6 Compact Breathing System "Cosy" /
Circle Absorption System "Circle System 9 Fabius"
Fabius is either equipped with a compact breathing system "Cosy" or with a circle
absorption system "Circle System 9 Fabius". They have the same function.
6.1 Compact Breathing System "Cosy"
The compact breathing system "Cosy" allows three modes of patient ventilation:
manual ventilation, spontaneous breathing, intermittent positive pressure ventilation
(IPPV). The APL valve (adjustable pressure limiting valve) has a selector which can
be used to toggle between "MAN" and "IPPV/SPONT".
In the "MAN" position, the compact breathing system is closed to atmosphere. This
position is the default position for manual ventilation of the patient. The APL valve
opening pressure can be adjusted from 5 to 70 hPa (mbar).
In the "IPPV/SPONT" position the APL valve is open to atmosphere. This position is
the default position for intermittent positive pressure ventilation and spontaneous
breathing.
The pressure limit (Pmax) can also be adjusted during IPPV from 20 hPa (mbar) to
70 hPa (mbar) using the control box.
