1Description
The anesthaesia machine NarkoVet is a semi-closed loop system with partial rebreathing.
The device is suitable for anesthaesia of small animals up to a body weight of 80 kg.
For animals up to 15 kg it is recommended to use the included pendulum system (Bain Circuit).
Further advantages of NarkoVet are:
-Respiratory valves that are large and easy to see
-A soda lime container that is easy to refill and install with a capacity up to 10 hours of anesthesia
-Pipes for fresh gas that are easy to adapt and which can also be used for anesthaesia boxes
-Flow meter that is easy to adjust and read with a gas flow from 0.2 to 4.2 l/min
-Flush button for the oxygen bypass

3Startup Procedure
Connect the oxygen supply line (5) to the oxygen supply.
This can be done either through:
-Oxygen cylinder and pressure reducer (Part No. 212705 or 21270501)
-Oxygen concentrator (Part No. 213175 + 213160)
-Air connector (piped oxygen) (Part No. 212503)
The input pressure should be about 3 bar. When using an oxygen concentrator the inlet pressure is lower due to the
type of construction. Thus, the filling time of the breathing bag is extended when operating the flush button
(oxygen bypass (2)). The flow meter, however, always displays the correct oxygen flow.

(not included in the delivery)
Fill the evaporator with Isoflurane.
The procedure is shown on the evaporator.
1. Screw the Isoflurane key fill adapter onto bottle (Art. No. 213246)
2. Untighten the screw on the side of the safety filling device, remove the sealing block, introduce the safety filler
into the filling tunnel and tighten screw.
3. Turn the black filling screw to the 12 clock position.
4. Fill the evaporator up to the maximum filling mark.
5. Set the black filling screw on 3 clock position
6. Remove the key fill adapter and insert sealing block and turn the screw very tightly.
7. In older evaporators this may be impossible due to the lack of ventilation. In this case loosen the bottle from the
filler, so that air bubbles ascend in the bottle so that the anesthetic agent runs into the evaporator.
8. A strong Isoflurane odour deriving during the filling, it indicates a worn out seal plate, which must be changed.

Filling the soda lime
Turn the lock lever of the absorbent container (11) counterclockwise. Remove the soda lime.
Fill the container with soda lime.
The max. filling line must not be exceeded.
Insert the container and lock it by turning the lock lever clockwise.
Plug in the patient circuit and the breathing bag.
Connect an exhaust pipe to the pressure relief valve.

4Operation of the Pendulum System (Bain Circuit)
The Bain Circuit supplements the basic unit perfectly for anesthaesia of smaller patients. It contains no breathing
valves. The anesthetic gas is transported directly from the evaporator via the fresh gas pipe to the patient. This
ensures quicker wash-in and wash-out even with a smaller minute volume.
The exhalation takes place into the breathing bag, and in the case of overpressure air is transferred via the open
valve in the exhaust pipe.
The pressure relief valve should always be fully opened during spontaneous breathing (against clockwise direction).
A re-breathing of exhaled carbon dioxide is prevented by the influx of fresh gas into the breathing bag (open
system).
Recommended quantity of fresh gas for wash-in: 800 ml - 1000 ml/min
Concentration of Isoflurane: 2.5% - 3.5%
Maintenance values as required, but at least 500 ml/min fresh gas (depending on evaporator).
Please pay attention to the correct assembly of the anesthaesia system, as shown in the picture above.

5Preparing the Device before Anesthaesia
Check the oxygen supply (pressure and access to sufficient oxygen).
Connect patient tube and breathing bag to the anesthesia machine and close the pressure relief valve.
Keep your thumb on the patient's end of the tube and inflate the breathing bag via the
Oxygen bypass until the breathing bag is bulging. The anesthaetic system is sufficiently tight once a fresh gas flow
of less than 200 ml is needed to maintain this inner pressure.
Now check the function of the overpressure valve by fully opening it very slowly.
If the internal pressure is not adequately maintained, there is a leak in the system which has to be found before
using the anaesthetic machine.
Check the anesthetic level of the Evaporator.
A common leakage location of the evaporator is the filling tunnel with the seal plate. The rubber rings can be brittle
and disintegrate so that the seal is no longer functioning. As well an insufficiently tightened sealing block may
cause anesthetic loss.
In general, due to the built in pressure compensation of the evaporator a loss of anesthetic agent up to 0.5 cm3per
day can be expected.
6Anaesthetic Procedure
Typically in a semi-closed system a fresh gas flow of 2 l/min at a selected concentration of 3.0 vol%at the
evaporator is sufficient for a quick wash-in. The depth of anesthaesia needs to be monitored and the concentration
to be changed if necessary.
To maintain the anaesthesia, generally it is sufficient to follow the guidelines of the MAC-values + 15% inspiratory
add as per the package leaflet at minimum 500 ml/min oxygen inflow (watch status of anaesthesia and breathing
continuously).
The MAC values are
Dog: 1.28%
Cat: 1.63%
Birds: 1.45%
Small mammals: 1.34%
Rat: 2.40%
Pay attention to the decreased wash-in and wash-out times of an Isoflurane-only anesthaesia in comparison to
halothane or mixed anesthaesia. In general, the evaporator should be closed just at the time of the final suture
(5 min before the intended end of the OP).

7Cleaning and Maintenance of Anesthaesia Equipment
Remove breathing bag, the patient tube and other tubes from the device and dry them (if necessary, clean with
detergent).
Unscrew the lids of the breathing valves and let them dry too.
If you remove the valve plates, it will speed up the drying process. But please make sure to insert these plates again
before the next anaesthetic, otherwise proper gas exchange is no longer guaranteed.
Approximately every 10 hours, please change the absorbent, even if the indicator change did not take place.
Please check every 20 hours of anesthaesia all exposed sealing rings for wear and tear and lubricate with silicon
vaseline.
Once a year, the evaporator should be subjected to a technical inspection to ensure proper functioning. In this case,
please contact the EICKEMEYER® Customer Service.
Precautions for handling Isoflurane:
Isoflurane is a highly volatile anaesthetic. Therefore, when used in closed spaces ensure that a suction tube is
properly connected to the pressure relief valve or the Bain Circuit. If ventilation of gases is not possible into the
open air, we recommend an anesthetic gas filter (Art. No. 213485).
