VI User manual, DU3104101
•To prevent the risk of fire, keep the lung ventilator and/or the oxygen tubes
away from matches, lit cigarettes and inflammab
le 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, especially
dangerous with antistatic
tubes. The use of flexible connectors, antistatic or conductive tube is never
permitted with 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 easily 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 th
e 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 lung ventilator is installed be taken into consideration.
•The lung ventilato
r 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 lung ventilator is functioning correctly; when needed, the preliminary
tests must be performed as described in the present 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, def
ormed or contaminated
parts immediately, with spare parts supplied by SIARE.
•Do not connect external devices NOT manufactured or NOT authorized by
SIARE to the lung ventilator (example: scavenging systems, patient
simulators, etc…..), and not described in the present user’s manual: in case
of need contact SIARE.

VII
•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 authori
sed 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.
•

1 INTRODUCTION
SIARE Engineering International Group s.r.l. is glad to introduce this new product, result of
40 years of experience and investment in technological innovation that we are
implementing in recent years.
SIARE Engineering International Group s.r.l. has focused heavily on innovation of
materials, ergonomics and ease of use of its equipment. All routine operations have been
simplified and the operational procedures are “foolproof”, in this way there is no margin for
the user to make incorrect or inadequate manoeuvres.
The new Aria 104 lung ventilator is very different from all the previous versions and it has
been conceived for the using in Intensive Care, Emergency and Transport. Even the
maintenance procedures have been simplified and the parts subject to wear or deterioration
have substantially decreased.
1.1 Intended use
The Aria 104 is a lung ventilator equipped with an innovative pneumatic system including a
turbine with differential cooler which grant a longer duration and a higher precision in the
delivery of gas mixture.
The Aria 104 can be used on Adult, Paediatric and Neonatal patients; it has been
conceived for the using in emergency, transport, intensive care and for hospital patients
affected by chronic respiratory failure (CRF). Thanks to its versatility and a lot of new
functions, the Aria 104 can be used on patients since the first hospital recovery and for the
eventual sharpening of the pathology up to join a stable condition of the patient itself.
The Aria 104 includes new advanced functionalities that help you manage the operating
modes and the various patient ventilation functions; the keyboard and the encoder knob
simplify the settings and the operations significantly.
The present manual explains how to use the Aria 104 lung ventilator
system and how performing some simple maintenance procedures.
SIARE recommends to read carefully the present manual and its relevant
instructions before using the ventilator or proceeding to maintenance.
WARNING !!
Please read the recommendations and the instructions herein in order to
ensure a correct and safe use of Aria 104 both for the clinician and for the
patient.
The Aria 104 must be used only for the purposes mentioned below and, in
the manner, described herein, therefore the clinician must thoroughly follow
these instructions for use.

1.3.2 Electronics and driving
The electronic of the lung ventilator is developed on a single main board; this board handles
all the information received by the connected devices (the graphic interface settings,
sensors, turbine and monitor interface) and consequently set the ventilation.
The lung ventilator is equipped with a battery charger board which handle the charging of
the internal Ni-Mh battery and with an internal power supply module (feeder) which takes
care of the alarms relevant to the main power supply absence and/or discharged battery.
1.3.3 Pneumatics
The pneumatic part of the lung ventilator consists of various internal pneumatic circuits as
well as actuators designed to control the flow and the pressure of the medical gases. The
lung ventilator does not need to be connected to any medical gas distribution sources or to
devices that supply compressed air since this is done independently by an internal turbine.
The lung ventilator is able to deliver Air/Oxygen mixtures as it could be connected to an
external Oxygen source (please, refer to chapter n. 2).
1.4 Correct operation
For correct and complete operation, the Aria 104 must be:
correctly connected to the patient circuit;
connected to a mains power supply with the same voltage as specified on the
identification plate (or supplied by internal battery);
properly connected to all accessories and equipment necessary for the operation of the
lung ventilator;
if requested, connected to the O2outlets of the medical gas distribution system.
The connections with main power supply, as well as connections with
medical gas distribution system must be affected according to the
indications contained in the present user’s manual (see on chapter 2).
The Aria 104 incorporates a series of sensors for continuous patient monitoring, the most
important of which are:
the flow sensors on the expiratory (external) / inspiratory lines (internal), are used to
measure the expiratory / inspiratory volumes of the patient;
the pressure sensors (internal), used to control the pressure of the airways or of the
medical gases;
the oxygen sensor (external), used to measure the concentration of oxygen in the gas
inspired by the patient.

1-5
The output signals (from the, pressure, flow and oxygen sensors) are
filtered by an R-C circuit from the input circuits. This particular electronic
filtering is used to eliminate disturbances before the signals themselves
are processed by the microprocessor.
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 ventilator and all its parts.
For its employ the Aria 104 has been designed and made to guarantee
the 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.

SIARE Engineering International Group s.r.l. recommends careful reading
of this manual and the relative labels before operating the lung ventilator
or carrying out any maintenance.
1.4.1 Use
The use of Aria 104 lung ventilator is simple and intuitive for the persons skilled on
resuscitation ventilators, a short training course is in enough to learn how to use it. A basic
user interface: keyboard, encoder knob and a 10.4” touch screen display simplifying the
selection of the most suitable settings. The 10.4” touch screen display, ventilator settings
and the measured data, as well as several functions, allowing the clinician to asses
patient's condition immediately; you can also select and view the trend of the pressure,
flow, volume, flow/volume loops, pressure/volume, pressure/flow, over time.
An immediate information management system allows the clinician to set the alarms, collect
data concerning the trend of the operating parameters (TREND) and the ventilator EVENTS
log using the MENU. The same system allows the User to set the patient type (neonates,
children, adults), load or erase the PATIENT DATA and in case of need, to load
automatically the DEFAULT PARAMETERS of the lung ventilator.
