Available in PDF, EPUB and Kindle. Book excerpt: Man has conquered Everest, been to the bottom of the deepest ocean, and even walked on the Moon by understanding pressure and oxygen. But the one area of life the technology has not influenced is the practice of medicine. Billions have been spent researching drugs to treat the brain and they have failed; drug companies are closing their neuroscience laboratories. This is because there is no substitute for oxygen. As the most astonishing discovery since DNA was unraveled has shown, oxygen, the gas in the air we all breathe, controls our most important genes. If we are sick or seriously injured and in intensive care, the amount of oxygen we can be given is limited by the weather. Without a simple pressure chamber, we are forced to accept a variation of more than 10% when just 2% more oxygen on the summit of Everest can mean the difference between life and death. We have already engineered the solution; the technology used in aircraft that sustains us flying at 40,000 feet can facilitate medical recovery safely on the ground. This book follows the human journey from conception to old age and presents evidence amassed over more than a century that can transform the care of patients with birth injury, head trauma, multiple sclerosis, stroke, and even reverse decline in old age. There is no more necessary and scientific action than to correct a deficiency of oxygen, especially in the brain and it is simple to give more.
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 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 The Brain Without Oxygen written by P.L. Lutz and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known and researched, that deprivation of oxygen to the brain can quickly result in irreversible damage and death. What is less well known, is that some vertebrate species are exceptionally tolerant of brain hypoxia. The Brain Without Oxygen: Causes of failure - Physiological and molecular mechanisms for survival, Third edition, discusses the mechanisms of brain hypoxia tolerance in these exceptional vertebrates, which include diving marine mammals, high altitude dwellers and the hibernating mammal. Special attention is given to the extraordinary adaptations that allow a few turtle and fish species to tolerate months of brain anoxia. This third, fully updated edition addresses the potential of these animal models as targets for human clinical intervention. Perhaps the most interesting of these, are those involved in the suppression of metabolic activities to new set points well below their normoxic minima or maintenance levels. This volume will be valuable reading for researchers in physiology, medicine and general biological sciences, and of great importance to pharmaceutical companies researching novel models for stroke and brain ischemia.

Download or read book The Oxygen Revolution Third Edition written by Paul G. Harch, M.D. and published by Hatherleigh Press. This book was released on 2016-06-21 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cutting-edge research on hyperbaric oxygen therapy (HBOT) as a gene therapy to treat traumatic brain injuries, degenerative neurological diseases, and other disorders Hyperbaric oxygen therapy (HBOT) is based on a simple idea—that oxygen can be used therapeutically for a wide range of conditions where tissues have been damaged by oxygen deprivation. Inspiring and informative, The Oxygen Revolution, Third Edition is the comprehensive, definitive guide to the miracle of hyperbaric oxygen therapy. HBOT directly affects the body at the genetic level, affecting over 8,000 individual genes—those responsible for healing, growth, and anti-inflammation. Dr. Paul G. Harch’s research and clinical practice has shown that this noninvasive and painless treatment can help those suffering from brain injury or such diseases as: • Stroke • Autism and other learning disabilities • Cerebral palsy and other birth injuries • Alzheimer’s, Parkinson’s, multiple sclerosis, and other degenerative neurological diseases • Emergency situations requiring resuscitation, such as cardiac arrest, carbon monoxide poisoning, or near drowning For those affected by these seemingly “hopeless” diseases, there is finally hope in a proven solution: HBOT.
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.
