Pre-Use Checkout Procedure - Dräger NARKOMED 3 Operator's Instruction Manual

PRE-USE CHECKOUT PROCEDURE

Prior to operating the NARKOMED 3, the fol-
lowing checkout procedures shall be performed
to ensure that the machine is ready for use. If
the anesthesia machine fails any of the
procedures identified by an asterisk (*), do not
use the machine, and contact an authorized
North American Dräger service representative.
NOTE: Do not insert
components into the anesthesia system after
the checkout procedure has been started.
1. Enter the anesthesia machine serial
number, located on the right rear leg,
into the anesthesia record.
2. Verify the presence of a valid
inspection sticker on the rear of the
NARKOMED 3, indicating that the
anesthesia machine has been serviced
and inspected by an authorized North
A m e r i c a n
representative.
3. Verify the presence of a reserve
cylinder wrench, tethered to the rear of
the anesthesia machine, adjacent to
one of the reserve cylinders.
4. Connect the electrical power cable to a
live 117 VAC or 240 VAC receptacle
that will accept and properly ground
the anesthesia unit's line power cable.
DO NOT use "cheater" plugs.
5. Connect the hospital pipeline supply
hoses from the anesthesia machine's
DISS fittings to the appropriate wall
outlet DISS fittings.
*6. Calibrate the oxygen sensor: Expose
the oxygen sensor to ambient air and
perform a calibration. (See the Oxygen
Analyzer section of this manual for
details.)

*7. Verify that the correct gases are
supplied to the anesthesia machine
inlets.
*8. Inspect the supply hoses for cracks or
wear.
*9. Check for sufficient pipeline pressure:
The pressure for each gas, indicated on
the pipeline pressure gauge below the
flow control valves, should be 50 - 55
psi. Open the flow control valve for
each gas to a moderate value; the
pressure indicated at the pipeline
pressure gauge shall not decrease more
than 5 psi.
*10. Check the oxygen cylinder supplies:
A. Verify the existence of 2 index pins
in the yoke, and mount cylinder(s).
B. Disconnect the oxygen pipeline
supply (if connected). With the reserve
oxygen cylinder(s) closed, actuate the
oxygen flush button on the front of the
anesthesia machine. Hold the button in
until pipeline and cylinder pressure
gauges indicate zero pressure.
C. Open the oxygen cylinder (or one of
the cylinders if equipped with dual
yokes) and check the cylinder pressure
gauge. A full oxygen cylinder should
indicate a pressure of about 2200 psi.
Replace any cylinder with a pressure
less than 600 psi. At least one cylinder
should be nearly full. Adjust flow over
the full range of the flowmeter and
verify that maximum flow can be
achieved. Close the flow control valve.
Then, to check for a high pressure
leak, close the cylinder and observe the
cylinder pressure gauge for a decrease
of the pressure indication.
