In case of mechanical ventilation, during inspiration, gas flows through bag/mechanical
ventilation switch 41, BYPASS valve 35 or sodalime canister 34, inspiratory valve 33, O2
sensor 39, airway pressure gauge 47, and inspiratory flow sensor 37 to the patient. During
expiration, gas flows through expiratory flow sensor 38, expiratory valve 36 and
bag/mechanical ventilation switch 41 to the folding bag. Airway pressure is monitored by
pressure sensor 53.
The breathing system is easily disassembled and is autoclavable at 134
℃

2.2.4.5 Anesthetic Gas Scavenging System
The anesthetic gas scavenging system (AGSS) is composed of AGSS transfer system, AGSS
receiving system and AGSS disposal system. Waste gas goes from the exhaust port of the
anesthesia machine through the AGSS transfer system and the AGSS receiving system and to
the hospital’s waste gas disposal system (AGSS disposal system), as shown below.
The following figure shows the operational theory of the AGSS. The throttling holes reduce
the effect of negative pressure at the AGSS outlet onto the flow at the entrance. The float
helps the user to learn if the disposal system meets the requirement for minimum pump rate.
The filter filters foreign substance to prevent the disposal system from being occluded. The
gas reservoir is connected to the air through pressure compensation openings. When positive
