3 ntended Use
Fabius® is an inhalation anesthesia machine with continuous fresh-gas flow for patients with
a body weight of 5 kg and over.
Fabius is intended for use in operating theatres and induction and recovery rooms. It can be
used with O2, N2O, and (optional) AIR supplied from a central supply system and/or from
medical gas cylinders.
Fabius is fitted with the circle absorption system "Circle System 9/Fabius". This circle
absorption system is a partial rebreathing system which provides fresh-gas decoupling,
PEEP (positive end-expiratory pressure), and pressure limitation.
Fabius offers the following ventilation modes:
−IPPV (Intermittent Positive Pressure Ventilation)
−MAN (Manual Ventilation)
−SPONT (Spontaneous reathing)
Fabius is equipped with an electrically driven and electronically controlled ventilator. The
control unit (control box) monitors the airway pressure (Paw), the flow, and the O2
concentration.
The anesthetic vaporizer "Vapor 19.n®" enriches the fresh gas with anesthetics.

3.1 Safety Features
Fabius includes the following safety features:
−monitoring of airway pressure (Paw), flow (V), and fraction of inspired O2 (FiO2)
−built-in O2 shortage alarm and N2O cut-off
−built-in sensitive oxygen ratio controller (S-ORC) (a control device which ensures a
minimum O2 concentration of 21 vol.% in the respiratory air)
Risk of explosion in the presence of flammable anesthetics such as
ether or cyclopropane!
Do not use the machine in the presence of flammable anesthetics.
Risk of nfection! To avoid infections, clean and disinfect Fabius and
its components/accessories according to approved hospital
procedures before servicing or shipping for repair.
Risk of personal injury! Excessive CO2 and/or anesthetic
concentrations could lead to a patient’s injury.
Use CO2 and anesthetic monitors.
Risk of burns if antistatic or electrically conductive breathing tubes
are used in combination with high-frequency surgery equipment.
Do not use antistatic or electrically conductive breathing tubes in
combination with high-frequency surgery equipment.
Risk of malfunction in nuclear spintomography environment!
Do not use the machine in conjunction with nuclear spintomography
(MRT, NMR, or NM ).
Risk of malfunction! Radio communication devices may cause
malfunction in electrical medical devices.
Do not use wireless or cellular phones within 10 meters of electrical
medical devices.

4.2 General nformation about Cleaning/Disinfection
Risk of damage to materials! Disinfectants based on phenols,
halogen-releasing compounds, strong organic acids, O2-releasing
compounds can damage materials. Do not use disinfectants based on
phenols, halogen-releasing compounds, strong organic acids,
O2-releasing compounds.
Risk of damage to materials! When cleaning/disinfecting the following
components in a washing/disinfection machine use only detergents.

page 16).

5330.200 Fabius 06/98 General Page 16
For internal use only. Copyright reserved. G K5330200A01.fm 24.01.02
5 Tests of Readiness for Operation
• efore starting the tests, make sure the machine is completely re-assembled, the CO2
absorbers are (re-)filled, and Fabius is connected to the central supply system and/or to
medical gas cylinders.
• Calibrate the flow sensor.
• Calibrate the O2 sensor.
5.1 Testing the Medical Gas Connections
• Make sure all hoses to the central supply system and/or to the medical gas cylinders are
connected securely.
• Make sure all hoses to the central supply system and/or to the medical gas cylinders are
free from leaks.
5.2 Testing the Flowmeters
• Adjust the O2 flow control valve to 9 L/min.
The float of the O2 flowmeter should indicate 9 L/min.
• Adjust the O2 flow control valve to 1.5 L/min.
• Adjust the N2O flow control valve to maximum.
The float of the N2O flowmeter should be between 3 L/min and 5 L/min.
• Disconnect the O2 supply connector from the terminal unit or, if Fabius is connected to
an O2 cylinder, close the O2 cylinder valve.
The O2 shortage alarm should sound. The float of the N2O flowmeter should descend to
0L/min.
• Connect the O2 supply connector to the terminal unit or, if Fabius is connected to an O2
cylinder, open the O2 cylinder valve.
The N2O flow should continue.
Perform tests of readiness for operation after each care procedure.

5330.200 Fabius 06/98 General Page 17
For internal use only. Copyright reserved. G K5330200A01.fm 24.01.02
• Adjust the AIR flow control valve to 14 L/min.
AIR should flow.
• Close all flow control valves.
5.3 Testing the Gas Type
•Switch on Fabius.
• Select the IPPV mode.
• Disconnect the fresh-gas hose from the fresh-gas output port.
• Adjust the O2 flow control valve to 3 L/min (leave the other flow control valves closed).
• Unscrew the O2 sensor assembly from its mount.
• Place the O2 sensor assembly in the fresh-gas flow near the fresh-gas output port.
The fraction of inspired O2 (FiO2) should be about 100 vol.% (the FiO2 is displayed on the
control box).
• Adjust the N2O flow control valve to 3 L/min.
The fraction of inspired O2 (FiO2) should decrease to about 100 vol.% (the FiO2 is displayed
on the control box).
• Close the O2 flow control valve.
• Close the N2O flow control valve.
•Screw the O
2 sensor assembly onto the inspiratory valve.
• Connect the fresh-gas hose to the fresh-gas output port.
The O2 shortage alarm is ready to operate again as soon as the operating
pressure exceeds 2.7 bar for 20 seconds and no O2 is used during this
period.
