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).

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 O
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.

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).
