Safety
Please read the safety information before using the Vevo Compact
Anesthesia System. The following information applies to the Vevo
Compact Anesthesia System and its modules.
The use of this equipment must be directed by, is intended for use by, and
under the supervision of qualified research scientists.
Read all warnings and cautions carefully before use!
Warnings are precautions necessary to prevent injury
or loss of life.
Cautions are precautions necessary to protect the equipment.
WARNINGS

• For small animal use only. Not for human use.
• Do not fill the vaporizer with any anesthetic agent other than the one
specified on the front label. The vaporizer is designed for that agent
only. Any other agent than that specified can prove to be dangerous
to a subject.
• If a vaporizer is filled with the wrong agent, draining will not
eliminate the agent since some of the agent will have been absorbed
into the wick. The wick must be thoroughly cleaned and dried. This
procedure must be performed at an authorized service center.
• Do not carry the vaporizer by the control dial.
• Do not modify, tamper with, or disassemble the vaporizer. There is a
potential danger of damaging the vaporizer and altering the
calibration accuracy.
• Do not immerse the vaporizer in any liquid, including water.
• Do not sterilize the vaporizer.
• Do not drain the anesthetic agent into any container other than a
properly marked container.
• Incomplete sealing of the fill cap will result in loss of gases.
• Do not fill the vaporizer unless the control dial is in the ‘Off’ position.
• Do not turn the dial ‘On’ during filling or attempt to fill beyond the
‘Full’ mark.

• Keep the vaporizer upright at all times.
• Never tilt a calibrated vaporizer beyond 45 degrees when charged.
Dangerous overdose may result during subsequent use. This
condition can be detected by calibration verification only.
• Do not connect the vaporizer directly into the patient breathing
circuit.
• Do not turn on two vaporizers at the same time.
• Do not put water or any other solvent in a vaporizer.
• Due to the wick’s capacity to absorb agent, the vaporizer will
continue to deliver the set concentration for a considerable period of
time even if no liquid level can be viewed through the sight window.
However, do not use a vaporizer in this condition on a subject.
• Flush flows through an open vaporizer may result in unwanted
concentrations of anesthetic agent.
• Do not ignore maintenance of your vaporizer. An annual calibration
recertification is highly recommended by the manufacturer.
CAUTIONS

• Personnel operating this compact anesthesia system must be
thoroughly familiar with the instruction manual and equipment
operation prior to use with subjects.
• Tampering with the anesthesia system components by unauthorized
personnel voids all warranties and specifications. The prevention of
tampering with the anesthesia system is the sole responsibility of the
user or owner. VisualSonics assumes no liability for any malfunction,
failure, damage or loss to either equipment or life.
• Before using the anesthesia system check that it is set up properly,
ensure all connections and settings are correct.
• Always adhere to proper Diameter Index Safety System (D.I.S.S.)
hose connections. Failure to comply will void your warranty and
could compromise subject safety.
• Remove the machine from service if:
a. the oxygen flush button does not immediately return to the OFF
position after being released, or
b. the flow of oxygen does not immediately stop flowing from the
common outlet after the oxygen flush button is released.
Then call VisualSonics or a VisualSonics-authorized service
facility to repair the valve.
• If the oxygen flush button does not immediately return to the off
position after being released, or if the flow of oxygen does not
immediately stop flowing from the common outlet after the oxygen

flush button is released, remove the machine from service. Have the
valve repaired by VisualSonics or a VisualSonics-authorized service
facility before using the machine.
• When you turn off the flowmeter, turn the control knob clockwise
just far enough so the ball float reaches the bottom of the tube.
Continuing to tighten the control knob will damage the valve seat
and cause a leak. The unit will need to be replaced when this damage
occurs.
• Vaporizer should be serviced by an authorized service center.
• Turn the vaporizer ‘Off’ when not in use.
• A vaporizer MUST be in a vertical upright position to indicate liquid
agent levels accurately.
• If a screw-cap filler vaporizer is pressurized, turn the screw slowly
before filling.
• The delivered concentration may be different from the set
concentration if the vaporizer is operated in a tilted position.
• Avoid kinks in the tubing that will restrict flow. Eliminate leaks that
will affect total flow to the subject.
• To fill the vaporizer when in use, it will be necessary to turn the
vaporizer off.
• No repair should ever be undertaken or attempted by anyone not
having the training and qualifications to perform these tasks.
