Operation

1.3. Device operation.

DEFIGARD 5000 is a monitor/defibrillator designed for in-hospital use. It is started up by keeping the On/Off key on the upper keypad pressed down for two seconds or more.

Power supply:

The device is powered by the mains, a battery (lithium ion battery only) or an external 9 - 48 VDC power supply. It has a fixed battery in the lower slot, which can be charged from the mains or the external VDC power supply. The capacity of the battery is sufficient for:

- 70 shocks at the maximum energy or

- 2 hours of monitor operation.

A second removable battery (optional) may be inserted in the upper slot to double the life.

Defibrillation:

DEFIGARD 5000 is a defibrillator that uses pulse biphasic waveforms - Multipulse Biowave®.

The device offers two operating modes, the semiautomatic mode, called SAD, and the manual mode. These two operating modes depend on the type of defibrillation cartridge inserted. There are three types of cartridge

- adhesive electrode cartridge, internal electrode cartridge and handheld paddle electrode cartridge. A window on the screen indicates the defibrillator settings.

Possibilities offered by the defibrillator:

- Manual defibrillation with adhesive electrodes For manual defibrillation with adhesive electrodes, you need to use the cartridge for adhesive electrodes. The charge and energy selection buttons are located on the side keypad, whilst the shock button is located on the upper keypad.

- Semiautomatic defibrillation with adhesive electrodes The same cartridge is used with adhesive electrodes. The device must offer the semiautomatic function. Adhesive electrodes are available for children and adults. The device recognises the type of electrode applied and selects the defibrillation energy levels accordingly. The control buttons for analysing and shock delivery are located on the upper keypad.

- Internal manual defibrillation (optional) Use the cartridge that offers the facility to use the internal defibrillation paddles. The charge and energy selection buttons are on the side keypad. The shock button is located on the upper keypad.

- Manual defibrillation with handheld electrodes (optional) Use the handheld electrode cartridge. The charge/shock button and the energy selection button can be found on the electrodes.

Semiautomatic mode: In the SAD mode, the user takes action on the basis of the messages sent by the system (in accordance with AHA/ERC protocols). At any time (except during CPR), if an electrode fault is detected, the AHA/ERC protocol is stopped. It is resumed when the fault disappears. During the analysis (which is set off by pressing the Analyse key), if a loose contact is detected, the analysis is interrupted throughout the duration of the fault. It is automatically resumed when the fault disappears. After an initial analysis, if the analysed ECG signal is too weak, a message asks the user to apply CPR (cardiac pulmonary resuscitation) for one minute. The display lasts during that time, when pressing the Analyse key starts off the analysis cycle. After an initial analysis, if there is noise in the ECG signal, a message is displayed for one minute to ask the user to apply CPR (cardiopulmonary resuscitation). The display lasts during that time, when pressing the Analyse key starts off the analysis cycle.

0-48-0065 Page 1-5 June 2005

Operation

The energy is selected automatically by the system in accordance with the AHA/ERC protocol. An energy sequence is available:

Shock 1 : Energy selected 130 J Shock 2 : Energy selected 130 J Shock 3 : Energy selected 150 J

.................................................................

Shock N : Energy selected 150 J

If VF is recognised during the analysis, the software automatically starts charging the capacitor with the appropriate energy. If the charge lasts too long, it is discharged internally. The shock is delivered manually. Pressing a key automatically delivers the energy stored in the capacitor. The system receives the values of the delivered energy, the patient current and the patient impedance. If the shock is not given within a given time or if the system detects a heart rhythm that does not call for a shock, the energy is discharged internally.

Manual mode: The manual mode is accessible directly when the device is turned on or when the Physician key is pressed while in the semiautomatic mode. It unlocks the use of the defibrillator, allowing the operator to control the device entirely. In the manual mode, the user can defibrillate patients synchronously with an ECG.

Pacemaker (optional)

For the pacemaker function, you need to use the cartridge for adhesive electrodes. The keys for starting up the pacemaker and setting the pacing frequency or current and the fixed, demand or overdrive mode are located on the side keypad. If the pacemaker is operating, the defibrillation function is disabled.

ECG function

This module is always powered and the ECG signal can be collected with 3, 4 or 10-lead cable. Depending on the configuration, the device can display up to 12 leads at the same time. Four amplitude values may be set (0.25, 0.5, 1 and 2 cm/mV), as may two signal scanning speeds (25 and 50 mm/s). The QRS frequency is also displayed.

0-48-0065 Page 1-7 June 2005

Operation

SPO2 function (optional)

The window of this function is only displayed on the screen when the SPO2 connector is detected by the device. The window displays the SPO2 curve and the saturation rate. When the screen displays the 12 leads of the ECG, the SPO2 curves disappears, but the saturation rate remains displayed.

NIBP function (optional)

The NIBP may be set to Adult or Infant. For each configuration, you can take manual, continuous or cyclical measurements. The Sys, Dia and MAP values are displayed on the screen.

Memory function

The ECG curve and the trends are saved in a compact flash memory in the device.

Data transmission function

- A connection for GSM or standard modems is provided for transmitting the 12-lead ECG

- A USB connector is provided for retrieving data from the device

- An Ethernet link for upgrading software

All the connectors are located at the rear of the device.

Recorder function (optional)

The recorder can print ECG, SPO2 or trend curves.

Testing and maintenance

2. Testing and maintenance

This section describes the test and maintenance procedures recommended with DEFIGARD 5000.

2.1. Functional testing

The device runs an automatic test every time is switched on. The test lasts less than 5 seconds and consists in checking all the hardware functions. If a blocking error is found, an error message is displayed on the screen and a sound alarm is emitted till the device is switched off by the operator (by pressing the Off key). The device is blocked and goes off automatically after five minutes.

The device can run a periodic automatic test at a configurable frequency. That automatic test may be daily, weekly or user-defined by indicating the number of days between two tests (1 to 30 days). A key for immediately starting up the test is available as well. During the self test, all the hardware functions and the battery charge status are tested. No information is displayed on the screen during the test. The test result is saved and can be retrieved subsequently. The last 30 tests are saved. If the tests do not show any error, the system goes off automatically. If, on the other hand, a serious error is found, a sound alarm is emitted for 10 seconds every 2 minutes till the device is switched on again. At that time, the error is displayed on the screen. The device is blocked. A selection is available to restart all the tests. If the tests do not show any error, the system starts up nominal operation. If, on the other hand, a blocking error is found, the error is displayed on the screen and a sound alarm is emitted till the device is switched off by the operator (by pressing Off). The device is blocked.

2.2. Cleaning and disinfecting

Caution: Switch the device off before cleaning it. Remove the cell

The device or electrodes may never be cleaned with substances such as ether, acetone, esters, aromatic chemicals etc. Never use phenol-based cleaners or cleaners containing peroxide derivatives to disinfect the surfaces of the housing of the device.

· Dispose of all single-use electrodes immediately after use in order to eliminate the risk of accidental reuse (disposal with hospital waste).

· Before cleaning the electrode cables of sensors, disconnect them from the device. For cleaning and disinfecting, wipe the cables with a gauze cloth moistened with cleaner or disinfectant. Never immerse the connectors in liquid. The cleaning solution used may be any cleaning or disinfecting solution that is commonly used in hospitals.

· Proceed likewise with the device housing, with a cloth moistened with cleaner or disinfectant. No liquid may be allowed to penetrate into the device during the operation.

before you start cleaning the device in order to eliminate the risk of the device starting up accidentally. Also disconnect the defibrillation electrodes of the device before cleaning.
