The expiratory gas flows from the lung through the expiratory hose, the flow
sensor, the PEEP control valve, the expiratory valve, the breathing bag, and
through the absorber. At the same time, new fresh gas flows into the breath-
ing bag.
When the breathing bag is full, any excess gas mixture flows through the
non-return valve into the anesthetic gas scavenging system.
Volume Control Mode: General
A prerequisite for volume control is that the patient is supplied with a sufficient
amount of fresh gas.
The APL bypass valve opens in volume mode, allowing excess gas to be
vented to the scavenging system regardless of the MAN-SPONT valve set-
ting.
