4.3.3 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 unit (first
connection or first replacement of hoses or connectors for maintenance reasons).
CAUTION
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 ( if supplied ), 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).
3. Connect to the hospital gas system only the Nitrous Oxide hose, select N2O 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 N2O 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.
