HELiOS 300 & 800
Introduction
A liquid oxygen system is designed to provide sup-
plementary oxygen as prescribed by a physician.
Your liquid oxygen system includes a HELiOS
portable unit and a stationary reservoir. The res-
ervoir is the larger container that is used to fill your
HELiOS portable. This user manual contains only
the instructions for using the HELiOS portable. Re-
fer to the user manual supplied with your reservoir
unit for information on its operation.
HELiOS portable liquid oxygen units are designed
to be an ambulatory source of oxygen for an
extended period of time. They are filled with liquid
oxygen from a reservoir unit with a compatible fill
connector. HELiOS portables are available in two
different sizes.
The H300 Plus is primarily a conserving device
and holds 0.38 Liters of liquid oxygen. It provides
demand (pulse) flow settings 1-4, and limited low
dose continuous flow settings at 0.75 LPM and
below only.
The H850 Marathon can be used as a conserving
or continuous flow device and holds 0.84 liters of
liquid oxygen. It provides continuous flow from 1-6
LPM and demand flow on settings of 1-4.
