1. General Introduction
CardioServ Semi-Automatic and Manual
There are 2 CardioServ models: the semi-automatic and the manual defibrillator. Both models are available with a pacemaker and SpO2.
The manual CardioServ is a defibrillator designed to deliver synchronized and unsynchronized shocks. This requires the user to trigger capacitor charging and shock delivery manually.
The semi-automatic defibrillator is equipped with analysis software, which monitors the ECG
for arrhythmias (fibrillation and ventricular tachycardia). When the analysis is started by
pressing a key the ECG is analyzed. If the result of the analysis is positive, the capacitor is
charged to the preselected energy level. The semiautomatic operating mode can be terminated by pressing a key or inserting the dongle.

3. Functional Description
The Therapy System CardioServ comprises a defibrillator, a monitor ( LC display 240 * 320
pixels ), a printer and a power supply unit. These components are arranged in a casing. It is a
compact unit, which can also be implemented using a 230-V power supply system, even
without a battery. The unit has a pulsed 140-mA standard charge for the battery. Additional
versions available have an external pacemaker and an SpO2 module, separately or combined.
The Defi is switched on by turning the rotary switch to position ECG or energy levels automatic sequence 2 ... 360 J.
Following a self-test, which tests
- RAM data store
- ROM program memory
- Watchdog / Reset
- EEPROM permanent memory
- Display all Pixels on / off
- Time base of internal quartz crystal
- Energy charge from last shock
- Defective charge or Defib keys
- Position of energy selector switch
- Connected electrodes
- Pacemaker
- SpO2
the Defi is ready for operation. If an error arises, depending on the severity of the error, the
Defi is either on standby or not. Serious errors are watchdog, ROM or RAM errors. In the
case of minor errors, an error message appears, but the instrument can be rendered operative by pressing a key.
The Defi shock is delivered via exchangeable paddles. This permits the use of different electrodes, i.e., in addition to conventional electrodes, large-surface adhesive electrodes or internal electrodes, for example. Adhesive electrodes are used for the pacemaker. The CardioServ also has Start and Trigger buttons on the instrument.
The charge operation is actuated with the Charge key on the apex electrode (for internal and
adhesive electrodes on the instrument). During the charge operation, the accumulation of
energy is registered and when the selected energy level has been reached the energy to be
released appears on the display. An acoustic and visual display on the monitor indicates the
configured energy level has been reached. When the battery is fully charged or with linepower operation, charging at 360 J should take about 8 s.
227 483 02-B SA(e)-98.05
Marquette Hellige GmbH CardioServ V.4 Page 12
Servicing Instructions
The buttons on both electrodes are pressed to trigger the defibrillation pulse (safety two-hand
operation). This means that the button on the apex electrode (or the corresponding one on
the instrument) has two functions:
- start the charge operation
- trigger defibrillation (together with the Trigger button)
The type of electrodes connected are recognized and, in the case of internal electrodes, the
energy is automatically limited to 50 joules.
Following defibrillation, the energy released is displayed on the screen for 6 seconds. Documentation output is by the printer.
The defibrillator has three operating modes:
* synchronized defibrillation (cardioversion)
* unsynchronized defibrillation (emergency therapy)
* semi-automatic (emergency service)
Cardioversion (operating mode Sync) can proceed either via the paddles or a patient cable.
The operating mode Sync appears on the display and Sync marks are superimposed on the
display. Following cardioversion, for safety reasons, the CardioServ switches automatically
over to the unsynchronized operating mode, i.e., before each cardioversion the instrument
must be switched over to Sync.
The Defi can be configured for semi-automatic operation in three ways:
* As a semi-automatic instrument only (defibrillation only possible via analysis)
* Semi-automatic instrument which can be toggled to manual mode by pressing a key
* Semi-automatic instrument which can be reset into manual mode using a dongle
ECG signal pick-up is possible via the paddles or ECG cable. ECG is output on the LCD
display or by the built-in 50-mm printer.
A safety device ensures the discharge of the storage capacitor in the following situations:
- when defibrillation is not triggered 30 seconds after storage operation is complete,
- 0.2 seconds after triggering defibrillation,
- immediately after switching back the energy selector switch during or after storage,
- when the battery voltage drops below a certain level,
- when the selected energy level still has not been reached after 32 seconds.
When switching to a higher energy level, the energy deficit is supplied by recharging.

