When the breathing bag is full, any excess gas mixture flows through the
non-return valve into the anesthetic gas scavenging system.
The CO2 is scrubbed from the expiratory gas by the soda lime contained in
the absorber. The fresh gas replaces the anesthetic and oxygen taken up by
the patient.
Spontaneous Breathing: Expiration - Typical for Breathing System P/N
4118378 or 4118379
During expiration, the inspiratory valve remains closed thus preventing the
expiratory gas from flowing back into the inspiratory branch.
The APL valve is open, regardless of its pressure setting.
