tion to assure that you get the most from your equipment.

CardioSys is a class I system.

☞

Before connecting the device to the power line, check that the voltage and frequency ratings of

Caution

the power line are the same as those indicated on the system’s nameplate. If this is not the case, do not connect the system to the power line.

Do not use extension cables with multiple

Warnin

power outlets to connect the system to the power line.

Before putting the system into operation visually inspect all connecting cables for signs of

Danger

damage. Damaged cables and connectors must be replaced immediately.

When disconnecting the system from the power line, remove the plug from the wall outlet first.

Danger

Then you may disconnect the power cord from the device. If you do not observe this sequence, there is a risk of coming into contact with line voltage by inserting metal objects, such as the pins of electrode leads, into the sockets of the power cord by mistake.

10 CardioSys V4.1 227 498 02-A

Introduction to CardioSys

Caution

Warnin

CardioSys can be operated on an uninterruptible power supply (UPS). The UPS should not be disconnected from the power line for prolonged periods of time to prevent deep discharging of the battery. For this reason, switch the CardioSys system off and on with the system’s own power switch and do not use the switch of the UPS or the main power switch of the office. As a general rule, the UPS must first be connected to the power line and switched on; then you may switch on CardioSys. Do not switch on the CardioSys system during a power outage. Only the CardioSys system may be connected to the UPS. The UPS must be installed within the medically used room, but outside the patient environment. Observe the information given in the UPS user manual.

The power socket of the CardioSys system cart is reserved for a defibrillator for recharging of the defibrillator battery (max. power 30 VA).

All devices of a system must be connected to the same power supply circuit. Devices which are not connected to the same circuit must be electrically isolated when operated (electrically isolated RS232 interface).

Set up the device in a location which affords sufficient ventilation. The ventilation openings

Caution

of the device must not be obstructed. The ambient conditions specified in the “Technical Specifications” section must be ensured at all times.

The system should be set up to provide the opera-

☞

tor an unobstructed view of the control panel.

Devices intended for emergency application must not be stored or transported at tempera-

Danger

tures which cause moisture condensation at the application site. Wait until all moisture condensation has evaporated before using the device.

If the system is used as an emergency device, a

Warnin

second ECG recorder must be available.

The device is not intended for intracardiac

Warnin

application.

The device is not suitable for operation in areas

Warnin

where an explosion hazard may occur. Explosion hazards may be caused by the use of flammable anesthetics, skin-cleansing agents and disinfectants. Great care must be exercised when the monitor is used in an oxygen-enriched atmosphere. The atmosphere is considered to be oxygen-enriched when the room air contains more than 25% of oxygen or nitrous oxide.

227 498 02-A CardioSys V4.1 11

Introduction to CardioSys

Warnin

The patient signal input is labelled with the

symbol, indicating that it is protected against damage resulting from defibrillation and electrocautery. Nevertheless extreme care must be taken when devices which are directly connected to the patient remain applied during defibrillation. The distance between ECG electrodes and defibrillation paddles should be at least 6 in./15 cm. If in doubt, disconnect the patient cable from the device while applying the defibrillation pulse.

Magnetic and electrical fields are capable of interfering with the proper performance of the device. For this reason do not operate the system in the vicinity of equipment emitting strong electromagnetic radiation (X-ray equipment, diathermy systems or MRI devices).

Only use the original Marquette Hellige patient cable. Do not connect other signal sources to the cable.

With all peripheral devices connected, CardioSys represents a medical system. It fulfills the requirements of the system standard IEC 60601-1-1. The entire system may be operated in the patient environment.

Warnin

Danger

Warnin

If the system cart is installed in the patient environment, only the special printer modified by Marquette Hellige and equipped with an additional protective earth connection (potential equalization) may be operated. Observe the assembly instructions supplied with the printers.

For stress-test examinations, a defibrillator and a pacemaker, regularly checked for proper functioning, must be readily accessible.

Extreme care must be exercised when using medical electrical equipment. Many parts of the man/machine circuit are conductive, such as the patient, connectors, electrodes, transducers. It is very important that these conductive parts do not come into contact with other grounded, conductive parts when connected to the isolated patient input of the device. Such contact would bridge the patient’s isolation and cancel the protection provided by the isolated input. In particular, there must be no contact of the neutral electrode and ground.

12 CardioSys V4.1 227 498 02-A

Introduction to CardioSys

Warnin

Danger

Devices may only be interconnected with each other or to parts of systems when it has been made certain that there is no danger to the patient, the operators, or the environment as a result. In those instances where there is any element of doubt concerning the safety of connected devices, the user must contact the manufacturers concerned or other informed experts as to whether there is any possible danger to the patient, the operator, or the environment as a result of the proposed combination of devices. Standards IEC 60601-1-1/ EN 60601-1-1 must be complied with in all cases.

Liquids must not be allowed to enter the devices. Devices into which liquids have penetrated must be checked by a service technician before being used again.

Medical technical equipment such as the

☞

CardioSys system must only be used by persons who have sufficient knowledge, who have received adequate training in the use of such equipment and who are capable of applying it properly.

Before using the system, the operator is obliged

Warnin

to verify that it is in correct working order and operating condition.

The operator must be familiar with the operation of the system.

Caution

Verify the performance of the system once a month.

Caution

Dispose of the packaging material, observing

Warnin

the applicable waste control regulations and keeping it out of children’s reach.

Chemicals required for the application or maintenance of the devices must under all

General Information on System Operation

2.1 Operating the Program with a

Mouse

All operating steps required to run the program can be performed with a mouse. The screen layout permits swift program operation, and text entries via the keyboard have been reduced to a minimum. The system allows you to create libraries for various situations, which you can copy from the list to the respective text boxes in a dialog window, using the mouse.

If you are already familiar with the functions and handling of a PC mouse, you can skip this paragraph.

Some General Remarks on the PC Mouse

When entering text via the keyboard, use the

☞

key to move from text box to text box. This will save time as your hands can stay on the keyboard all the time.

Figure 2-1. Mouse buttons

20 CardioSys V4.1 227 498 02-A

An arrow or mouse pointer appears on all screens. This mouse pointer moves around on the screen as you move the mouse on the table. Sliding the mouse to the right, for instance, shifts the pointer to the right.

The program can be used with a two or a three-button mouse (Figure 2-1). The buttons are operated with the index finger and the middle finger. The left button (index finger) controls almost all functions, while the right button (middle finger) is seldom used.

The icons displayed on the monitor screen resemble the operating controls on a conventional ECG recorder (Figure 2-2).

To select a function you place the mouse pointer on the respective icon and press the left mouse button. You will see that the key on the screen is “pressed” at the same time.

Pressing a mouse button is also called “clicking”. When, later

on in this manual, you are asked to “double-click” this means that you should press the left mouse button twice in rapid succession.

On many screens you will see windows offering various selections (Figure 2-3).

To select an option, move the mouse pointer to the item and press the left mouse button. This selects the item, and the window disappears.

When a list of selections is too long to fit in the window, the window has a scroll bar at its right edge. Clicking the arrow at the upper end of the scroll bar moves the list down one by one (1, Figure 2-3), clicking the lower arrow moves the list up (2, Figure 2-3).

A so-called scroll box between the two arrows allows you to move quickly through the list by clicking the scroll box, holding the mouse button depressed, and dragging the box up or down (3, Figure 2-3).
