Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
This book covers the proceedings of the 32nd scientific meeting of the International Society on Oxygen Transport to Tissue (ISOTT) in Bari, Italy, August 21-26, 2004. It covers all aspects of oxygen delivery to tissue, including blood flow and its regulation as well as oxygen metabolism. Special emphasis is placed on methods of oxygen measurement in living tissue and application of these technologies to understanding physiological and biochemical basis for pathology related to tissue oxygenation. The event hosted was a multidisciplinary meeting designed to bring together experts and students from a range of research fields.

Book Description
The International Society on Oxygen Transport to Tissue (ISOTT) was founded in 1973 "to facilitate the exchange of scientific information among those interested in any aspect of the transport and/or utilization of oxygen in tissues". Its members span virtually all disciplines, ex tending from various branches of clinical medicine such as anesthesiology, ophthalmology and surgery through the basic medical sciences of physiology and biochemistry to the physical sciences and engineering. The fifteenth annual meeting of ISOTT was held in 1987 for three days, from July 22 to 24, at Hokkaido University in Sapporo, Japan. Previously, all ISOTT meetings had been held in Europe or the USA alternatively. This time, however, the meeting was held for the first time in an Asian country. When we first started preparing for this meeting some of our members were afraid that the number of those attending would not exceed '30. Fortunately the results were quite different. We had more than 60 participants from abroad and an even greater number from Japan. In addition to three special lectures and two symposia there were a total of 88 posters presented over the three days of the meeting. These covered all aspects of physiological oxygen transport including convection, diffusion, chemical reaction, and control of oxygen demand in blood and various tissues as well as the methods, models and instrumentation for their study. The 92 papers which comprise this volume encompass all of these areas.

Book Description
The 30th scientific meeting of the International Society on Oxygen Transport to Tissue (ISOTT) was held at the Western Conference Centre, UMIST, Manchester, in August 2002. It was attended by some 96 delegates and accompanying persons and there were 128 presentations.

Book Description
This volume contains refereed manuscripts prepared from presentations made at the 2ih annual meeting of the International Society on Oxygen Transport to Tissue (ISOTT). The meeting was held in Hanover, NH, USA, at Dartmouth Medical School, the 3rd oldest medical school in the USA. ISOTT attempts to produce high quality pUblications on cutting edge topics relating to oxygen in living systerns. The goal is to allow contributors to contribute original data, as with a main-stream journal article, but also to voice individual opinions and ideas in a more relaxed scientific forum. The meeting brought together an international group of scientists who share a common interest in the measurement and role of oxygen in living systems. The organizers of ISOTT99 made a special effort to bring together people from industry, medicine, and basic sciences in order to improve the links in the chain of discovery through to application. As a result, this volume contains publications on a range of subjects. There are contributions from companies on modifiers of oxygen carrying capacity (allosteric modifiers of hemoglobin and infusible oxygen carriers or blood substitutes); technical reports on oxygen measurement devices including advances in near-infrared spectroscopy and imaging, oxygen electrodes, magnetic resonance spectroscopy and imaging, and fluorescence based measurements. There are medically related sections on modifying and measuring tumor oxygenation in order to improve therapy, assessment and interpretation of oxygenation in the central nervous system, and general issues relating oxygen to pathological conditions.
