The HELiOS^® Personal Oxygen System has two key components:

• The HELiOS Plus^™ (H300) Portable Oxygen Unit
• The HELiOS Home Liquid Oxygen Reservoir

HELiOS Plus Portable Oxygen Unit
The portable unit has a built-in conserving device allowing oxygen to only be delivered when you take in a breath; it stops when you breathe out. The result: less waste allows oxygen supplies to last longer between refills. No batteries are required. <specs>

HELiOS Home Liquid Oxygen Reservoir
The HELiOS home reservoir stores the liquid oxygen for the HELiOS portable unit. The home reservoir, which is usually filled on a monthly basis by your dealer, is quiet, easy to operate and safe (when used as directed). You can also receive oxygen directly from the reservoir (via the CAIRE Inc.^® Flow Control valve or OxiClip^® Personal Oxygen Conserver) when you are not using the portable unit. This is convenient for restful time at home or for sleeping. Its quiet operation won’t disturb your sleep. <specs>

HELiOS System Safety
The HELiOS system has been thoroughly tested by CAIRE Inc. and cleared for use by the Food and Drug Administration (FDA). It is safe when used as directed.

FACT: Liquid oxygen is stored under far less pressure than compressed gas cylinders (22 psi for the HELiOS system vs. 2,000 psi for standard compressed gas cylinders). The pressure inside a HELiOS Portable Unit is similar to that of a bicycle tire!

Comparing HELiOS to Other Oxygen Systems
Don’t be fooled by other portable oxygen systems. No other system this small and light lasts so long. Plus HELiOS uses no batteries, so you don’t have to worry about running out of power. The chart below shows how HELiOS compares to other types of oxygen systems.
