midmark VMS Anesthesia Machine
Product Information
The anesthesia machine is a medical device used by veterinary professionals
trained in anesthesia practice. The machine is available in various models,
including VMS, VMS Plus, and VMC, and is intended for use in veterinary
clinics and hospitals. The machine has various components, including a
scavenging/APL valve, occlusion valve (VMS & VMS Plus only), exhalation valve,
pressure gauge (manometer), safety valve (negative pressure relief),
inhalation valve, flowmeter, oxygen supply fitting, oxygen flush, flowmeter
adjustment knob, breathing circuit, fresh gas connection, absorber canister,
vaporizer (not included), breathing bag, and more.
The installation of the anesthesia machine should be done carefully as per the
instructions provided in the manual. Wall-mounted machines should only be
installed in wood stud or concrete walls. The machine should not be installed
in a vehicle or any other confined space. Waste gases from the machine could
cause impairment to the occupants. The machine should be installed by a
licensed veterinarian or a professional trained in anesthesia practice.
Product Usage Instructions
- Remove the contents from the cartons and place the base with casters on the floor.
- For wood stud mounting, use #12 x 2 1/2 wood screw and #12 x 5/8 flat washer to mount the wall bracket to the wood stud through 1/2 min drywall. Two screws are required for each mounting.
- For concrete wall mounting, drill a hole in the wall for #12 lead anchor as instructed by anchor manufacturer. Drive the anchor into the wall and use #12 x 2 screw and #12 x 5/8 flat washer to screw the wall bracket into the anchor. Repeat for each mounting hole.
- Install the tapered end of the mounting column into the base.
- Install the absorber/drawer/shelf assembly into the column/stud.
Note: The mounting hardware is not included for wall installation. Refer
to the chase installation manual for mounting hole locations. To install VMS,
use hardware included with chase cabinet (5/16 bolts, washers, and nuts).

Mounting
Stand Mounted Units Only
-
Step 1: Remove contents from cartons. Place base with casters on floor.
-
Step 2: Install tapered end of mounting column into base.
Note
Mounting hardware not included for wall installation.
Wood Stud Mounting
Use #12 x 2 1/2” wood screw and #12 x 5/8” flat washer to mount wall bracket to wood stud thru 1/2” min dry wall.
Note: Two screws are required for each mounting.
Concrete Wall
Mounting- Drill hole in wall for #12 lead anchor as instructed by anchor manufacturer.
- Drive anchor in wall.
- Use #12 x 2” screw and #12 x 5/8” flat washer to screw wall bracket into anchor.
Note: Repeat for each mounting hole.
Note
Refer to chase installation manual for mounting hole locations. To install VMS, use hardware included with chase cabinet. (5/16” bolts, washers and nuts)
-
Step 3 : Install absorber/drawer/shelf assembly into column/stud.
-
Step 4: Install vaporizer.
Note: Vaporizer is not included with anesthesia machine, however the mounting kit and 10 mm nut driver for vaporizer installation is included.
-
Step 5: Install tubing, breathing bag and breathing circuit.
-
Step 6: Unlock canister latches.
Remove canister from side of assembly.
Fill with absorbent according to specifications on canister label. Reinstall canister and secure latches.
-
Step 7: Connect oxygen tank and perform leak test.
To perform leak test…
- Close APL (Scavenging /Adjustable Pressure Limiting) valve by turning knob clockwise.
- Place thumb over patient connection of breathing circuit
- Remove breathing bag and cover bag port opening. (Use palm of hand that is covering
- With oxygen (50-55 PSI [3.4-3.8 Bar]) supplied to anesthesia machine, slowly open flowmeter to register 30cm H20 on anesthesia machine pressure gauge.
- Turn off flowmeter when pressure reaches 30cm H2O. (If pressure holds steady the system is leak free but if pressure drops, proceed to step (F).)
- Slowly open flowmeter until pressure stabilizes at 30cm. H2O setting. (This determines the magnitude of the leak. If leak rate is greater than 300ml/min; proceed to step (G).)
- Refer to “What if machine leaks?
- Replace reservoir bag. Repeat step (B) and steps (D) through (F). This will determine the integrity of breathing bag.
- Open APL Valve at end of Leak Test Procedure by turning knob counter clockwise.
What if Machine Leaks?
- Breathing Bag – If leak occurs, replace.
- Breathing Circuit – Install new breathing circuit or obstruct inhalation / exhalation openings to determine if leak originates from breathing circuit.
- Vaporizer Fittings – Verify fittings and tubing are securely attached.
- Canister Gaskets – Check for loose absorbent grains between canister housing gaskets.
- Verify Canister is seated properly.
- Safety Valves – Remove valve and obstruct opening to determine if leak originates from negative pressure relief valve. Check the o-ring under valve for damage.
- APL Valve – Remove valve and obstruct opening to determine if leak originates from APL valve. Check the o-ring under valve for damage.
- Occlusion Valve – Remove valve and obstruct opening to determine if leak originates from Occlusion valve. Check the o-ring, diaphragm and back up ring on valve for damage.
- O-Rings under chrome retaining rings. Check the o-rings for damage.
