and environmentally friendly materials,
pressurized with clean air that has been
filtered through multiple times. The pressure
in the cabin is adjustable from 1.1 to 1.5 ATA.
This product is foldable and portable, safe to
use, reliable, and easy to operate without third
party assistance.

PRECAUTIONS AND WARNINGS
• Please read the instructions carefully before using the device.
• Use a dedicated power outlet for the cord. Make sure that the power plug is fully
connected and not loose. Do not pull or twist the power cord with force
• Do not use the device in wet or humid conditions. The indoor temperature should be
maintained below 24°C and humidity below 50%.
• When cleaning or servicing the device, unplug the power wire.
• Stop using the device in case of any uncomfort.
• If an abnormal smell occurs during use, turn off the power and pull out the plug.
• Do not attempt to disassemble the machine or make modifications.
• Children can only use this product under adult supervision.
• Do not place heavy objects on top of the machine
• Do not touch electrical components with wet hands.
• Do not open the inner or outer zippers during use or before the chamber has depressurized
to 0kPa.
BEFORE FIRST USE:
• Test an empty chamber first to make sure that the device is operating normally.
• If the equipment is operating abnormally, please do not use it and contact support.
• When using the device for the first time, people can feel uncomfort in the ears, which
is normal. Swallowing saliva or yawning can help adapt to the change in pressure, just as
one would do during a plane takeoff. This is a normal phenomenon caused by increased
pressureand should disappear once the pressure in the chamber has stabilized at 35-40kPa.
After several times of use, this phenomenon will gradually disappear.
IN CASE OF AN EMERGENCY OR WHEN THE MANUAL PRESSURE REDUCING VALVE FAILS
TO WORK NORMALLY:
• Please press the emergency pressure reducing valve to relieve the pressure. When the
pressure reaches 0 kPa, open the zipper and exit the cabin. Do not open the zippers by force
during use or when the pressure relief is not completed.
CONTRAINDICATIONS
Whenever unsure about any listed or other potential contraindications, please make sure that
the client consults their doctor or seeks medical advice from the treating medical professional
before administering any treatments.
Below are some of the possible contraindications:
• Infectious diseases and other serious illnesses
• Open cuts or wounds
• Pregnancy
• Intoxication
• Chest or lung diseases, a severe cold
• Use of pacemakers
• Use of heavy medications
• Untreated pneumothorax (pneumothorax)
• Chemotherapy drugs (adriamycin, cisplatin and bleomycin)
• Acute sinusitis (inflammation of the sinus cavity)
• Severe imbalanced asthma
• Claustrophobia

INTRODUCTION
TECHNICAL SUMMARY OF DEVICE FUNCTIONALITY
CTN OxyPro™ devices are non-medical mild pressure oxygen therapy (mHBOT) devices and
are intended to enhance overall well-being and recovery. The devices are produced in both soft
shell (PVC Vinyl) or steel construction. The devices are available in single-seater, 2/3 person and
four-seater. The information presented here applies to all CTN OxyPro™ models, regardless of
size or material of manufacture.
DESCRIPTION OF THE TREATMENT EVENT
During operation of the device, the internal pressure of the OxyPro™ is raised from normal sea
surface air pressure to slightly less than 0.5 atmospheres (ATA), which corresponds to a depth
of about 4-5 meters underwater. An increase in pressure below 0.5 ATA means that the OxyPro
device is not classified as a pressure vessel according to applicable EU laws and regulations and
is not subject to EU classification and inspection regulations for pressure vessels. The non-med-
ical oxygen concentrator attached to the device increases the oxygen concentration inside
the device from 21% to a maximum of 33% of normal indoor air. Due to this relatively modest
increase in oxygen content, phones, laptops, etc. can be used in OxyPro during its use. Unlike
medical high-pressure HBOT devices, which, in addition to higher pressure, breathe 100% pure
medical oxygen, which together make the chamber fire sensitive.
SUMMARY OF THE USE OF THE DEVICE AND MARKETING OF TREATMENTS
Because OxyPro devices are not medical devices, medical claims should not be used in connec-
tion with them or when marketing treatments made with them. The devices are designed and
intended for general well-being therapy, and although breathing oxygen-rich air in a low-pres-
sure space has been proven to be beneficial for the client and refreshing and restorative in
various ways, not enough medical studies have been conducted on mHBOT treatments. Due to
the modest increase in pressure and oxygen levels compared to normal indoor air, CTN Oxy-
Pro™ is safe and easy to use. Nevertheless, in commercial use, it is recommended that staff be
present and the client monitored throughout the treatment to ensure that the client’s treat-
ment experience is pleasant and that treatment can be interrupted immediately if the client so
wishes.

PVHO-1 and NFPA 99 certified
May have a hard or soft shell. There are no sepa-
rately set standards for materials
Authorisation requirements
HBOT chambers require medical permission mHBOT chambers do not require medical permis-
sion
Classification and certification in the USA and EU
Class IIb medical device Not classified as a medical device
Fire extinguishing system
HBOT chambers are equipped with an effective
fire mist and water extinguishing system (HSFS)
as a mandatory feature
There is no need for a fire extinguishing system in
mHBOT chambers
Duration of treatment
Most often from 120 to 150 minutes 60 - 90 minutes
Site requirements
HBOT chambers can only be used in authorized
hospitals or medical clinics
mHBOT devices are often used in beauty salons,
gyms, various wellness clinics and home use
Medical examinations
More than 300 published medical studies proving
the effectiveness of treatment in HBOT chambers
The number of studies demonstrating the effec-
tiveness of medical treatment in mHBOT devices
is limited
Protection against voltage drops
A system of protection against voltage fluctua-
tions or drops in electrical voltage is mandatory
mHBOT chambers do not have mandatory protec-
tion against voltage fluctuations or drops
Medical recognition
The FDA approved 14 different diseases, the
European Committee of Hyperbaric Medicine
(ECHM) approved more than 30 different diseas-
es, the Society of Hyperbaric and Underwater
Medicine (UHMS) approved 14 different diseases,
the Society approved the European Baromedical
Association (EUBS)
The FDA and the Underwater and Hyperbaric
Medicine Society (UHMS) recommend one dis-
ease: acute altitude sickness (AMS) and its asso-
ciated mild symptoms. It has not been approved
or recommended by the European Committee of
Hyperbaric Medicine (ECHM). It is not approved or
recommended by the European Baromedical
Association (EUBS)
