Tests
5. Wait until the pressure stabilizes between 15 and 30 hPa.
– When the pressure has stabilized, continue with the check, see step 6.
– If the pressure continues to fall, there is a leakage present. Decide whether
6. Set the vaporizer to the smallest delivery setting. To do this, turn the control dial
from the 0 position to the first mark on the scale.
7. Observe the breathing system pressure. The pressure must remain stable and
may only drop at a minimally slow rate.
If the pressure drops faster, the vaporizer is leaking.
8. Close the vaporizer. To do this, set the control dial to the 0 position.
9. Exit the System test again. To do this, touch the Cancel button.
For leaky vaporizers, the compete leakage test can be used to determine how large
the leakage is.
Complete leakage test
Testing the vaporizer in the closed state:
1. Touch the Tests... button.
2. Touch the Leakage test button.
3. Perform the leakage test with the vaporizer closed.
If no leakage value is displayed, the test has passed. If the determined leakage
is at least 500 mL, the leakage value Leakage (total) is displayed.
Testing the vaporizer in the open state:
1. Touch the Tests... button.
2. Touch the Leakage test button.
3. Set the vaporizer to the smallest delivery setting. To do this, turn the control dial
from the 0 position to the first mark on the scale.
4. Perform the leakage test with the vaporizer opened.
If no leakage value is displayed, the test has passed. If the determined leakage
is at least 500 mL, the leakage value Leakage (total) is displayed.
5. Close the vaporizer. To do this, set the control dial to the 0 position.
6. Press the O
system will be flushed and the residual anesthetic agent will be disposed of in
the AGS.
Using the determined values, the user can decide whether the vaporizer can be
used.

Manual check of a coaxial breathing circuit for leaks
Leakage in the inner hoses of coaxial breathing circuits cannot be detected with the
normal system test. A special test adapter is used to determine the leakage in
Dräger coaxial breathing circuits. The following checks are possible:
– Quick tightness check: Checks whether there is leakage.
– Complete leakage test: Determines the leakage value.
For both checks, first the inner inspiratory hose and then the outer expiratory hose
is tested.
