  • Helios Portable Oxygen System and Reservoir

    Small, lightweight, and long-lasting, encourages an active lifestyle for long-term oxygen therapy patients. No tubes, heavy canisters or batteries are required. The system is also extremely economical. Its pneumatic oxygen conserving device gives it a conservation ratio over continuous flow oxygen of approximately 4:1. This provides up to 10 hours of use at a setting of 2. The portable unit can be refilled in about 40 seconds from the home reservoir, which typically lasts four to six weeks between refills.

  • Hepatitis C HCV

    An inflammation of the liver causing soreness and swelling. It is the most common chronic blood-borne infection in the United States. The hepatitis C virus usually is transmitted through contact with infected blood, most commonly by sharing needles during intravenous drug use, or getting a blood transfusion before 1992. Hepatitis C also may be spread through unprotected sexual intercourse, but this is uncommon. Most people don't feel sick when they are first infected with hepatitis C. Instead, the virus stays in their liver and causes chronic liver inflammation.
