This manual provides the information necessary to operate the EVOLUTIONTM electronic oxygen
conserver with built-in regulator in accordance with a physician’s prescription.
The EVOLUTIONTM conserver can be used with any
CGA 870 post-valve cylinder (see Fig. A) at home
or away from home to provide your specific oxygen
requirements. It requires two (2) 1.5 volt AA alkaline
batteries for operation.
Statements in this manual preceded by the following
words are of special significance:
WARNING!
Indicates there is a possibility of injury to you or others.
CAUTION!
Indicates there is a possibility of damage to the device or to other property.
☛
NOTE
Indicates points of particular interest or emphasis that allow for more efficient and convenient
operation of the equipment.

IMPORTANT SAFETY RULES & PRECAUTIONS
Read this instruction manual carefully to ensure your complete understanding before operating your
EVOLUTIONTM electronic conserver. This manual is part of the unit and must be available at all times.
Use the unit for the designated purpose only (see “Purpose” on page 7).
For your own safety and that of your patients, please observe the following points:
OPERATING THE UNIT
WARNING!
Failure to observe the following warnings may result in damage to the unit or injury to life or
limb:
• Smoking near oxygen equipment is strictly prohibited. While using your EVOLUTIONTM conserver, your
clothes may come into contact with oxygen-enriched air, making your clothes more flammable. This
also applies for a time after use, until the increased oxygen concentration has escaped from your
clothing. For this reason, you must keep cigarettes, matches, burning tobacco and open flames,
such as lighted candles or fireplaces, away from the area where the system is being stored or
operated.
• Avoid the creation of any spark, such as static electricity caused by any type of friction, near the
oxygen equipment.
☛
NOTE: Oxygen will not burn; however, it does vigorously accelerate the burning of any flammable material.
• Cannula tubing is a disposable accessory that should be replaced periodically following normal
usage. Continue reuse of cannula tubing may cause contamination which may lead to respiratory
distress. Disposable tubing should be disposed of in accordance with local ordinances and/or
regulations for disposal. Replacements are available through your homecare provider. (OC-401S,
case of fifty (50) 4 ft [1.52m] cannulas or equivalent).

IMPORTANT SAFETY RULES & PRECAUTIONS
WARNING! (Cont.)
Please remember that this is for your own safety!
• Keep all parts free of oil and grease. Hydrocarbon compounds such as oil, grease, petroleum-
based products, cleaning agents containing alcohol, hand cream or adhesive bandages can
cause explosive reactions if they come into contact with highly compressed oxygen. Please
wash and dry your hands properly prior to operating your oxygen equipment.
• Never use aerosol sprays near the oxygen equipment.
• Do not use in the presence of flammable anesthetic mixture.
• Keep your oxygen equipment at least 5 ft. (1.5 m) away from any electrical appliance.
• Be sure to turn off the oxygen supply by closing the cylinder valve when not in use.
• Do not use cannula tubing that is longer than 7 ft. (2.13 m).
• Do not use a mask or pediatric or other low-flow cannula tubing when operating the unit.
• Do not use the EVOLUTIONTM conserver as a handle for carrying your oxygen cylinder.
CAUTION!
• To prevent the unit from overheating, do not place it near any heating devices and do not
expose it to direct sunlight. Do not expose the unit to extreme temperatures.
• Your EVOLUTIONTM conserver must not be immersed in liquid or cleaned with liquid agents.
Prevent water or other liquid substances from entering the unit.
• Protect your EVOLUTIONTM conserver from the cold and from continued exposure to water,
such as rain.
• Please observe the section “Hygienic Preparation” on page 16 in order to avoid infection or
bacterial contamination.
• Prevent dust or any small particles from entering the unit.
• Take care not to get entangled in the nasal cannula tube, which could impede movement and
lead to discomfort around the throat.
• Your EVOLUTIONconserver is protected against interference. To ensure safety of use,
however, do not use a mobile phone in the immediate vicinity of the unit.
5
CAUTION! (Cont.)
• Oxygen conserving systems only work reliably upon sufficiently strong inhalation. Therefore,
please observe the following:
• Do not use the EVOLUTIONTM at night or while sleeping;
• Do not use the EVOLUTIONTM for babies or children;
• Do not use the EVOLUTIONTM if you only breathe through your mouth.
• Do not use the EVOLUTIONTM if you breathe more than 40 times per minute.
• Closely observe the permissible ambient conditions listed in the “Technical Data” section on
pages 21-23. Failure to observe them may lead to a fire risk or damage to the unit.
• Tighten all screwed unions by hand only. Do not use a tool.
• Do not use the EVOLUTIONTM with a humidifier.
• Do not use if leaking or damaged.
• Always open the cylinder valve slowly.
• Be sure to carry extra AA-size alkaline batteries in the event they are needed.
☛
NOTE:
• Always ensure that your oxygen cylinder is sufficiently full. We recommend always keeping a full
spare cylinder in reserve.
• Oxygen supplied by this equipment is supplemental only and is not intended for life support applications.
ACCESSORIES/REPAIRS
CAUTION!
• Malfunctions and a lack of biocompatibility may result if third-party articles are used. Please bear
in mind that in these cases any guarantee entitlement and liability shall lapse where accessories
recommended in the instruction manual or original spare parts are not used.
• Servicing and repair work must only be carried out by the manufacturer (CHAD Therapeutics) or
by trained personnel. Refer repairs to authorized personnel.
Please contact your Home Care Provider if you have any questions.

IMPORTANT SAFETY RULES & PRECAUTIONS
INTRODUCTION
PURPOSE
The EVOLUTIONTM electronic conserver is designed for use as part of a portable ambulatory
oxygen system for the purpose of facilitating long-term oxygen therapy (LTOT). It provides
mobile LTOT patients with an extended operating time of their mobile system. The EVOLUTIONTM
conserver includes a combination of a low-pressure regulator and an oxygen conserver and
is capable of delivering a precise amount of supplemental oxygen at the optimal point in the
breathing cycle. Operationally, the EVOLUTIONTM conserver greatly increases efficiency in the
delivery of oxygen, maximizing the beneficial effects and eliminating unnecessary oxygen waste.
The EVOLUTIONTM is not suitable for use during sleep.
The EVOLUTIONTM is not suitable for children.
Use the unit exclusively for the purpose described above.
USER QUALIFICATION
Prior to beginning therapy, patients must be given instruction by qualified personnel on how to
use the unit.

FUNCTION
When we breathe, approximately one-third of the time is spent inhaling, and two-thirds exhaling.
As a result, oxygen delivered by continuous flow is wasted during exhalation. By eliminating
oxygen flow during exhalation, a two-thirds savings is possible. Additionally, the application
of the EVOLUTIONTM is based on the fact that only oxygen inhaled at the beginning of the
breath actually reaches the alveoli and is absorbed by the body. The oxygen inhaled during the
remainder of the breath is not used and is exhaled again. For this reason, the EVOLUTIONTM
only administers oxygen at the beginning of inhalation. This makes the oxygen source last
longer. The EVOLUTIONTM is designed to be an integral component of a lightweight, long-lasting
ambulatory system.
