WARNING! Risk of explosion.
If the pressure reducers for O 2 are touched with fingers/hands soiled
with oil or grease, there is the risk of explosion.
Do not apply oil or grease on the O 2 cylinders pressure reducers and
never touch with fingers soiled with oil or grease.
6.3.3 Medical gas connection checks
WARNING! Risk of gas power failure.
This check is strictly necessary and has to be performed whenever a
hose from hospital gas distribution system or cylinder supply is mounted
on the machine (first connection or first replacement of hoses or
connectors for maintenance reasons).
Only highly qualified personnel can fit the anaesthesia unit with
connectors compatible with the hospital medical gas distribution system
and perform all maintenance and replacement of medical gas supply
hoses so as to avoid inversion of gas that can be FATAL for the patient.
Follow these instructions
1.
Connect to the main gas system only the AIR hose, select AIR on the
anaesthesia module and open the three regulators of the anaesthesia module.
Only the AIR flowmeter should raise and its relevant pressure gauge should
indicate a pressure included between 280 kPa and 600 kPa (2,8 – 6 bar).
Connect to the hospital gas system only the Oxygen hose and open the three
2.
regulators of the anaesthesia module. Only the oxygen flowmeter should raise
and its relevant pressure gauge should indicate a pressure included between
280 kPa and 600 kPa (2,8 – 6 bar).
Connect to the hospital gas system only the Nitrous Oxide hose, select N 2 O
3.
on the anaesthesia module and open the three regulators of the anaesthesia
module. Only the oxygen and nitrous oxide flowmeters should raise and the
relevant pressure gauge should indicate a pressure included between 280 kPa
and 600 kPa (2,8 – 6 bar).
4.
With open N 2 O pressure reducer, disconnect the Oxygen hose and verify that
the oxygen goes down, that the delivery of Nitrous Oxide stops and that the
CUT-OFF alarm whistle is audible.
