The HELiOS system provides the long-term oxygen patient with the freedom to do
just about anything, all day long. Patients can return to a more active
lifestyle without the encumbrance of bulky, heavy equipment and the bother of
frequent refilling. The product weighs a mere 3.4 pounds filled and is so small
that it is hardly noticeable. Duration of use is 10 hours at a flow setting of
2. Refills from the HELiOS reservoir take 40 seconds and are less frequent.
