the safety, the special requirements for the use Siaretron lung ventilator and
the relative safety regulations.
•In order to understand how the Siaretron lung ventilator works and how
to use it correctly to ensure patient and user safety, the
recommendations and instructions contained in this manual must be
read with care and understood.
•The User's Manual is an integral part of this manual; the technician
must retain a copy and understand the contents before performing
the operations described in the Service Manual.
•The lung ventilator must only be used for the purposes specified herein
and the safety of the equipment is therefore only guaranteed if it is used
in accordance with the instructions given in the User’s Manual.
•The materials used were carefully selected during the design stage after
specific checks, tests and comparative trials: these materials are also
constantly inspected during the production cycle to achieve the best
results in terms of reliability and safety for the patient and the operator.
Any part of circuit must therefore only be replaced with original spare
parts supplied or checked by SIARE.
•The lung ventilator must only be used by qualified personnel and only in
equipped and dedicated rooms, according to the regulations in force in
the country where the equipment is installed.
•To ensure correct technical assistance and avoid possible physical
damage to the patient, the maintenance schedule foreseen in the
User’s Manual must be respected; qualified personnel must only carry
out maintenance of the lung ventilator or authorised modifications to the
equipment. The user of this product is solely responsible for any
operating defect caused by improper use or interventions carried out by
third parties other than specialised SIARE personnel.
•For any repairs to lung ventilator (due to malfunctioning, defects or
failures), the user must contact SIARE or the authorised local Technical
Service Centre; it is advisable to specify the data on the identification
label (model, serial number, ……) when requesting intervention.
•SIARE recommends establishing a maintenance and service contract
with SIARE or the local authorised service dealer in order to guarantee
the scheduled maintenance required to operate the lung ventilator in a
safe and correct manner.
•To prevent the risk of fire, keep the lung ventilator and/or the oxygen
tubes of the equipment away from matches, lit cigarettes and
inflammable material, such as anaesthetic gases and/or sources of
heat.
•Do not connect the lung ventilator to the patient by flexible connectors,
and antistatic or conductive tubes to prevent patient burnings during the

use of high frequency surgical equipment, specially dangerous with
antistatic tubes. The use of flexible connectors, antistatic or conductive
tube is never permitted with Siaretron lung ventilator.
•Do not use worn and consumed tubes or tubes contaminated by
flammable substances like grease or oil to deliver oxygen; (fabrics, oil
and other fuels can easy ignite and they intensively burn in air with high
concentration of oxygen.
•In the event of fire or an unpleasant smell (e.g. a smell of burning), the
lung ventilator should immediately be disconnected from the electrical
power supply and from the battery (if fitted).
•When coming into contact with any component of the lung ventilator, the
hospital procedures for the handling of infected material should always
be respected.
•SIARE is aware that cleaning, sterilisation and disinfection procedures
vary considerably from one health structure to another. SIARE cannot
be held responsible for the efficacy of the cleaning and sterilisation
procedures, nor for the other procedures carried out while the patient is
being treated. As regards cleaning, sterilisation and disinfection of the
product components, it is therefore recommended that the regulations
currently in force in the country where the equipment is installed be
taken into consideration.
•The Siaretron lung ventilator was not designed as a total monitoring
device: some conditions of danger for the patients treated with vital
support equipment will not trigger any alarm.
•Before using the lung ventilator or any connected component, carefully
check that the equipment is functioning correctly; when needed, the
auto-diagnostic test must be performed as described in the User’s
Manual.
•Do not use pointed instruments, such as pencils, screwdrivers or the
like to make selections or settings as they could damage the surface
of the LCD panel.
•Check the lung ventilator periodically as described in the relative
“Maintenance” chapter and do not use it if it is faulty or malfunctioning.
Replace any broken, missing, obviously worn, deformed or
contaminated parts immediately, with spare parts supplied by SIARE.
•Do not connect external devices NOT manufactured or NOT authorized
by SIARE to the equipment (example: scavenging systems, patient
simulators, etc…..), and not described in the present service manual: in
case of need contact SIARE.
•The correct functioning of the lung ventilator can be impaired if original
SIARE spare parts and accessories are not used; the use of other
accessories is however allowed only if formally authorised by SIARE
in accordance with current safety regulations.

•SIARE assumes all foreseen legal liability if the lung ventilator is used
and periodically maintained according to the instructions contained in
this manual: the Technical Assistance Report, drawn up and signed by
the authorised SIARE technician, is proof of the completion of the
scheduled maintenance.
•Notwithstanding the Siaretron lung ventilator is equipped with a safety
valve which allows to the patient to breathe spontaneously the ambient
air even in case of gas supply failure, the auxiliary ventilation system
must be always promptly available; such a component is part of SIARE
ENGINEERING INTERNATIONAL GROUP s.r.l. products range.

by SIARE, must know the full content of this manual, before carrying out
the operations described below.
The SIARE authorised technician avails of suitable tools and spare parts
and is trained to work in compliance with product safety.
This Service Manual describes the Siaretron 4000 lung ventilator equipped with a turbine
and with a 12” TFT display (referred to from now on as: lung ventilator) along with its
principle of operation, by means of manufacturing, wiring and pneumatic diagrams. The
specialist SIARE staff or qualified technical staff, formally authorised by SIARE, must
know the full content, before carrying out the operations described below.
The SIARE authorised technician avails of suitable tools and spare parts and is trained to
work in compliance with product safety.
The correct and safe use for the patient and the operator of the equipment requires
knowledge of the recommendations and instructions outlined in this manual and the user
manual.
SIARE declines all liability for technical interventions carried out on the
equipment without formal authorisation from SIARE.
The User Manual is an integral part of this manual; the technician must
have a copy and know its content, before carrying out the operations
described in the Service Manual.
1.1 Intended use
The Siaretron 4000 system delivers controlled or spontaneous ventilations with a re-adjustable
level of end expiration positive pressure (PEEP), of the trigger sensitivity and oxygen
concentration.

