WARNIN
Anaesthesa systems have the capablty to delver mxtures
of gases and vapours to the patent whch could cause nury
or death unless controlled by a qualfed anaesthetst
There can be consderable varaton n the effect of
anaesthetc drugs on ndvdual patents so that the settng
and observaton of control levels on the anaesthesa system
does not n tself ensure total patent safety
Anaesthesa system montors and patent montors are very
desrable ads for the anaesthetst but are not true clncal
montors as the condton of the patent s also dependent
on hs respraton and the functonng of hs cardo-vascular
system

OBSERVATIONS ARE IVEN PREEDENE OVER MAHINE
ONTROL PARAMETERS IN JUDIN THE STATE OF A
LINIAL PROEDURE
Before usng any montorng system or devce, the user must

Prma 465 Anaesthetc Machne 2 User Manual
1. Warnings and Cautions
The following WARNINGS and CAUTIONS must be read and
understood before using this anaesthesia system.
Warnngs
1 Ths anaesthesa system s desgned for use only wth
non-flammable anaesthetc agents It must not be used
wth or n close proxmty to flammable anaesthetc
agents, due to a possble fre or exploson hazard
2 Exteror panels must not be removed by unauthorsed
personnel and the anaesthesa system must not be
operated wth such panels mssng Unauthorsed
personnel must not attempt to access fuses or other
electrcal components There s a possble electrc shock
hazard
3 To solate the machne from the mans power supply,
dsconnect the mans cable from the hosptal power
outlet
Always use a mans power outlet socket that can be
easly accessed
4 No ol, grease or other flammable lubrcant or sealant
must be used on any part of the machne n close
proxmty to medcal gas dstrbuton components
There s a rsk of fre or exploson
5 Attachng or removng a medcal gas cylnder
a) Follow approprate manual handlng gudelnes
when lftng
b) heck that the machne yoke and cylnder faces are
dust free and clean and that the sealng washer
provded s n poston between the cylnder valve
and the yoke
c) Tghten the yoke securely before openng the
cylnder valve Dust and drt presents a fre hazard n
the presence of hgh pressure gas Leakage of hgh
pressure gas can cause serous nury
6 The anaesthesa system must be connected to an
anaesthetc gas scavengng system (ASS) to dspose
of waste gas and prevent possble health hazards to
operatng room staff
Ths requrement must be observed durng test
procedures as well as durng use wth a patent
7 Ths machne must only be used wth Selectatec-
compatble vaporzers nstalled on the backbar
Free-standng vaporzers may be accdentally tpped,
resultng n excessve and uncalbrated volumes of
anaesthetc drug enterng the breathng system
8 Only vaporzers wth the Selectatec-compatble nterlock
functon wll nterlock f nstalled on the backbar
The nstallaton of non-nterlock vaporzers allows the
possble operaton of more than one vaporzer at the
same tme
9 The breathng system whch conveys gases from the
anaesthetc machne to the patent and dsposes of
expred gases s a vtal part of the anaesthetc delvery
system
Because breathng systems requre frequent cleanng
they are not a permanent part of the anaesthetc
machne and therefore cannot be drectly under the
control of the anaesthetc machne manufacturer When
mechancal ventlaton s employed the patent breathng
system must be connected drectly to an over-pressure
relef valve to prevent the possblty of barotrauma
10 Always perform a pre-use check of the machne,
ncludng vaporzers, ventlator, absorber and montors
before clncal use Follow the pre-use checklst (see
secton 52) as a mnmum requrement
Many clncal ncdents occur because of a falure to
check for correct functon
11 The system start-up test (secton 54) ncludes an
automatc system test Ths test ncludes system
calbraton tests If the screen dsplays a ‘Fal’ for the
Pressure sensor, Flow sensor, or Flowmeter zero
calbraton tests, follow the nstructons gven n
sectons 751, 752, and 76
DO NOT use any other procedures
If a ‘Fal’ error s stll dsplayed, contact a Penlon-traned
servce engneer
12 The machne must not be used f any of the alarm,
montorng, or protecton system devces are not
functonng correctly
13 Auxlary gas outlets Flow rates greater than 60 L/mn
could affect the fresh gas flow to the patent
14 When the auxlary gas outlets are n use on a machne
usng cylnder supply only (e f the ppelne supply s
not n use), check flow rate requrements, and check that
adequate back-up cylnders are avalable
15 Do not use the machne solely to provde large flows of
oxygen, va the anaesthetc machne auxlary outlets,
to external devces whch may not be equpped wth a
supply falure alarm
16 On machnes wth ppelne connectons only, note that a
malfuncton of the central gas supply wthn your faclty
may cause mmedate cessaton of gas delvery and total
anaesthesa system falure
17 To avod the rsk of electrc shock, ths system must only
be connected to a mans supply wth a protectve earth
Before any electrcally powered machne s used
clncally for the frst tme, check that the hosptal
engneerng department has carred out an earth
contnuty test
18 Before usng any addtonal electrcal equpment
powered by the auxlary sockets on the machne, check
that the addtonal equpment s correctly wred and s
earthed through ts plug
19 A mssng or defectve protectve earth conductor may
ncrease earth leakage currents to the patent to values
exceedng the allowable lmts, resultng n ventrcular
fbrllaton, or nterference wth the pumpng acton of
the heart

closer than 30 cm (12 nches) to any part of ths devce,
ncludng cables specfed by the manufacturer
Otherwse, degradaton of the performance of ths

c) All gas cylnders must be removed
23 MRI compatblty - Prma 465 models are not MRI

24 To prevent patent nury n the event of total anaesthesa
system falure, an alternatve means of ventlaton must
be avalable whenever the devce s n use
25 Obstructon of the breathng system can restrct or
stop gas flow to the patent, and can cause nury or
death Make sure that there are no obstructons n the
breathng system
26 Keep very small components/parts/plugs away from the
breathng system
27 Use non-conductve breathng system hoses
28 Do not touch any electrcal devce connector at the same

Warnings and Cautions
34 Ventlatng neonates (nfants)
a) Use only Pressure ontrol Ventlaton or Volume
ontrol ventlaton for mandatory ventlaton of
neonates
b) Always set a low target pressure frst and then

Warnings and Cautions
autons
1. Open cylinder valves slowly to avoid damage to
pressure reducing valves.
Check that cylinder valves are at least one full turn
open when in use.
2. Under no circumstances should anaesthetic agents be
used for cleaning purposes.
3. After use, always disconnect the machine from the
piped gas supply and/or close the gas cylinder valves.
4. Compressed gas supplies must be clean and dry.
5. The requirements of IEC 60601-1 apply to any device
connected to the auxiliary electrical sockets. Users
must be aware of the risks of increased leakage
currents when equipment is connected to the auxiliary
power sockets
6. In the event of malfunction of any device powered by
the auxiliary sockets, check if the circuit breaker has
tripped.
7. Do not apply excessive pressure to the display screens.
8. Connect the external RS232 outlet only to approved
devices using protocol provided by Penlon Ltd. Contact
Technical Support Department for details.
9. Vaporizers: Read the instruction manual supplied with
the vaporizer before clinical use.
