Installation Checkout Procedure
31. Check each vaporizer's agent concentration output and accuracy.
a.
Insert the agent measuring device sampling tube inside the common gas outlet port.
b.
Fill the Vaporizer with anesthetic agent.
NOTE:
Do not overfill by filling past the indicator line on the
vaporizer.
c.
Test the vaporizer accuracy per the Vapor 2000 instructions or see the appropriate
vaporizer manual for testing details.
d.
Test each vaporizer in turn.
e.
Test any vaporizer on the Vaporizer Storage Mount.
f.
Remove the measuring device from the common gas outlet port.
g.
Connect the fresh gas tube to the common gas outlet port.
32. Dräger Vapor 2000 Operating Instructions ARRB-F001.
a.
Fill Vaporizer - at least half full between minimum and maximum mark.
b.
Allow the filled Vapor to warm up to room temperature of 20-24
C. Wait long
enough for the temperature to equalize - the time will vary depending on the
temperature differential '
T
'.
• 1 hour = up top 2
C
• 3 hours = ±6
C
• 4 hours = ±10
C
• 5 hours = ±20

c.
Check anesthetic agent monitor. Perform zero calibration of monitor with the desired
gas (AIR or O
2
)
d.
Connect monitor to fresh gas outlet or Y-fitting. Make sure that all connections are
leak-tight.
e.
Connect and start scavenging system.
f.
Switch OFF ventilator or set vent pressure to less than 5 cmH

O.
g.
Set monitor to anesthetic agent being used and to continuous measurement.
h.
Set flow between 2.5 and 4 L/min AIR. Use O
2
if AIR is not available.
i.
Check
0
and
T
marks, 1 vol.% 4 vol % and at least three other concentrations.
j.
Adjust control dial on the vaporizer.
k.
Read concentration after it has reached steady state.
l.
Correct measured values for the effect of carrier gas used. If AIR no correction
required. If O
2
use following correction factor:
• Measured value vol.% = <1.0, correction = -0.05 vol.%
• Measured value vol.% = 1.0 - 2.0, correction = -0.1 vol.%
• Measured value vol.% = 2.5 - 4.0, correction = -0.2 vol.%
• Measured value vol.% = 5.0 - 8.0, correction = -0.3 vol.%
m.
If the value displayed on the monitor is in % partial pressure, no correction is
required. If in vol.% convert to partial pressure:
• Concentration [% partial pressure] = measured value [vol.%] x atmospheric
pressure [cmH
2
O] / 1013 cmH
