The CBRN filter fits into the iVent
TM
201 via an optional air inlet adapter (item 
M1161967).  Remove the air inlet filter from the iVent
TM
201 by turning it 
counterclockwise.  Then fasten the air inlet adapter to the CBRN filter by twisting 
it on clockwise.  Finally, screw the CBRN canister with the adapter into the air inlet 
adapter.

201 USER INTERFACE 
It is important to invest time to acquaint yourself with the iVent
TM
201 and how the 
Control Knob is integrated with the screen and the operation of the iVent
TM
201.   
Connect a test lung with an Rp20 resistor and patient circuit. Switch on the unit, 
and navigate through the features discussed in this section. Rotating the Control 
Knob at the menu level allows for easy, automatic selection of ventilation modes.  
Choosing the best parameter for a patient is as easy as switching on the 
iVent
TM
201 and selecting the patient’s ideal body weight.
