1.1.8 Active Anesthetic Gas Scavenging System
1.1.8.1 Anesthetic Gas Scavenging System (AGSS)
The A5/A3 includes a waste gas scavenger that attaches to the side rail mount on the system. The A5/
A3 provides a port for the connection of the waste line from an anesthetic gas monitor.
1.1.8.2 Dynamic Gas Scavenging System (DGSS) (Optional)
The Dynamic Gas Scavenging System (DGSS) is composed of the DGSS transfer system, the DGSS
receiving system, and the DGSS disposal system. Waste gas goes from the exhaust port of the
anesthesia machine through the DGSS transfer system and the DGSS receiving system to the
hospital's waste gas disposal system (DGSS disposal system).
1.1.9 Passive Anesthetic Gas Scavenging System (Optional)
The A5/A3 includes a passive waste gas scavenger. The inlet port of the scavenger connects with the
AGSS port and the exhaust port connects with the hospital's waste gas scavenging system.
1.1.10 Power Management / Battery Supply
The advanced power management system of the A5/A3 provides AC power for main system
functions while charging the system’s internal battery supply. During AC power failure, the A5/A3 will
operate on battery power for a minimum of 75 minutes with one (1) new battery installed (A3) or 150
minutes with two (2) new batteries installed (A5). See
‘‘Battery Power Specifications’’ on page 9-7.
A recessed main switch is provided to power the system On and to put the system on power standby
where the battery supply continues to charge as necessary when the A5/A3 is plugged into an
external power source. The main switch also stops the O
2
fresh gas supply when the A5/A3 is placed
in Power Standby mode.
Auxiliary AC outlets on the rear of the machine operate independently of the main switch position.
The A5 provides four (4) auxiliary AC outlets; the A3 provides three (3) auxiliary AC outlets. The
auxiliary AC outlets are not powered when operating the A5/A3 on the internal battery supply.
NOTE: Use the battery supply in the A5/A3 at least once every month to
extend battery life. Charge the battery supply before its power capacity
is depleted.
