Valves group - Breathing system

The valves group (or also the breathing system) is the device that conveys the fresh gases (coming
from anaesthesia module) to the patient; collects the exhaust gases and conveys them to the CO
absorber canister, and then toward the bellow of valves group to be delivered to the patient

non-rebreathing modality (real open circuit). It is possible to insert and remove the canister during
intervention.
When using the valves group in non-rebreathing, a greater amount of fresh gases must be delivered
with respect to the Minute Volume value set on the anaesthesia unit.
In any case, the anaesthesia unit ensures that the patient receives the Minute Volume by aspirating
the missing amount from ambient air, through the apposite safety valve, but, in this case, patient
anaesthesia is not guaranteed as the N
insufficient percentage in the gas mixture.
The manual ventilation is possible directly from the valves group (AUX connector) or with the TO and
FRO external system.

Main features.
•
Perfect integration with the work-shelf, upper extraction by
apposite handle; completely autoclavable.
•
Automatic connections with double tightness gaskets to prevent
accidental leakages.
•
It allows to ventilate in modalities: real open circuit, semi-closed
circuit, closed circuit at low flows.
•
It allows the spontaneous and manual ventilation also in case of
anaesthesia unit failure or machine off.
•
The gas recycling system is of selective type; therefore, the soda
lime consumption of fresh gases is optimized.
•
It's heated to reduce the accumulation of condensate and to heat
the fresh gases.
•
The passage to a ventilation modality to another is completely
controlled by the anaesthesia unit without any user's action on
valves group.
•
The flow and oxygen sensor calibration are completely automatic
and it does not require particular manual operations.
•
Thanks to the extreme rationality of the system and to the drastic
reduction of accidental leakages, the preventive and extraordinary
maintenance operations are reduced to a minimum.
