Te Anaesthetic Gas Scavenging(AGS) system is an active system
whichremoves anaesthetic gas mixtures romoperating rooms and any
other areasfitted with nitrous oxide terminal units.Te removal at
source thus eliminatesthe possible long term health hazardsto
exposed medical sta. By virtue oits design, the active disposal
systemcan produce high levels o capture
simply by connecting the terminal unitto the anaesthetic
breathing circuit viaa receiver unit, thereby removing themajority
o pollution at source.
Te AGS system is ully compatiblewith any AGS receiver
unit.BeaconMeds terminal unitsincorporate an adjustable orifice,
whichenables the ow rate to be adjusted inline with any standard
including BS
6834, EN 740 and EN ISO 7396-2high-ow ow and low-ow systems.Te
AGS system is activated by remoteswitches that can be installed at
anyconvenient location either in or closeby the operating and
anaesthetic room.
Key Benefts

Te chart and table below comparethe three main standards in use
oranaesthetic gas scavenging systems.BeaconMedaes AGS systems are
easilyadjusted to provide perormance tomatch any o the three.
It is increasingly common to use acentralised AGS system in
dentalapplications. Dental AGS systems are
generally dierent and do not requirethe AGS receiver unit
(commonlyknown as an air brake), which isnecessary or anaesthesia
duringsurgical procedures. A dental AGSsystem is normally required
to providea continuous ow o around 45l/min to ensure the sae and
efcientcollection o waste gases.
Duplex Systems
Where planned preventativemaintenance or a breakdowno a blower
could interrupt thesmooth running o the operatingdepartment, a
duplex system isstrongly recommended. In the evento a blower
malunction, the stand-byunit is automatically brought on
line,ensuring the AGS system continuesto provide protection or
medicalsta, and that operations do not haveto be delayed or
cancelled.
Please contact your localrepresentative or applications
anddesign support, and advice onequipment selection.
AGS Standards
Improvements in anaesthesiaworkstation designs have led
toreduced ows o gas being used, andhence less potential gas
spillageduring induction and maintenanceo anaesthesia. Over the
years, AGSsystem design standards have evolvedto take account o
this, but anaesthesiaworkstations in use today rangeanywhere rom a
ew days old to a ewdecades o service. Tis means thatlower ow
systems are not practical inall applications.
HM 02-01 provides guidance on theselection o an appropriate
standardor system ows based in a number opractical scenarios.
