Pipeline Supply
System Verification
*11. Pipeline Supply Verification
A. Inspect the supply hoses for cracks or wear.
B. Connect the appropriate hospital pipeline supply hoses
from the wall outlet fittings to the pipeline inlet
connectors.
C. Check for sufficient pipeline pressure readings for each gas
on the pipeline pressure gauges located below the flow
control valves. The pressure for each gas must be between
50–55 psi. Open the flow control valve for each gas to a
moderate value. The pressure indicated at the pipeline
pressure gauge must not decrease more than 5 psi.
D. Verify that the correct gases are supplied to the anesthesia
machine inlets.
Low Pressure
System Verification
*12. Vaporizer Verification
A. Check for sufficient supply of liquid anesthetic in the
vaporizer(s). The liquid level indicated in the vaporizer
sight glass must be between the minimum and maximum
markings.
B. Make sure the fill and drain valves are completely closed.
C. Check the vaporizer exclusion device, which prevents more
than one vaporizer from being activated simultaneously.
Make sure that when one vaporizer handwheel is turned
to a setting greater than 0, the others remain locked in
their 0 positions. Test all of the vaporizer positions. Then,
turn all vaporizers to the 0 position.
System Gas Circuit
Verification
*13. Check the flowmeters. Adjust the flow control knob for each gas
and verify the proper operation of the corresponding flowmeters.
The float must move freely over the full range of each flowmeter.
Oxygen Monitor
Calibration
*14. Calibrate the oxygen monitor by exposing the sensor to ambient
air and activate the calibration key. (See Operation - Oxygen
Monitoring “Calibrating the Oxygen Sensor” in Section 5 for more
information.)
A. Place the oxygen sensor securely in the sensor mount.
B. Verify that the correct gas concentrations are supplied to
the anesthesia system from the supply cylinders.
