The HELiOS Personal Oxygen System is one of the smallest, lightest, and longest lasting portable systems available. It provides the long-term oxygen patient with the freedom to get out and go. Patients can return to a more active lifestyle without the encumbrance of bulky, heavy equipment and the bother of frequent refilling associated with traditional oxygen therapy systems. The H300 portable unit weighs a mere 3.6 pounds filled and has duration of use of 8-10 hours at a setting of 2. Refills from the HELiOS reservoir take a quick 40 seconds. The HELiOS portable unit operates in a variety of positions…safely and reliably. The HELiOS Personal Oxygen System gives home care companies the ability to cost effectively provide a better, friendlier system that breaks down the barriers to effective long-term oxygen therapy. Due to the system's efficiency, home care dealers can streamline liquid oxygen deliveries to as few as 8 per year.
