1 Introduction

1.1What’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.

1.1.1Range 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

2.1Anesthetic 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.

		Mains switch key	Press the key and hold on for 2 second, you
			can start or shut off ventilator.
		Alarm silence key	Press the key, alarm mutes for 110 seconds.
			Press the key, change original ventilation
		Manual mode key	mode to manual mode; Press again, back to
			the original ventilation mode.
			Press the key, a “Menu” window appeared on
		Menu key	the display screen, more details refer to
			section 2.5.
2.4.3	Indicators
		Running Indicator	The indicator brightly as ventilator operating.
		AC Indicator	The indicator brightly as AC power effectively;
			The indicator dark as AC power failure.

2.4.4Knob

The user may use the rotary knob to select the menu item and modify the setup. It can be rotated clockwise or counter-clockwise and pressed like other buttons. The user may use the knob to realize the operations on the screen and in the system menu and parameter menu.

The rectangular mark on the screen that moves with the rotation of the knob is called “cursor”. Operation can be performed at any position at which the cursor can stay.

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 Anesthetic System Control

2.4.5Display 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

2.4.5.1Information 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

1Alarm 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.

2Alarm 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.

3Power supply

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

4Ventilation 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.

2.4.5.2Monitoring 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:

VT:	Tidal volume	MV:	Minute volume
f:	Respiratory frequency	Ppeak:	Peak value of airway pressure
Pplat:	Pressure at the end	of 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.

2.4.5.3Parameter 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
Plimit:	Maximum airway pressure limit	Vsens:	Triggering flow sensitivity
	setting

			Don’t block exhaust port.
			It is only a outlet of driven gas. Safety valve inside exhaust port may
	4	Exhaust Port	be used	to limit	maximum of airway pressure. When airway
			pressure exceeding the maximum, the safety valve will open and
			exhaust for protecting airway of patient.
			The maximum airway pressure is 6 kPa.
			Size: male 16 mm taper
			Use thread-tube to connect driven gas outlet with driven gas inlet of
			bellows.
	5	Driven Gas Outlet	Inspiratory phase: gas from ventilator drives bellows to make fresh
			gas enter into the airway;
			Expiratory phase: return gas from the airway drives bellows to make
			gas from ventilator exhaust through exhaust port.
