Active AGSS
Always verify the proper operation of any gas scavenging
system. Make sure the scavenging system is not
occluded.
There are several versions of the optional active Anesthesia Gas
Scavenging System (AGSS) available depending on the hospital’s
type of waste gas disposal system.
Each version has a two-liter reservoir to capture peak exhaust flows
that briefly exceed the extract flow. The disposal system normally
entrains room air through an air brake (located in a receiver
underneath the breathing system), but will spill from this port during
extended periods of high exhaust flow. Its effectiveness is limited by
the extract flow of the particular active AGSS device.
• The active low flow system is for use with high vacuum disposal
systems. It requires a vacuum system capable of a continuous
nominal flow of 36 l/min and 300 mmHg (12 inHg) or greater
vacuum pressure. A flow indicator on the system indicates when
the unit is in operation.
• The active high flow system is for use with low vacuum (blower
type) disposal systems. This requires a system capable of
providing a continuous nominal flow of 50 l/min. A flow indicator
on the system indicates when the unit is in operation.
• The active adjustable flow system provides the ability to adjust
the flow with a needle valve (located in a receiver underneath
the breathing system) and a visual indicator bag which should
be properly inflated. It requires a vacuum system capable of a
continuous nominal flow of 30 l/min and 300 mmHg (12 inHg) or
greater vacuum pressure.
• The active low flow system with a 12.7 mm hose barb connector
is for use with low vacuum disposal systems. It requires an
external system with flowmeter.
• The active low flow system with a 25 mm barb connector is for
use with low vacuum disposal systems. It requires an external
venturi/ejector system with 40 to 50 l/min extract flow. A flow
indicator on the system indicates when the unit is in operation.
• The active low flow system with 30 mm ISO taper is for use with
low vacuum disposal systems. It requires an external venturi/
ejector system with 40 to 50 l/min extract flow. A flow indicator
on the system indicates when the unit is in operation.
Connecting active AGSS with a flow indicator
To use the optional active AGSS on a system that has a flow
indicator, connect it as follows.
