What is
CONTRAfluranTM
The CONTRAfluran™ canister captures all modern fluorinated gases.1However, from a manufacturing/reprocessing perspective, it is recommended that the CONTRAfluran™ canister is used only to capture
desflurane and/or sevoflurane. Should the CONTRAfluran™ canister be used to capture isoflurane, it is recommended that is is captured in a dedicated canister which is separate from that used to capture
desflurane and/or sevoflurane. For complete installation support, please contact your Baxter sales representative.

Section 1) Installation
1. Which gases does the CONTRAfluranTM canister capture?
The CONTRAfluranTM canister captures all fluorinated gases.1However, for practical purposes, it is recommended that this is used with desflurane
and sevoflurane, since the capturing of isoflurane will delay the desorption process of desflurane and sevoflurane from the canister.
2. What are the components of starter kit?
The starter kit includes the following components:
3. Who is responsible for the system installation and return of used canisters?
The Baxter sales team will support customers with installing the CONTRAfluranTM Gas Capture System. For returning used canisters,
the hospital will need to inform/call Baxter customer service to discuss their return request.
4. What voltage does the unit/power cord use?
It is designed for an operating voltage of 100V–240 V AC/47–63 Hz.1
5. If CONTRAfluranTM is not classified as a medical device, what is it categorised as?
The CONTRAfluranTM Gas Capture System falls under Class 1 of medical devices.1The devices in this category are mostly exempt from registration

Section 1) Installation
9. Is the device MRI compatible?
The SENSOfluranTM Sensor Unit should not be used in the vicinity of an MRI scanner. The strong, static magnetic field of the MRI scanner may cause unwanted
movement, including dangerous projectile motion of the device. The radiofrequency energy and magnetic fields that change with time may also cause heating
of the metallic housing, which could lead to burns.
However, the CONTRAfluranTM canister is non-metallic and could be used alone in the vicinity of an MRI scanner if connected to a hose that does not contain
any metallic components (e.g. reinforcing ribs).
To ensure the safe use of CONTRAfluranTM inside an MRI room, hospital staff should conduct a thorough check of the hose and other accessories connected
to the CONTRAfluranTM canister to confirm that there are no metallic materials inside the safety zone defined by the MRI scanner manufacturer.
10. Is it device latex free?
Yes, the SENSOfluran™ unit is latex free.
11. Can we purchase circuit boards separately?
Yes, there is a separate part number for ordering circuit boards.1This is: ZEO000042.1
12. I believe the AGSS needs to be turned off when using CONTRAfluranTM with an anaesthesia machine.
Do we have detailed instructions on how this is done? Or preferably, will the hospital or manufacturer
representatives do this?
Anaesthesia machines need to be configured for PASSIVE gas scavenging. The Hospital Biomedical engineers/qualified technicians will be able to make changes
to the anaesthesia machine AGSS. To make the mechanical changes required to use the CONTRAfluranTM unit with a Dräger/GE/Maquet anaesthesia machine, the
hospital should contact their local anaesthesia machine sales representative.
For hospitals that do not want to switch off their AGSS, we have developed SENSOfluranTM PLUS. This can be connected to the AGSS, but the anaesthesia machine
still needs to be changed to passive mode. SENSOFluranTM PLUS also provides a solution for hospitals using nitrous oxide.
Please note, nitrous oxide must ONLY be used when the hospital’s AGSS is connected to SENSOFluranTM PLUS.

13. How do we know that we can switch off the AGSS and it will still be safe for staff?
The CONTRAfluranTM unit captures 99% of a patient’s exhaled anaesthetic gas in the operating theatre.2ZeoSys conducted testing that showed how gas escape
was minimal. Hospitals should exercise caution when setting up their inhaled anaesthetic circuits to ensure that there are no leaks elsewhere in the system.
Only gas that passes through the CONTRAfluranTM filter will be adsorbed. There is a test protocol available for hospitals to test this themselves if they choose to.
In the event that hospital personnel smell any anesthetic gas when using the CONTRAfluranTM system, please check all connections to determine the source.
14. What are the mounting options available?
The bracket on the SENSOfluranTM unit seems to work for all anaesthesia machines seen to date. It can rotate 90 degrees to accommodate either a vertical
or horizontal bracket on the back of all anaesthesia machines. This allows SENSOfluranTM to be operated either with a view to the front or to the back of the
anaesthesia machine.
The images below demonstrate how the SENSOfluranTM unit can be installed on different anaesthesia machines
15. When we try to pull off the red cap, the lid also comes off quite easily. How do we stop this?
Hold the white lid down with one hand while removing the red cap. Ensure the lid is firmly attached after removing the red cap and hose connection.

16. Will there be any risks (such as activated carbon spilling on the floor or captured gas leakage)
if the container falls on the floor and lid comes off?
No, there is no risk. In the event of a spillage, collect and place the contents in a Ziploc®bag and place it in the normal waste receptacle.
17. Does this system fit all anaesthesia machines?
Currently the Zeosys gas capturing technology can function with any anaesthesia machine that can be configured for passive scavenging mode. Dräger, GE and
machines from other manufacturers are designed to provide this scavenging configuration. There are a few machines, such as Dräger Atlan and Getinge Flow,
that do not have the ability to be configured to passive mode. In case of doubt, please consult the manufacturer of the anaesthesia machine.

FAQs about CONTRAfluran™ and SENSOfluran™
Section 2) During surgery
1. Can one canister capture a combination of sevoflurane and desflurane?
Yes, one canister can capture a mixture of the two gases.
2. Do the inhalational anesthetic gases need to be manufactured by Baxter, or can the canisters capture gases regardless of
the manufacturer?
The canisters are designed to capture sevoflurane or desflurane1regardless of the manufacturer.
3. How long does it take to fill one canister?
The time taken to fill one canister will vary depending on the FGF (fresh gas flow) rate and concentration (similar to how the length of time a container of
sevoflurane or desflurane lasts seems to vary). However, on average, the canister lasts ~3 days, but this will vary significantly depending on the circumstances.
Regardless, a CONTRAfluranTM filter is likely to accommodate a full canister of inhalational anaesthetic gas.
4. Can the canister be changed mid-surgery?
Yes, the amount of gas released from the hose while changing the canister is not significant. The new canister should be readily accessible
so that the anaesthesia gas hose can be disconnected quickly from the used canister and attached to the new one.
5. Does the SENSOfluranTM Sensor Unit work by weighing the canister or does it physically analyse the gas flow?
The sensor unit does not work by weighing the canister. Instead, there is a gas sensor built into the bottom of the sensor unit. The gas detector analyses the air
that flows out of the canister through a small hole in the bottom of the canister. The gas sensor can detect different types of anaesthetic gases.
• Please note, SENSOfluranTM does not detect nitrous oxide and CONTRAfluranTM does not capture nitrous oxide1
6. Will the CONTRAfluranTM canister capture all gases (including nitrous oxide and isoflurane) or just sevoflurane and desflurane?
The technology is currently designed to capture only fluorinated halocarbon inhaled anaesthetic gases (more specifically, sevoflurane and desflurane)
from the expired air of a patient.1The system can capture isoflurane, but Baxter will not collect the canisters filled with isoflurane. It does not capture nitrous oxide.
