Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

Download or read book Monitoring of Cerebral Blood Flow and Metabolism in Intensive Care written by Andreas Unterberg and published by Springer. This book was released on 2012-02-28 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, monitoring of cerebral blood flow and metabolism was an unattained goal. Determination of cerebral blood flow was limited to intermittent measurements and particularly difficult to perform in critically ill patients. Meanwhile there are techniques available, however, to monitor cerebral blood flow and cerebral oxygenation, both globally and regionally. Therefore we thought it worthwhile to discuss these new continuous techniques and to compare them with well-known techniques which discontinuously measure CBF. For that purpose, an international workshop with some leading experts in the field was held in October 1992 in Berlin. The workshop consisted of about 20 lectures, either reviews on a special topic, or latest results. These contributions were given by invitation and were extensively discussed. Unfortunately it is impossible to reproduce the discussions. On the other hand, all speakers delivered a manuscript promptly after the meeting so that we were able to edit them within a short time. Since monitoring of cerebral blood flow in intensive care is a rapidly growing and changing topic, the written contributions should be quickly available. Authors, editors and publishers have tried to come close to this ideal. As editors we would like to thank the authors and the publishers who enabled us to come out with this volume of the proceedings as early as possible.

Download or read book Regulation of Tissue Oxygenation Second Edition written by Roland N. Pittman and published by Biota Publishing. This book was released on 2016-08-18 with total page 117 pages. 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.

Download or read book Angelo Mosso s Circulation of Blood in the Human Brain written by Marcus E. Raichle and published by Oxford University Press. This book was released on 2014-09-17 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern brain imaging is revolutionizing the study of brain function in health and disease. However, few realize that its origins began in the nineteenth century with Dr. Angelo Mosso's pioneering experiments. A foremost Italian physiologist and scientist, Angelo Mosso studied several patients brought to him with head injuries that exposed their live brains to direct, long-term observation. He took advantage of these rare opportunities to document, for the first time, changes in cerebral blood flow in response to different stimuli, behaviors, and emotions, the very same changes that are now the basis for the measurements underlying modern functional brain imaging. Mosso was widely recognized by his contemporaries for his highly original studies, published both in Italian in 1878 and in German in 1881. Yet there has never been a translation through which this groundbreaking work could be appreciated by the English-speaking world. Indeed, Angelo Mosso's sophisticated experiments were to neuroscience what surgeon William Beaumont's in vivo observations were to gastric physiology fifty years earlier. This unique monograph establishes Mosso's rightful role as the pioneer of brain imaging. Through it, the modern reader, whether expert neuroscientist or interested student, can gain a new perspective on the author's remarkable insights: how behaviors as subtle as thinking about a subject or feeling an emotion produce the changes in pulsations of the brain that he observed and recorded for posterity. Special features of this volume include first a brief summary of Mosso's life. Two pioneers of modern brain imaging, Marcus E. Raichle (winner of the Kavli Prize for Neuroscience) and Gordon M. Shepherd (Yale University Professor of Neurobiology) then review Mosso's work and provide extensive commentary to explain its relevance to modern brain science. The authors not only emphasize Mosso's pioneering role in brain imaging, but also his fundamental contribution to the rise of cognitive neuroscience. The English translation (by historian of medicine Christiane Nockels Fabbri) follows, together with all of the plates and illustrations of the original volume. The result is a classic of neuroscience, now available for wide appreciation by neuroscientists, neurologists, psychologists, psychiatrists, historians of science and medicine, and the general public.

Book excerpt: Every few years a dissertation comes to the area of clinical application of medical technology which carries us forward as on a magic carpet into new regions of understanding and patient care. This book is such a magic carpet. It brings together, in a clear and incisive fashion, important hemodynamic principles with a simple noninvasive method of application to a part of the cerebral vasculature which has been relatively inaccessible. To the lucky and perceptive person who reads this book, a feeling of excitement and hope for progress is engendered. The diligent application of the potentials of transcranial Doppler ultrasound brings new power to our efforts in understanding the cerebral circulation and the causes, treatment and prevention of cerebrovascular disorders. Merrill P. Spencer, M. D. Director Institute of Applied Physiology and Medicine Seattle, Wash. , July 1986 Acknowledgements I am greatly indebted to Prof. He1ge Nornes, Oslo, who introduced me to the fascinating study of cerebral hemodynamics in the early 1970's and since then continually encouraged my interest in this field. It was through his pioneering work on the cerebral circulation-using peroperative electromagnetic flowmetry and Doppler techniques-that the basis was laid for the noninvasive trans cranial approach to the circle of Willis described in this book. I also gratefully acknowledge the stimulating case discussions with Prof. Peter Huber, Berne, at the very early introduction of trans cranial Doppler, the inspiring exchange of ideas with Dr. Merrill P.
