Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The International Society on OXygen Transport to Tissue (ISO'IT) has canpleted nine years as a society since its first fonnal meeting at Charleston-Clanson, South Carolina, United States of America in 1973. Prior to this time an active group of scientists and engineers rret in w::>rkshop environrrents, on a periodic basis, around the w::>rld. Meetings are ncM on an annual basis, alternating between Europe and the United States. The international gatherings include scientists and engineers in a variety of fields. ISOIT has produced a stable forum for the exchange of info:rmation on the rnicroenvirornnent of living cells, ranging fran the utilization of mathematics and engineering, through physiology and radiobiology, to clinical applications. The proceedings of these meetings have been codified into six books, four of them published by Plenum Press in its prestigious Advances in Experimental Medicine and Biology series. This volume, together with the next two volumes that will follCJV.l the meetings in Dortmund, Gennany in 1982 and in Ruston, Louisiana in 1983 will provide further chapters in the history of this fascinating field of knCJV.lledge. OUr thanks are given to all the participants and contributors to the Detroit meeting. We hope that the strength of the society will grow in caning years, and that our contribution will eventually be felt in :inproving the treatment of the sick, and in enhancing the thought processes of the intellectual.

Download or read book Capillary Fluid Exchange written by Joshua Scallan and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The partition of fluid between the vascular and interstitial compartments is regulated by forces (hydrostatic and oncotic) operating across the microvascular walls and the surface areas of permeable structures comprising the endothelial barrier to fluid and solute exchange, as well as within the extracellular matrix and lymphatics. In addition to its role in the regulation of vascular volume, transcapillary fluid filtration also allows for continuous turnover of water bathing tissue cells, providing the medium for diffusional flux of oxygen and nutrients required for cellular metabolism and removal of metabolic byproducts. Transendothelial volume flow has also been shown to influence vascular smooth muscle tone in arterioles, hydraulic conductivity in capillaries, and neutrophil transmigration across postcapillary venules, while the flow of this filtrate through the interstitial spaces functions to modify the activities of parenchymal, resident tissue, and metastasizing tumor cells. Likewise, the flow of lymph, which is driven by capillary filtration, is important for the transport of immune and tumor cells, antigen delivery to lymph nodes, and for return of filtered fluid and extravasated proteins to the blood. Given this background, the aims of this treatise are to summarize our current understanding of the factors involved in the regulation of transcapillary fluid movement, how fluid movements across the endothelial barrier and through the interstitium and lymphatic vessels influence cell function and behavior, and the pathophysiology of edema formation.

Download or read book Human Hemoglobins written by Howard Franklin Bunn and published by W.B. Saunders Company. This book was released on 1977 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the dawn of the era of molecular biology, hemoglobin has been subjected to more scrutiny than any other protein, and Bunn, Forget, and Ranney can each lay claim to major contributions to the saga of hemoglobin. Their well-organized, comprehensive, and superbly illustrated work is an excellent review of the abnormal hemoglobin field. Early chapters deal with the structure and function of human hemoglobin and the way in which this is modified in various disease states. Later sections deal with the various structural hemoglobin variants and their associated clinical manifestations, the thalassaemias, and the acquired disorders of hemoglobin. The sections that deal with the modification of hemoglobin function in various disease states are particularly good. The book contains an extensive and up-to-date bibliography and is remarkably free from errors of fact or type--the best standard of reference on the subject as of the year 1977.

Download or read book Compartment Syndrome written by Cyril Mauffrey and published by Springer Nature. This book was released on 2019-09-02 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compartment syndrome is a complex physiologic process with significant potential harm, and though an important clinical problem, the basic science and research surrounding this entity remains poorly understood. This unique open access book fills the gap in the knowledge of compartment syndrome, re-evaluating the current state of the art on this condition. The current clinical diagnostic criteria are presented, as well as the multiple dilemmas facing the surgeon. Pathophysiology, ischemic thresholds and pressure management techniques and limitations are discussed in detail. The main surgical management strategy, fasciotomy, is then described for both the upper and lower extremities, along with wound care. Compartment syndrome due to patient positioning, in children and polytrauma patients, and unusual presentations are likewise covered. Novel diagnosis and prevention strategies, as well as common misconceptions and legal ramifications stemming from compartment syndrome, round out the presentation. Unique and timely, Compartment Syndrome: A Guide to Diagnosis and Management will be indispensable for orthopedic and trauma surgeons confronted with this common yet challenging medical condition.