Servicing Instructions
Pacemaker
The pacemaker is a transthoracic pacemaker operating in the Demand and Fix mode.
- Pulse width 40ms (20 ms)
- The frequency is between 0...180 P/min (> 150 P/min only 20ms pulse width)
- The current is between 0...200 mA
- Adjustment is in 5-unit intervals.
The pacemaker is operated using 6 keys on the control panel. One key switches the pacemaker on, one key changes the operating mode, the other keys are used to adjust the frequency and current. The defibrillator cannot be disabled as long as the pacemaker is
switched on. The adhesive electrodes of the Defi are used to release a pulse. This ensures a
rapid switch from defibrillator to pacemaker and back again.
SpO
2
SpO2 is based on one of the modules manufactured by Nellcor (MP204). This module is
located on the PCB Analog and receives its power supply from the latter. Measurement of the
oxygen saturation level and pulse frequency is made by this PCB.
Pulse frequency from 0...250 P/min
Saturation from 0...100%
We display the plethysmogram, saturation level and, when selected, the pulse frequency
instead of the HR.
Control options:
A battery charge check is performed under load application. The message charge battery
on the display means the battery needs recharging. At least five discharges at maximum
energy are still possible. (Possibly even considerably more)
Performance check of defibrillation is performed by discharging into the integrated 50-ohm
resistor.
Monitoring battery charge via the connector for power cord by the yellow LED. If the battery is
fully charged after 16 h, trickle charging ensues, the yellow LED is permanently lit up.
The monitoring function of the CardioServ records and monitors the ECG and oxygen saturation level. The cardiac-action potentials are fed to the ECG preamplifier via a 5-wire patient
cable. Selection can be made from 12 leads. The ECG curve is displayed on the LC screen
with an illuminated background. The heart rate obtained from the ECG signal is continuously
displayed on the screen.
Communication between the user and the instrument is via the keyboard and the LC screen.
These also serve to configure the default settings and functions (see Users Manual for further details).

The PCBs have the following functions:
PCB Power Supply
This PCB supplies the 16.5-V instrument power supply. 10 A can be supplied for short-term
capacitor charging. It is a primary clock-rated wide-range power supply system. It operates
from 85 .. 264 V, at 49 ... 65 Hz. It is protected by 2 fuses in the primary circuit. One on the
PCB and one in the feed line.
PCB Analog
This PCB has several functional units.
The first unit accepts the ECG signals (patient input) received via the patient cable from the
patient. In accordance with its task, it is connected to the patient by a cable. It is thus
constructed as an application component isolated from other circuit components and the
circuit reference (floating). The tasks of this circuit component are:
- amplification of ECG signals
- lead selection (lead selector)
- identification and reporting of electrode defects
- identification and reporting of patient lead connection
- digitization and serialization of ECG data
- potential separation of the application component from the remaining circuit components
(floating)
- floating component power supply
- ECG trigger
- pacing-pulse detection
There are two of these circuit components on this PCB. Once for the ECG via paddles, once
for the ECG via patient cable.
A second unit provides floating separation and the power supply for SPO2.
A further circuit component controls high-voltage generation for the Defi shock. There is a
high-voltage capacitor on this PCB. The functions are as follows :
- safety control during charging and shock release (1st path : hardware)
- controlling storage operation and energy release, independent of the CPU
- controlling the high-voltage generator
- elimination of interference in the operating elements in the Defi electrodes
- conversion of the voltage and current signals into a frequency to measure energy
- activation and control of the high-voltage transformer
- generation of the emergency cutoff signal in the event of inadmissibly high voltage
- measurement of the high voltage on the primary winding of the high-voltage transformer
227 483 02-B SA(e)-98.05

3.2 Important Servicing Note:
Replacing CardioServ PCBs
When CardioServ PCBs are replaced the technician must call up the self-test screen after
replacing the PCB. The new components are reported automatically in the software configuration. After restarting CardioServ recognizes the new components. This is important in the
case of SpO2 and Pacemaker. Further the Performance Check (see on Page 62) needs to
be accomplished.
Replacing PCB Digital
The identification numbers 0000 and 1111 are stored in the Eeprom of the PCB Digital for
CardioServ Manual and CardioServ VF, respectively.
The replacement PCB always has the identification number 0000 stored in the Eeprom for
CardioServ Manual.
If during servicing the replacement PCB Digital is inserted into a CardioServ VF, when it is
switched on the CardioServ is in the manual mode. The following combinations of keys are
required to switch the CardioServ from manual to semi-automatic operation.
1. Press F1 and F5 keys simultaneously: The function Configuration appears on the screen.
2. Press F3 and F4 keys simultaneously: The function Key Test appears on the screen.
3. Press the Analysis key.
4. Press F3 and F4 keys simultaneously.
The identification code for the CardioServ VF stored in the Eeprom of the PCB Digital is now
1111 and the CardioServ operates in the semi-automatic mode.
