1 Safety Information
Overview
This section contains important safety information
related to general use of the HELiOS MARATHON™
H850 portable oxygen system, which consists of the
portable oxygen unit and a liquid oxygen reservoir.
Other important safety information appears with
its relevant material throughout the manual. Read
all text surrounding precautionary information.
Before use, carefully read this manual and all
precautionary information in boldface type, as well
as the product specifications.
Warnings
Warnings are identified by the WARNING symbol
shown above or other relevant symbols, as shown
on the following pages.
Warnings alert the user to potential serious
outcomes (death, injury, or adverse events) to the
patient or user.
WARNING
Oxygen supplied from this equipment is for
supplemental use and is not intended to be life
supporting or life sustaining. This equipment is not
intended for use by patients who would suffer

Safety Information
2 HELiOS MarathonTM H850 Portable Oxygen Unit Home Use Guide
immediate, permanent, or serious health
consequences as a result of an interruption in the
oxygen supply.
WARNING
Where the prescribing health care professional has
determined that an interruption in the supply of
oxygen, for any reason, may have serious
consequences to the user, an alternate source of
oxygen should be available for immediate use.
WARNING
Do not smoke near this equipment. Keep cigarettes
or burning tobacco away from the area where
equipment is operated.
WARNING
Keep flammable materials away from this
equipment. Oils, grease, including facial creams and
petroleum jelly, ignite easily and may burn rapidly in
the presence of oxygen. Never lubricate any part of
this equipment.
WARNING
Do not touch liquid oxygen or parts that have been
in contact with liquid oxygen. Liquid oxygen is
extremely cold (-297 °F / -183 °C). When touched,
liquid oxygen, or parts of the equipment that have
been carrying liquid oxygen, can freeze skin and
body tissue.
WARNING
At higher flow rates, the exterior of the portable may
become extremely cold. Avoid skin contact. Do not
touch frosted parts.
WARNING
Always keep the reservoir in an upright position.

Safety Information
HELiOS MarathonTM H850 Portable Oxygen Unit Home Use Guide 3
WARNING
Always keep the H850 portable oxygen unit in one of
the following positions: upright, flat on its back or
angled at some position in between.
WARNING
When transporting the H850 portable oxygen unit,
position the H850 horizontally, flat side down, to
ensure it does not tip over. Tipping over and falling
off a transport surface could damage the H850
portable oxygen unit or cause personal injury.
WARNING
Keep this equipment away from electrical
appliances. Use and store reservoir and H850
portable oxygen unit at least five feet from electrical
appliances that may cause heat or sparks.
WARNING
Keep oxygen equipment away from open flames.
Use and store reservoir and H850 portable oxygen
unit at least five feet away from equipment such as
furnaces, water heaters, and stoves that may contain
open flames.
WARNING
Keep equipment in a well-ventilated area at all
times. The reservoir and H850 portable oxygen unit
periodically release small amounts of oxygen gas
that must be ventilated to prevent buildup. Do not
store liquid oxygen equipment in a closet, car trunk,
or other confined area. Do not place blankets,
draperies, or other fabrics over equipment.
WARNING
Do not carry the H850 portable oxygen unit under
your clothing. The reservoir and H850 portable
oxygen unit normally vent oxygen. Wearing a H850

Safety Information
4 HELiOS MarathonTM H850 Portable Oxygen Unit Home Use Guide
portable oxygen unit under clothing may saturate
fabrics with oxygen and cause them to burn rapidly
if exposed to sparks or flame. It may take several
hours for oxygen levels in fabric to return to normal.
WARNING
Keep dry.
WARNING
Never tamper with the equipment. Doing so could
create a hazardous condition and possibly cause the
equipment to work improperly.
WARNING
As with all medical equipment, carefully route
patient tubing to reduce the possibility of patient
entanglement or strangulation. Always keep tubing
or oxygen supply line away from path of walking to
avoid potential trip or fall.
WARNING
Use only with recommended supply line. Connecting
the H850 portable oxygen unit to a wrong gas
source could cause inhalation of hazardous
substances.
WARNING
Do not open the vent valve during non-fill use, or
put it into any position other than the closed,
upright, or vertical position.

2 Introduction
WARNING
At higher flow rates, the exterior of the portable may
become extremely cold. Avoid skin contact. Do not
touch frosted parts.
Your HELiOS MARATHON™H850 portable oxygen unit
is designed to store and deliver oxygen at a
prescribed rate. The HELiOS Marathon H850
portable oxygen system is LATEX-FREE and consists
of the portable oxygen unit and a reservoir.
The portable oxygen unit delivers continuous flow
oxygen, based on the selected flow setting. See
Breathing from a Portable Oxygen Unit, page 23, for
details on setting flow rates.
Caution
Use the nose cannula specified by your health care
provider or caregiver appropriate to the situation (rest,
exercise, sleep). Differences in nasal cannula design may
vary the ability to trigger the conserving device used in
the H850 portable oxygen unit.
Breathe through your nose and not your mouth,
since the HELiOS Marathon H850 portable oxygen
unit is designed to sense nasal cannula breathing.
Breathe only the prescribed oxygen rate from the
portable oxygen unit. There are two different
means of obtaining the oxygen you need using the
HELiOS Marathon H850 portable oxygen unit.
1. Portable Mode—Fill the portable with liquid
oxygen and move freely about your home or
leave your home for extended periods. The
HELiOS Marathon H850 portable oxygen unit

Introduction
10 HELiOS MarathonTM H850 Portable Oxygen Unit Home Use Guide
was designed to maximize freedom of
movement. Fill the portable with liquid oxygen
from the reservoir every day to use as far from
the reservoir as desired.
2. Tandem Mode—You can connect the portable
to the reservoir. See Connecting the Portable
Oxygen Unit to the HELiOS Reservoir, page 31.
When at home and not moving about, connect
the portable oxygen unit to your reservoir with
an oxygen supply line. When the HELiOS
Marathon H850 portable oxygen unit is
connected to a HELiOS reservoir in this manner,
the reservoir supplies oxygen, rather than the
portable oxygen unit.
Caution
The oxygen supply line should only be used when the
H850 flow control knob is set to a demand mode
setting.

Introduction
HELiOS MarathonTM H850 Portable Oxygen Unit Home Use Guide 11
Have your oxygen supplier or home care provider
refill your reservoir periodically, depending on your
oxygen use rate.

from the portable oxygen unit. It must be a dual-lumen cannula for
the portable oxygen unit to function properly.

oxygen flow with each breath.
4 Liquid Oxygen Fill Connector—Use connector located on the
bottom of the unit for attaching H850 portable oxygen unit to