Adult, paediatric and neonatal ventilation are available, thanks to an adjustable minimum Tidal
Volume from 2 ml to 3000 ml.
After the switching-on of the lung ventilator it is possible to choice the patient type (adult,
paediatric and neonatal) setting the relevant default parameters.

The lung ventilator is equipped with a flow and pressure trigger, also it includes the most
modern ventilation modes: volume controlled ventilation modalities VC/VAC, VC/VAC-
BABY, pressure controlled ventilation modalities APCV (BILEVEL ST), APCV-TV, SIMV by
Volume and by Pressure, Pressure supported modalities PSV (BILEVEL S), PSV-TV,
CPAP/PSV, SIGH, Non Invasive Ventilation (NIV APCV –NIV PSV), Drug Nebulizer and
Manual Ventilation (MAN).
In spontaneous ventilation mode, it ensures inspiratory flow up to 190 l/min, both with control
and support pressure.
The battery, in perfect conditions and fully charged, allows the lung ventilator to operate for at
least 90 minutes (without humidifier), allowing to power the lung ventilator in case of transport
within hospital facilities. It is possible to reach an autonomy of about 3 hours by the aid of an
auxiliary external battery (or battery pack).
This manual features the Siaretron 4000 ventilation system instructions for
use and servicing.
SIARE recommends careful reading of this manual and the relative
instructions before starting or servicing the lung ventilator.
For those who already have a basic knowledge on ventilators operation
and lung ventilation in general, the user interface is intuitive and a simple
consultation of this manual should be enough to assure an optimal use of
Siaretron 4000 ICU lung ventilator.
1.2 Main features
The Siaretron 4000 lung ventilator is composed of two main blocks: the trolley and the
ventilator block.
In turn, the lung ventilator block is divided in two parts: the upper part that includes a 12” TFT
colour monitor, the board for the elaboration of all data and information (CPU) that supervises
the operation and display of patient parameters.
To manage the pneumatic part and the turbine, the CPU board uses serial transmission
system by bus, type Controller Area Network (also known as CAN BUS) that allows it to check
and communicate with the electronic boards peripherals.
The CAN communication system was expressly designed to operate without any problem also
in environments highly disturbed by the presence of electromagnetic waves. The EMC
immunity level is further increased by using twisted pair type connection cables. The lower
part of the lung ventilator block includes the pneumatic control and all the fittings or
connections, both electrical and pneumatic, to the outside.
In this area are also mounted the back-up batteries for use in case of power supply absence
and the board for battery charge management.
The Siaretron 4000 foresees the possibility to upgrade the software for implementing
advanced ventilation modalities and functionalities.
The lung ventilator block can be used as a stand-alone part being separable from the trolley,
by positioning it on a flat surface.
1.3 Correct operation
For proper and full lung ventilator operation, you should make sure that:
•the lung ventilator is connected to the air and oxygen inlets of the cylinders or of the
medical gas distribution system; the compressed air can also be provided by the medical
air compressor (optional);
•the lung ventilator is properly connected to the patient circuit;
•the lung ventilator is connected to a mains socket that has the same voltage as the one
specified on the machine identification plate;

•all accessories and devices, necessary for lung ventilator operation, are properly
connected.
The connection with main power supply, as well as connections with medical gas
distribution system must be effected according to the indications contained in the
present user’s manual (see chapter 2).
The Siaretron 4000 lung ventilator doesn’t require any high pressure air supply as
it is equipped with an internal turbine.
The lung ventilator incorporate a series of sensors for continuous patient monitoring, the most
important of which are:
•the flow sensors on the expiratory / inspiratory lines, are used to measure the expiratory /
inspiratory volumes of the patient;
•the pressure sensors, used to control the pressure of the airways or of the medical gases;
•the oxygen sensor, used to measure the concentration of oxygen in the gas inspired by
the patient.
Before using the lung ventilator, the clinician should check the
operation of all these sensors in order to avoid any incorrect
assessments of patient's condition.
WARNING !!
Before using the lung ventilator on a patient it is necessary to perform
a series of preliminary checking to verify the correct operation of the
equipment.
The preliminary checking has the aim to verify the correct connections
and functionalities of the lung ventilator and all its parts.

For its employ the Siaretron 4000 lung ventilator has been designed and
made to guarantee full quality of the product and its components, in
order to ensure the maximum reliability of the lung ventilator for the
patient and user safety.
To ensure the best performance of the lung ventilator periodic
maintenance of the unit by qualified technical personnel is
recommended. For further information, contact SIARE Engineering
