Testing settings alarms for use with a double limb circuit

Connect a double limb patient circuit fitted with a MAQUET test lung to the ventilator and perform
the manual test.
Set up ACV mode, non-invasive, adult ventilation.
Set the ventilation parameters as follows:
•
V
T
•
PEEP = 0cmH
•
F = 15bpm;
•
Max flow ( ) = 23L/min (Ti = 1.3 or I/E = 1/2.0);
•
Trigger =
•
Flow shape = constant;
•
Start ventilation and perform the following operations.
