The Bag/Vent switch closes the ventilator path (B). . . .
Gas flows from the bag (1), through the absorber (2), into the breathing circuit module,
and through a unidirectional valve (inspiratory check valve) to the patient (3).
During inspiration, fresh gas (FG) flows from the machine into the inspiratory limb,
upstream of the inspiratory check valve.
