    OXYGEN DELIVERY TO TISSUES 1259 and keeping the intercapillary spacing close enough (3). depends largely on convective oxygen transport accomplished by the heart, lungs and blood [4]. 2 ) bear an indirect relationship to the actual driving forces for diffusive oxygen transport and for mitochondrial oxygen availability.Author: R. W. Samsel, P. T. Schumacker

Oxygen delivery to tissues.

    https://www.ncbi.nlm.nih.gov/pubmed/1804674
    A growing body of evidence suggest that tissue oxygen extraction may be impaired in adult respiratory distress syndrome (ARDS) and sepsis. In these syndromes the minimum oxygen delivery needed to maintain a normal oxygen uptake appears to be increased, as tissues become hypoxic despite high levels of delivery.Author: R. W. Samsel, P. T. Schumacker

    Aug 01, 2004 · Oxygen is carried in arterial blood dissolved in solution (<2% when breathing air) and combined with haemoglobin (>98% in air). Tissue hypoxia is a deficiency of oxygen at the tissue level; it may be caused by increased demand, decreased supply or abnormal cellular utilization.Author: S. A. McLellan, T. S. Walsh

    Oxygen delivery to the periphery depends on the oxygen content of blood and tissue blood flow. The oxygen content of blood has two components: oxygen bound to hemoglobin and oxygen dissolved in plasma. Oxygen bound to hemoglobin is generally the much greater contributor to oxygen content.

Increasing Oxygen in Tissues HowStuffWorks

    Blood doping is the practice of infusing whole blood into an athlete in order to increase oxygen delivery to the tissues. A similar effect can be achieved by training at high altitudes. An athlete who infuses his own blood may cause infection or cardiovascular problems because of the increased blood volume (high blood pressure, blood clots, heart failure and stroke).

    Most of the oxygen binds to hemoglobin in red blood cells, although a small amount dissolves into the plasma. The oxygen is then transported from the lungs to the peripheral tissues, where it is removed from the blood and used to fuel aerobic cellular metabolism.

ABC of oxygen: Oxygen transport—2. Tissue hypoxia

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1114253/
    Nov 14, 1998 · Oxygen delivery would be optimised by maintaining cardiac output and haemoglobin concentration and ensuring oxygen is released to tissues by manipulating the oxygen-haemoglobin dissociation curve. In contrast, prognosis in chronic obstructive pulmonary disease is improved by continuous oxygen to maintain the Pa o 2 above 8 kPa and the saturation over 90%.Author: R M Leach, D F Treacher

    https://academic.oup.com/bjaed/article/16/10/341/2288629
    May 17, 2016 · Global oxygen delivery, or oxygen dispatch, describes the total amount of oxygen delivered to the tissues each minute, and is a product of the cardiac output and arterial oxygen content. Oxygen diffuses from both the alveoli into the pulmonary capillaries and the systemic capillaries into the tissues, according to Fick's laws of diffusion and the random walk of the diffusing particles.Author: J-Oc Dunn, MG Mythen, MP Grocott, MP Grocott
