1 INTRODUCTION
This manual is expressly intended for SIARE qualified personnel or for qualified technical personnel,
officially authorized by SIARE to maintain the SIRIO S2/T.
The present manual describes the SIRIO S2/T and its operation principles, by the aid of constructive,
electrical and pneumatic drawings.
The SIARE qualified personnel or the qualified technical personnel officially authorized by SIARE, must
know the complete content of the present manual, before performing the operations described here
below.
The technician authorized by SIARE is equipped with proper tools and spares and he is instructed to
operate for products preservation.

!
SIARE declines all responsibilities arising from technical intervention performed on the
equipment without a formal authorization by SIARE.
A proper and safe use of SIRIO S2/T lung ventilator both for the patient and the operator requires the
perfect knowledge of the recommendations and instructions indicated in the present manual.
1.1 Main characteristics of SIRIO S2/T
The portable SIRIO S2/T lung ventilator is specially designed to be used in emergency, first-aid, intrahospital transportation and it is destined to be applied on adults, children and newborns.
The following ventilation modes are featured:
•
at continuous flow (CPAP);
•
automatic ventilation through a time cycled breathing activity synchronized with the patient’s
spontaneous activity (AUT+ AST);
•
assisted with pressure support (PSV - Pressure Support Ventilation).
Among the default functions the following can be adjusted:
•
breathing cycle frequency in AUT+AST mode (Fix I:E Ratio 1:1,5);
•
delivered minute volume or flow;
•
max airway pressure limit in AUT+AST mode;
•
pressure support level in PSV;
!
DU5051114
•
oxygen concentration (MIXER 50 or 100%).
SIRIO S2/T measures and displays:
•
the instant airways pressure;
•
the spontaneous patient activity in AUT+ AST and PSV modes;
•
an eventual alarm status (LOW PAW/APNEA, GAS SUPPLY, LOW BATT, HIGH PAW/LIMIT,
POWER FAILURE).
The ventilation of critical patients without continuous control must be effected by using an
external spirometer having alarms on minute volume.

1.2 Operating
For a correct and complete operating the equipment must be connected to the medical gas distribution
system outlet or to the cylinder outlet.
Sirio S2 / T
In order to supply mixtures at 21% O
this case the adjustment of the mixer at 50% and 100% values will not affect the concentration.
SIRIO S2/T has a built-in battery that allows it to operate for at least 6 hours when the battery is fully
charged and in good operating order.
An external 12 Vdc battery (from an ambulance, helicopter, etc...) can also be used as a source of
power for SIRIO S2/T .
SIRIO S2/T includes an airway pressure gauge for measuring the patient’s airway pressure, a patient’s
spontaneous activity sensor and a sensor that activates an alarm for low airway pressure.
It is necessary to check these sensors before using them, in order to avoid incorrect evaluation of the
patient’s ventilation. The test procedures are described in chapter 4 of this manual.
The electrical and medical gas system connections should be made as per the procedures described in
chapter 4.
1.3 Norms
SIRIO S2/T is a lung ventilator manufactured according to the following norms:
CEI 62-5 : 1991 (EN 60601-1)
UNI EN 794-3

ALARM RESET: for safety reasons the acoustic alarm silencer operates for 20 seconds, the
alarm is enabled again whenever the airway pressure exceeds 8 cmH
This key also allows to silence the POWER FAILURE ALARM. In critical patients, especially
when the operator is not present, it is good practice to connect a breathing monitor in order to
verify the ventilation from a volumetric point of view also, not just from a pressure point of view.
