Main Technical Characteristics; Foreseen Use - Siare Siaretron 4000 User Manual

1.1.1 Main technical characteristics

The Siaretron 4000 lung ventilator is composed of two main blocks: the trolley and the lung
ventilator block. The trolley, if required, can be equipped with a built-in medical air
compressor.
In turn, the 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,
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 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 ventilator block can be used as a stand-alone part being separable from the trolley, by
positioning it on a flat surface. Obviously this operation can be done only in case the
medical air compressor is not provided within the trolley.

1.1.2 Foreseen 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 (optional) ventilation are available, thanks to an adjustable
minimum Tidal Volume from 20 ml to 3000 ml. (from 2 ml to 100 ml : optional). After the
switching-on of the lung ventilator it is possible to choice the patient type (Adult, Paediatric
or 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, APRV, SIGH, Non Invasive Ventilation (NIV APCV - NIV PSV), Drug Nebulizer
(NEB.) and Manual Ventilation (MAN).
In spontaneous ventilation mode, it ensures inspiratory flow up to 240 l/min, both with
control and support pressure.
The medical air compressor (optional) supplies compressed air to the ventilator block and it
can be used in spite of medical air distribution system or from cylinder.
