Filling The Vaporizer During A Case - Dräger Narkomed 2B Operator's Instruction Manual

Filling the Vaporizer
During a Case
Filling Vaporizer
With Open Funnel
System
If you must fill the vaporizer during a case, be extremely careful. While
fresh gas is flowing and the vaporizer is turned on, the vaporizing
chamber is pressurized. DO NOT open the inlet valve (or the screw of
the safety filling device) under these circumstances — liquid anesthetic
may gush out. To safely add anesthetic agent while the machine is in
use, depressurize the vaporizer by setting the handwheel to "0" (zero-
point interlock); make sure the button engages in the locked position.
Allow at least 5 seconds for the vaporizing chamber to depressurize, then
use the appropriate procedure to add the anesthetic agent.
WARNING: The vaporizer handwheel must be set to "0" (zero-point
interlock) before the vaporizer can be filled.
1. With the vaporizer in an upright position, turn the handwheel to "0"
(zero-point interlock) and make sure the button engages in the locked
position.
2. Make sure the filling spout is clean. To remove dust or other
particles, use a clean, dry paper towel. Do not use water or other
liquid cleaning solutions.
3. Make sure the drain valve is closed.
4. Open the inlet valve by turning it counterclockwise about three
turns.
CAUTION: Be sure to fill the vaporizer in an upright position; filling
the vaporizer in a tilted position may cause overfilling.
Overfilling may cause the anesthetic concentration rate to
be higher or lower than the handwheel setting.
5. Remove the cap from the anesthetic agent bottle. Check the sealing
edge of the bottle for chipping or other damage. DO NOT use if
damaged.