Available in PDF, EPUB and Kindle. Book excerpt: It can honestly be said that the scope and magnitude of this meeting surpassed initial expectations with respect to the number and quality of the papers presented. Our group has grown since we last met in Dortmund in 1971. This is a good indication that a spiraling of our interests has taken place with the effects of the initial good work felt, not just in one corner of the globe, but in all four. With such a start, it was only appropriate that an international society was formed at the meeting to further coordinate our mutual undertaking. Henceforth it shall be known as the International Society of Oxygen Transport to Tissue. A final note of acknowledgement should be made to those who were in the supporting cast, not only in making the meeting in Charleston and Clemson a success, but also in the compiling of this book. Gratitude is due to Dr. Daniel H. Hunt for his efforts, the end product of which you have in your hands. Considerable service was rendered by Mr. Robert J. Adams, Mr. Buddy Bell and Mr. Nathan Kaufman during the symposium itself. Much typing, organizing and record keeping was done by our lovely secretaries, Laura B. Grove, Muff Graham and Kaye Y. Zook.

Download or read book Oxygen Transport to Tissue IX written by Haim I. Bicher and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: These papers stem from the ISOTT Meeting held at Churchill College, Cambridge, from July 27th to 30th, 1986. Although the sun did not shine so brightly as during the Cambridge meeting in 1977, the communications and discussions were as lively and informative and some heat, as well as light, was generated in the presentation of differing views. The meeting was conducted in a generally informal way which allowed maximum time for discussion but the relatively unstructured nature of the debates made them unsuitable for publication. The amount of editing necessary meant that the printed version of the exchanges would bear little resemblance to the original, hence their omission. All the papers presented here have been scrutinized and retyped in a standard format. However, the diverse interests of ISOTT's members, reflected in the wide spectrum of the material submitted, made total editorial uniformity an unrealistic goal. Complete consistency in the use of symbols, abbreviations and units seemed less important than speed of publication.

Download or read book Oxygen Transport to Tissue V written by D. W. Lubbers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 893 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the understanding that few people ever read the preface to any book and also on the understanding that even those few people who do read the preface realize that virtually nothing of any substance is ever said, I shall write at such length as will be proportional to my expected readership. The meetings of the International Society on Oxygen Transport to Tissue provide a forum for discussion amongst scientists who, although being from very diverse and specialized backgrounds, have tissue oxygenation as a unifying theme of interest. The wide variety of research material presented in this volume and the multiplicity of the experimental techniques described, should serve as an adequate gauge to the range of expertise and knowledge of the society's members. Such diversity should also stress the importance of the need for multidisciplinary approaches to complex biological problems. In attempting a fundamental characterization of a biological process such as tissue oxygenation, the application of very many separate research skills are necessary, such as mathematics, engi neering, biophysics, biochemistry, physiology, histology and clini cal medicine. The success of the ISOTT has - and we hope - will con tinue to be causing a combination of individuals to direct their specialized knowledge to the many facets of a single proces- tissue oxygenation.

Download or read book Oxygen Transport to Tissue XI written by Karel Rakusan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ottawa '88 meeting of the International Society for Oxygen Transport to Tissue attracted a record number of participants and presentations. We were able to avoid simultaneous sessions and still keep the scientific program to four days by using poster sessions followed by plenary debate on each poster. To paraphrase the British physicist David Bohm, we tried to avoid an ordinary discussion, in which people usually stick to a relatively fixed position and try to convince others to change. This situation does not give rise to anything creative. So, we attempted instead to establish a true dialogue in which a person may prefer and support a certain point of view, but does not hold it nonnegotiab1y. He or she is ready to listen to others with sufficient sympathy, and is also ready to change his or her own view if there is a good reason to do so. Our Society is in its "teen" years, and there are even some arguments about its exact age. Many newer members have raised questions concerning the history of the Society. For this reason, I have asked one of the "founding fathers", D. Bruley, to prepare a brief account of the birth and early history of the Society which appears on the following page.

Available in PDF, EPUB and Kindle. Book excerpt: In this volume the policy of review by anonymous referees and minor correction by the editor has been continued, but perhaps should not be extended without an agreed policy statement by the Society. Our choice is minimal revision with rapid publication or proper review with some delay in publication. The editor wishes to express his gratitude to Ann Richardson, Joann Fish, Lance Johnson, and Philip Weinbrecht for their invaluable help in the preparation of this volume. Ian S. Longmuir v BRIEF HISTORY OF ISOTT The Society endured a long gestation period. During the 1960s its formation was discussed at a number of international meetings devoted to oxygen in biological systems. Prominent among a great number of such gatherings were those held at the Institute of Diseases of the Chest, London 1960; Bedford College, London 1963; Queen Elizabeth College, London 1963; and the Seventh Bad Oeynhausen Conference, 1967. At first, reservations were expressed about the desirability of forming a highly specialized society which might not achieve the "critical mass" necessary for its continued existence. However, the 1971 meeting in the Max Planck Institut fur Arbeitsphysiologie, Dortmund, answered these doubts, and Dr. Melvin Knisely commenced planning a very successful inaugural meeting in South Carolina. At this meeting in 1973 in Charleston and Clemson, the Society was formed with the customary remit of the promotion of scientific exchanges.
