1-1 INTRODUCTION
The MOST 20-2B of P/N 793080-002 references the fact
that the cylinder liner is made of brass and is designated
for 2,250 psi fill pressure.
1-1.1 Indications For Use
The Mobile Oxygen Storage Tank (MOST) is intended to
provide USP 93% (+7%/-3%) oxygen at 50psig nominal
pressure for supplemental oxygen use only.
1-1.2 Mobile Oxygen Storage Tank (MOST)
The MOST was initially designed to meet the demands of
the mobile medical oxygen delivery/transport. The
availability of transportable medical oxygen is a prime
factor in aiding trauma patients.
Initially, oxygen demand was met by use of high-pressure
steel oxygen cylinders. Cylinders satisfied the requirement
for oxygen but created unacceptable logistical burdens
associated with transportation, refill, and storage.
The introduction of the liquid oxygen based systems
reduced the size and weight of the oxygen delivery
equipment and replaced many applications previously
filled with the oxygen cylinders, but created additional
problems. Liquid oxygen cannot be stored. It must remain
below -297°F to stay in a liquid state and it rapidly boils
off losing as much as 5% per day. Transportation over long
distance results in a high percentage of loss.
There is an urgent need for an oxygen transportation
system that can be stored and stockpiled, ready for
immediate use, transported with the medical unit and
totally self sufficient for as long as required. It also has to
be easy to
operate dependable and as small and light as
possible. The Mobile Oxygen Storage Tank (MOST) has
been developed to address these requirements.
1-2 SYSTEM OVERVIEW
The Mobile Oxygen Storage Tank (MOST) is a storage and
distribution system consisting of lightweight, high strength,
high-pressure composite wound brass lined cylinders secured
within a rugged case. The MOST contains 10,000 liters of
oxygen when filled to 2,250 psig. The MOST has a maximum
flow capability of 150 lpm at 50 psig (50 lpm per Oxygen
Output fitting).
The operating panel on the end of the unit contains the
following:
● One high pressure Oxygen Input fitting is
provided for filling the MOST from various high-
pressure sources.
● A Cylinder Contents Gauge indicates the cylinder
pressure (both cylinders combined).
● Three Oxygen Output fittings are provided to
attach the Oxygen Conducting Delivery Hose(s)
that supply oxygen to the patients.
● An Output Pressure Gauge indicates the output
pressure of the oxygen.
A Cylinder Contents Gauge (P1-1) is provided on the long
side of the case. This pressure gauge is marked in liters
indicating the liters of oxygen remaining in the MOST. It
is placed in this position to allow reading of the remaining
capacity from either the side or the end of the unit. When
filled to 2,250 psig, the MOST contains 10,000 liters of
oxygen (See Fig 1-1).
