Basically there are three different variants for how FlowAnalyser can be connected
to the ventilator:
A: Downstream of the Y-piece
Note: It is advisable to have the inspiratory flow entering from the front (positive direc-
tion) and the expiration entering from the back (negative direction) of the unit.
If this is not the case trigger settings have to be modified for proper breath detection.
With default trigger settings inspiration becomes expiration and several parameters
will be calculated wrongly or not at all.
B: In the inspiratory channel upstream of the Y-piece
Note: default trigger settings require modification.
C: In the expiratory channel upstream of the Y-piece
Note: default trigger settings require modification.
