This manual provides information necessary to safely operate the EVOLUTIONTM electronic
oxygen conserver with built-in regulator. The intended purpose of the EVOLUTIONTM conserver is
to provide a regulated flow of medical oxygen from portable cylinders to patients with therapeutic
oxygen needs at their prescribed flow rates.
The EVOLUTIONTM conserver can be used with any
Pin Index valve cylinder (see Fig. A) at home or away
from home to provide your specific medical 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:

The EVOLUTIONTM electronic conserver is designed for use as part of a portable ambulatory
medical 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 high-pressure regulator and an oxygen
conserver and is capable of delivering a precise amount of supplemental medical oxygen at
the optimal point in the breathing cycle. Operationally, the EVOLUTIONTM conserver greatly
eliminating unnecessary medical 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.

Prior to beginning therapy, patients must be given instruction by qualified personnel on how to
use the unit.

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