1. Introduction
1.1. Intended Use
LUCAS® 2 Chest Compression System is to be used for performing external cardiac
compressions on adult patients who have acute circulatory arrest defined as absence of
spontaneous breathing and pulse, and loss of consciousness.
LUCAS must only be used in cases where manual chest compression would be used.
LUCAS is only intended for temporary use.
This manual is a part of the Service Education Program that, together with hands-on
technical training, will provide the Service Technician with the knowledge to examine
and repair LUCAS.

3. The Function of LUCAS
3.1. Electronics System
3.1.1. The Battery
LUCASis driven by a rechargeable Lithium Ion Polymer (LiPo) battery. The battery can be
charged during operation by an external Power Supply, connected to a wall outlet, or with a
car power cable. You can also remove the battery from LUCAS and recharge it in a
separately sold battery charger of desktop model.
IMPORTANT: The battery must be connected even when the device is supplied by the
power supply.
The battery is mechanically keyed to LUCAS and the battery charger to make sure you get
the correct installation. The top of the battery has connections for power and
communication to the battery charger and to LUCAS.
The battery has built in intelligence to monitor the number of usage cycles and battery age to
tell the user when to replace the battery. The battery intelligence also monitors the battery’s
internal temperature.
The battery supplies power to the electronics and the electrical motor. The motor is
connected to the linear unit via a drive belt.
3.2.1. The Printed Circuit Boards
The electronics is divided into three parts that are situated on two separate PCB’s:
•The Control System that controls the motor with information from the user interface
and from the rotation and linear sensors.
•The Protective System that controls inputs and outputs and shut off in case of a
problem.
•The internal Battery Charger that controls the charging sequence of the battery.
There are two separate linear measuring sensors that monitor the movement of the Suction
Cup. One is for the Control System; the other one works as a reference to the Protective
System.
The User Control Panel is the user interface with which the device can be controlled and
monitored through six button switches and a number of LED’s. The User Control Panel is
situated on the hood and is connected to the protective/charger system that sends the
signals to the control system. For further details on the User Control Panel please read
chapter 2.7 in the Instructions for Use which also explains the different states on the Battery
indicator.
An electrical fan is situated at the bottom of the device for cooling the electrical motor and
other electronics. The fan starts when the internal temperature reaches 40°C and stops
when the temperature is below 30°C.
See pictures on the following page.

3.2. Compression Mechanism
The Drive Belt, driven by the Electrical Motor, drives the Carry Ball screw, forcing the carry
ball nut up and down.
The nut is fitted to a piston that moves the suction cup piston up and down.
The Decompression Spring reduces the upstroke force
The Suction Cup is adjusted to the patients’ chest with a servo aid system. It can easily be
replaced with respect to hygiene.

3.3. Components of the LUCAS® 2 Chest Compression System
LUCAS has two Support Legs that lock to the Back Plate with Claw Locks. The Support Legs
are foldable for convenient transportation.
The Claw Locks automatically lock to the Back Plate when LUCAS is pressed on to it.
To unlock the Claw Locks, pull the Release Rings.

4. LUCAS® 2Program Loader
LUCAS® 2 PROGRAMLOADER IS
SOFTW AREFOR UPDATINGTHE PROGRAMIN LUCAS. IT CAN ALSO BE USED TO
READ ERRORSAND
W ARNINGS FROMTHE DEVICE. THIS SECTIONEXPLAINSHOW THE SOFTWARE W ORKS.
4.1. Software Installation
Installation of a USB driver must be completed to connect to the Lucas device. Run the
application directly by clicking on the USB Driver icon. (This is only needed the first time the
LUCAS 2 Program Loader is installed, independent of which version. Then copy the file
(LUCAS2_V2X.exe) file from the media to the desktop, or to another location, and then
create a shortcut on the desktop.
4.2. Connect the Device
Connect an USB cable between the computer and the device, the connector is situated at
the lower left side of the Control PCB on LUCAS 2.2. (On LUCAS 2.0 and LUCAS 2.1 the
connector is situated at the top left corner of the Protective PCB, according to picture below.)
Start the device.
Start the software by executing the .exe file for the device you are working on. For example,
if you are working on a LUCAS 2.2, you will execute LUCAS2_V22.exe file.

4.3. Using the Software
When the program is started this window should appear:
The picture shows software LUCAS2_V21B.
Normally the software detects the device at start. If not, set the USB Port setting to AUTO
and then Click “Init COM”.
Now the information about the device should appear in the designated windows.

The present Errors and Warnings appear in each CPU’s box window.
It’s also possible to set the Device ID, Time and Date (uses the PC time and date).
4.4. Update the Program
To update the program, click Program in the upper right corner.
The programming process will start and update the software for each CPU.
When all three CPU’s are updated this window will appear where you are prompted to
make a Linear Sensor Calibration. Before you click the Start button please make sure that
nothing can influence the movement of the suction cup and that the device is in its upright
position.
Click START.
Now the Calibration process will start. The progress can be followed in the Control
CPU’s window.

LUCAS® 2 Chest Compression System – Service Manual
3323809-001, © 2017 Physio-Control, Inc.

When the calibration is finished you’ll get this message:
Now the calibration result is shown in the lower right corner.
Click Store View to print and save the result.
4.5. Failed Calibration
If the value for Control exceeds 6% or if the value for Protective exceeds 3.1% the device
will make an alarm and an error code will be shown in the Control CPU window.
If this happens, mute the alarm, check that nothing interferes with the movement of the
suction cup and that the device is upright. Click POTCAL to make a new calibration.
If also the second calibration fails it might be necessary to replace the Compression Module.
