1 Introduction

1.1 What’s ANASTAZJA 7500?

ANASTAZJA 7500 is a compact and integrated anesthesia transmitting system. The breathing
machine not only provides patients in operation with auto ventilation, but also monitors and
displays the patient’s various parameters. The ventilator used in the system is controlled by a
microprocessor.

The anesthetic ventilator controlled by microprocessor of ANASTAZJA 7500 includes monitor
internally, volume mode, and other functions optional. It can be used for communication with
cardiac blood vessel and monitor of breathing gas by serial interface.

Not all the optional functions available may be included in the manual. It is also possible to add
other equipment to the top or middle of this system for added functions. For more information
with respect to the existing product, please feel free to contact the local representatives.

WARNING: The user of ANASTAZJA 7500 must be professional and trained.

WARNING: ANASTAZJA 7500 is unsuitable for use in a magnetic resonance

imaging (MRI) environment.

1.1.1 Range for used

ANASTAZJA 7500 is applicable for patients of over 25 Kg with standard set and for child of over
12 Kg with cycles and CO2 monitoring device of child.

WARNING: ANASTAZJA 7500 is not to be used with infant.

2 Anesthetic System Control

2.1 Anesthetic system

CAUTION: The anesthetic system is intended to be used with the following

monitoring devices, alarm systems, and protection devices:

-- pressure measuring in accordance with 8.1 of ISO 8835-2;

-- pressure limitation device in accordance with 51.101.1 of
IEC60601-2-13;

-- exhaled volume monitor in accordance with 51.101.4 of
IEC60601-2-13;

-- breathing system integrity alarm system in accordance with

51.101.5 of IEC60601-2-13;

-- continuing pressure alarm in accordance with 51.101.6 of
IEC60601-2-13;

-- O2 monitor in accordance with ISO 9918.

WARNING: To avoid explosion hazards, flammable anesthetic agents such as

ether and cyclopropane shall not be used in this anesthetic
workstation. Only anesthetic agents which comply with the
requirements for non-flammable anesthetic agents as specified in
this manual.

Halothane, desflurane, sevoflurane, enflurane,and isoflurane have
been found to be non-flammable agents.

WARNING: Independent means of ventilation (e.g. a self-inflating manually

powered resuscitator with mask) should be available whenever the
anesthetic system is in use.

WARNING: Do not use antistatic or electrically-conductive breathing tubes and

mask.

WARNING: Leakage and douse of liquid, such as anesthetic agent, bring on

dangerous states or malfunctions inside device.

Operating method:

 Move the cursor to the item where the operation is wanted

 Press the knob

 One of the following four situations may appear:

 The background color of cursor may become into the contrast color, which

implies that the content in the frame can change with the rotation of the knob.

 Pull down menu or dialogue box may appear on the screen, or the original menu

is replaced by the new menu.

 Save setup.

2.4.5 Display Screen

The display of the ventilator is a color TFT, which can display the monitoring and setting
parameters, waveforms, alarm information as well as displayed on the screen. See Figure 2-9.

The screen has three areas: information area (1), monitoring area (2), and parameter setup
area (3).

Figure 2-9 Display Screen

2.4.5.1 Information area

Information area lies on the top part of the screen, which is used to display the current status of
the ventilator and the patient. The information area contains following components:

Figure 2-10 Information area

1 Alarm bell

When alarm appears, the color of alarm bell accords with the background color of the
upper prior alarm message; press alarm silence key, “X” dashed line appears on the alarm
bell, and 110 seconds counts down. More details refer to section 8.1.

2 Alarm messages

Technical alarm and functional alarm supplied by the system, and not more than two alarm
messages displayed on the top of the screen. More details refer to section 8.2.

3 Power supply

Two kinds of power supply: AC power external and internal battery.

4 Ventilation mode

Five ventilation modes: VCV mode, Pressure mode, SIMV mode, Manual mode, and
Standby mode.

Turn and press the knob to setup ventilation mode required, and press again to save it.

2.4.5.2 Monitoring area

Monitoring area has two parts: Patient parameter and waveform.

Patient parameter is fixedly displayed in the left side of the monitoring area. It includes seven
parameters:

Tidal volume MV: Minute volume

VT:

f: Respiratory frequency P

P

: Pressure at the end of

plat

: Peak value of airway pressure

FiO2: Oxygen concentration

inspiratory pause time

C: compliance

Waveform is displayed in the right side of the monitoring area. It has four types:

Flow-t waveform, V-t waveform, Paw-V loop and V-FLOW loop.

More details refer to section 3.5.

2.4.5.3 Parameter setup area

Parameter setup area lies on the bottom part of the screen. It includes:

VT: Tidal volume f: Breaths per minute

I:E: Inspiration to expiration time TP: Inspiratory pause time

Interface

Use oxygen sampling line to connect O2 sensor with O2 sensor
interface.

Oxygen concentration value measured by O2 sensor is transmitted
to the ventilator through O2 sensor interface.

If no O2 sensor in the breathing system, the alarm message “No O2
sensor!” will be shown in the display screen.

Connect sampling parallel line to P&V interface, the other end to
probe.

It provides basis for monitoring and troubleshooting that the real
time airway pressure is transmitted to the ventilator.

Parameter monitored such as VT and MV, are calculated by
ventilator basing on the flow via the probe.

CAUTION Ensure sampling line and probe connect

right, avoid liquid entering and leakage.

—— Probe of sampling and sampling parallel line

Flow of breathing cycle is measured by means of pressure
difference.

Avoid water entering into the probe and sampling parallel line in the
process of operating, otherwise parameter monitored will be
affected.

Ensure airtightness of sampling system, if sampling device is aging,

please replace it.

Sterilization: cleaning it with sterilizing agent, then swing it

mechanically. The formation and preparation of the agent must be
done in accordance with the direction given by the manufacturer.
