Section 5 - Operation
Vaporizer
Turning the
Vaporizer Off
To turn the vaporizer off, turn the vaporizer handwheel to “0” (zero-point
interlock) and make sure the button engages. Do not interrupt the fresh
gas flow until you have turned off the vaporizer.
NOTE: If you will not be using the vaporizer for a long period of
time (longer than one month), or if the vaporizer will be
removed from the anesthesia machine, drain the
anesthetic agent from the vaporizer.
Filling the Vaporizer
Before filling a vaporizer, identify the filling system on the device as one
of the following:
• Open funnel system
• Key indexed safety system
When you have identified the filling system, locate the appropriate
procedure and read it entirely before filling the device.
WARNING: Do not inhale anesthetic vapors while filling the vaporizer.
Uncontrolled inhalation of anesthetic vapors is injurious to
health.
Before filling a vaporizer, note the expiration date of the anesthetic
agent. Do not use anesthetics beyond the date of expiration.
CAUTION: Each vaporizer is specifically designed and calibrated for
one particular anesthetic agent. Do not fill a vaporizer
with any anesthetic other than the particular agent
indicated on the vaporizer.
• The Isoflurane vaporizer must be filled with Isoflurane
only (trade names: Forane, Forene, Aerrane).
• The Enflurane vaporizer must be filled with Enflurane
only (trade names: Ethrane, Alyrane).
• The Halothane vaporizer must be filled with Halothane
only (trade name: Fluothane).
• The Desflurane vaporizer must be filled with
Desflurane only (trade name: Suprane).
• The Sevoflurane vaporizer must be filled with
Sevoflurane only (trade name: Ultane).
Do not use a vaporizer that has been inadvertently filled with the wrong
anesthetic. Drain the vaporizer and return the device to North American
Dräger’s Technical Service Department.
