contnuty test If the ntegrty of the protectve conductor
s n doubt, do not use the ventlator
5 Excessve electronc nose caused by other poorly
regulated devces, such as an electrocautery unt, may
adversely nterfere the functonng of the ventlator

perpherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12
nches) to any part of the ventlator, ncludng cables
specfed by the manufacturer Otherwse, degradaton of
the performance of ths equpment could result
8 The drvng gas supply must be clean and dry to prevent

13 Breathng System
The breathng system whch conveys gases from the
ventlator to the patent, and dsposes of expred gases,
must conform to the requrements of ISO80601-2-13
Because breathng systems requre frequent cleanng
and dsnfecton they are not a permanent part of the
ventlator and therefore cannot be drectly under the
control of the manufacturer However, we strongly
recommend that only breathng systems whch have been
approved and authorsed by the manufacturer for use
wth the ventlator should be employed
