  1. Artificial Oxygen Carriers By: Kyla Murray BME 281 Seminar, Section 1 November 28, 2012

  2. Artificial Oxygen Carriers are a type of red blood cell substitute Synthetic molecules that consist primarily of carbon and fluorine atoms Have the ability to dissolve significant quantities of oxygen and carbon dioxide Improve oxygen transport and oxygen unloading to the tissue Alternative to allogeneic* blood transfusions or to improve tissue oxygenation and function of organs with limited oxygen supply * Allogeneic meaning genetically different HBOC is a “Hemoglobin Based Oxygen Carrier” Must be approved by the FDA before clinical use because these substances are considered drugs What are AOC’s and HBOC’s?

  3. Late 1800’s, free hemoglobin solutions were administered Modern scientific attempts to replace human blood began in the early 1900’s HBOC’s were created in the 1930’s by Amberson Modified study by Chang in 1957 Companies with HBOC’S: HemAssist (Phase III Clinical Trials) Hemolink (Phase II Clinical Trials) OxyVita (Pre-Clinical Trials) History of AOC/HBOC

  4. Developed for 2 main purposes: Function as alternatives to blood transfusion (avoid, reduce, and delay transfusion of allogeneic blood) Improves the tissue oxygenators of organs with poor blood supply NOTE: It is a Red Blood Cell Substitute, not a complete replacement. The AOC is much smaller than a red blood cell, and can travel through smaller capillaries Uses of the AOC

  5. Benefits and Disadvantages of the AOC • Still going through intensive clinical trials, but plan to have/be: • Long circulation half-life • Long shelf life • Oxygen delivered to the tissues in need • Differing side effects (Flu-like symptoms or an increased risk in death/heart attack) • Reasonable cost

  6. Future of the AOC • Pass the clinical trials • Will be on the market • Less of a health risk • Health Care Coverage
