Post-Valve Cylinder
This manual provides information necessary to operate the EVOLUTION OM-900 electronic oxygen conserver.
This conserver can be used with CGA 870 post-valve cylinder [see Fig. A] at home or away from home to
provide your specificoxygen requirements. It requires two (2) 1.5 volt AA alkaline batteries for operation.
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 savingis possible. Additionally, the oxygen available during the
very first part of inhalation contributes most to meeting oxygen needs.
The OM-900 electronic oxygen conserver takes advantage of these facts to
provide maximum efficiency in the delivery of oxygen. Thisdevice is
designed to be an integral component of a lightweight, long-lasting
supplemental ambulatory oxygen system.
