Proceedings of the August 1995 meeting, presenting reports by physicists, chemists, clinicians, engineers, and biochemists on major developments in the delivery of oxygen to tissues. Papers are organized in sections on assessment of dysoxia, myocardial hypoxia-ischemia, tissue oxygen distribution, tissue oxygenation in tumors, oxygen supply-demand, angiogenesis and microcirculation, oxygen carriers, and anticoagulants and tissue oxygenation. Highlights include discussion of clinical application of NIR spectroscopy and cerebral oximetry, protein kinase C separation and production on an industrial level from transgenic animals, and the roles of nitric acid and oxygen free radicals to tissue injury and tissue oxygenation.
