The Bag/Vent switch closes the manual path (V). Pilot pressure (P) closes the
exhalation valve.
Drive gas (D) pushes down on the bellows. Gas flows from the bellows (1), through the
absorber (2a), Condenser (2b), and through a unidirectional valve (inspiratory check
valve) to the patient (3).
During inspiration, fresh gas flows into the inspiratory limb, upstream of the inspiratory
check valve.
