
The Power Supply is a combined power factor controller and DC/DC converter.
The Power supply is designed to accept inputs levels from 100-240VAC and
to deliver a constant output power up to 60W and a peak power up to 200W.

The AC from the inlet is feed via the input filter network to the AC/DC converter, which is a combined power factor controller and rectification circuit.
The converted DC voltage supplies an isolated DC/DC converter, which delivers a regulated 19VDC-output voltage, used as system supply for the differ-
ent circuits' board inside the Cardio-Aid®.
The Power supply is protected against overload by help of two high breaking
capacity fuses placed into the AC inlet connector onto the rear side of the
®
Cardio-Aid
.
Output of the converter is electronically overload and overheat protected. If
an over-voltage is detected, the unit automatically will close down. Normal
operation is restored when the main voltage has been disconnected from the
AC inlet for a few seconds.

3.1.3 Multi output converter.
The system or battery voltage from the merging circuits supplying the converter.
The converter outputs' supplying the different circuits locally on the Defi
board as well the Processor board with following voltages:
+5V dc.
+12V dc.
-28V dc.
2 x ±15V dc.
+ 13V dc. (only used for the printer).
The 15VDC outputs are galvanic isolated from the other outputs to ensure
the patient isolation between the ECG amplifier modules and other circuits.
The converter is over voltage protected and will latch the converter off in
fault conditions.
3.1.4 Battery fast-charge and energy monitoring.
The charging circuit ensures a comprehensive control of the battery charging
process to secure long lifetime for the battery. The circuit controls the charge
time and monitor the temperature in the accumulator-cells during charging.
The Defi controller monitors the actual energy supplied to and from the battery pack and data is used to inform the user about battery capacity.
A two-colored LED indicates the battery charge status on the front of the
Cardio-Aid®. Green indicates that the battery is fully charged and yellow
indicates battery is charging.
3.1.5 Defi Controller and safety logic.
The Defi controller and safety logic is for safety reasons designed as a twochannel system, where the Defi board controls the primary channel and the
Processor board the secondary channel.
The Defi controller is based on a single chip processor, which include serial
ports for communication locally onto the Defi board, parallel ports for interfacing to the processor board and other digital controls.
Any safety critical parameter analogue as well digital is monitored by the
two-channel system. If any of these parameters is exceeding defined limits,
the limits is brought into a safe state and an error message will be shown at
the display.
3.1.6 Shock gate.
The high voltage relay is switching between charging of the high voltage
capacitor and discharging energy to the patient. Both the relay and the
capacitor are placed outside the Defi board into the moulded inner chassis.
To control the relay the shock gate merges the shock control signals from the
two channels.
Artema MEC. A/S CA200, Service manual No. 95900-B, Page 19
Chapter 3 – Technical description.
Block description.
For executing a shock discharge both signals must be present at the same
time, which secure that both channels must be fully functional to deliver a
discharge.
3.1.7 High Voltage Generator.
The system voltage from the power merge circuit supplies the high Voltage
Generator, which is controlled by the safety logic.
In monitoring mode the generator is disabled and the high voltage capacitor
is shortened by a discharge/drain resistor placed onto the Defi board.
When a high voltage charging sequence is initiated, the primary channel
enables the generator and controls the voltage charging of the capacitor. The
second channel acts as a safety processor during the whole defibrillation
process.
3.1.8 ECG interface.
The Cardio-Aid® has two ECG modules placed onto the Defi board.
The Defi board acts only as a gateway for the serial communication between
ECG modules and the processor board. The communication takes place by
help of opto-coupler, to secure the patient isolation.

3.1.12 Real Time Clock.
The real time clock is an integrated circuit which also contains a lithium battery and crystal clock. The lifetime of the lithium battery is more than 10
years.
The real time clock is integrated with an intelligent controller, which may
initiate a “Wake Up Test” by itself, if specified in the Cardio-Aid® configura-
tion menu.
3.1.13 Voice and sound generator.
The voice table for the voice processor is transferred via the Main processor
DMA channel. The converted voice data is merged together with volume and
sound data by an electronic potentiometer and fed to the loudspeaker.
3.1.14 Watchdog.
A watchdog circuit ensures that the program execution on the Cardio-Aid®
is fail-safe, by supervising the processor.
The processor must address a specific memory location in a certain interval
and if not, the Watch dog will time out and generate a global reset to several
®
circuits of the Cardio-Aid
A Watch-dog reset caused by an error will power off the Cardio-Aid
.
®
and an
error code may appear in the display next time the Cardio-Aid® is powered
on. After an error occurs, a fault LED placed on the front is flashing as well as
a piezo speaker will start beeping.
3.1.15 Defi controller interface.
To communicate with the defi processor, the processor sends and receives
command data via an eight-bit bi-directional port. A few additional safetycontrolling lines are fed separately to the Defi board.
3.1.16 ECG and Printer interface.
Communications to and from the Paddle and Cable ECG amplifier is implemented as serial signals via the Defi board.
The communication signals are feed to the processor via a separate UART on
the board and ECG signals processing takes place by the processor.
3.1.17 PCMCIA interface.
The interface is primarily used for storing obtained patient data onto a memory card.
The interface is also used when updating the Main and Basic software by
downloading either from a memory card. See also 4.2.3 PCMCIA connector.,
and 9.2 Equipment needed..
