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 volume contains the papers which were presented at the Third International Symposium on Oxygen Transport to Tissue together with the discussions at the end of each Session. The meeting was held at Churchill College, Cambridge from July 4th-7th 1977. Our special thanks are due to Mrs. Valerie Jeal and Mr. Charles Drown of the Department of Pathology, Bristol, who were invaluable in ensuring the smooth running of the meeting and the preparation of this book. We are very grateful to Dr. Marian Silver for proof-reading and helping to disentangle the "discussion". We would also express our thanks for the general help received from Janet and Fiona Silver and Steven James and our appreciation of the cheerful assistance of Miss Sadie Williams in putting the finishing touches to the manuscript.

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.
