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 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).
2.
Connect to the hospital gas system only the Oxygen hose and open the
three 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
3.
N 2 O 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.
