Regulation of Tissue Oxygenation, Second Edition


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.




Hypoxia and Anoxia


Book Description

The molecular deprivation of oxygen is manifested by hypoxia, a deficiency of oxygen and anoxia, or the absence of oxygen supply to the tissues. This book entitled Hypoxia and Anoxia will cover a broad range of understanding on hypoxia and anoxia from molecular mechanisms to pathophysiology. Hypoxia and anoxia stimulate multiple systems through specific cell signal transduction pathways and regulate several transcriptional factors like HIF-1, REST to encode genes for VEGF, Epo, etc. This book will also highlight different types of hypoxia and anoxia along with their impact on apoptosis, cardiovascular pathophysiology, and glucose regulatory mechanisms. This book will be a ready reckoner to give a deep understanding of the oxygen-sensing environment in vivo for researchers, academicians, and clinicians throughout the world.




Hypoxic Respiratory Failure in the Newborn


Book Description

We have all been hypoxic. Fetal tolerance for intrauterine hypoxia arises from evolutionarily conserved physiological mechanisms, the antecedents of which can be learned from diving mammals or species at high altitudes. Understanding fetal hypoxia leads to understanding the huge physiological shifts of neonatal transition and the dangers of perinatal hypoxia. This comprehensive volume of topical review articles by expert authors addresses the origins of hypoxia tolerance, the impact of oxygen on circulatory transition at birth, and the biochemistry of hypoxia in the pulmonary circuit, as well as the classification, diagnosis, and clinical management of hypoxic respiratory failure and persistent pulmonary hypertension in the term neonate. The goal of Hypoxic Respiratory Failure in the Newborn is to connect our understanding of hypoxia from animals in extreme environments, with how the human fetus handles its hypoxic environment; and why the human newborn suddenly cannot. The book will educate health care professionals on how to care for newborns with hypoxic respiratory failure, including the use of up-to-date diagnostic tools and therapies. It also highlights areas of controversy and ongoing research in hypoxic respiratory failure and pulmonary hypertension of the newborn, including challenging case studies. Key Features Explores evolutionary context and comparative physiology of hypoxia tolerance in the fetus and neonate, from basic research to clinical scenarios Provides guidance to trainees, physicians, and allied health professionals engaged in NICU care; pediatricians, cardiologists, pulmonologists, anesthesiologists, neonatologists, and physiologists to effectively manage infants in hypoxic respiratory failure Includes case scenarios emphasizing current diagnostic and therapeutic controversies and algorithmic approaches to decipher difficult clinical cases




Vascular Biology of the Placenta


Book Description

The placenta is an organ that connects the developing fetus to the uterine wall, thereby allowing nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. Proper vascular development in the placenta is fundamental to ensuring a healthy fetus and successful pregnancy. This book provides an up-to-date summary and synthesis of knowledge regarding placental vascular biology and discusses the relevance of this vascular bed to the functions of the human placenta.




Physiologic and Pathologic Angiogenesis


Book Description

The purpose of this book is to highlight novel advances in the field and to incentivize scientists from a variety of fields to pursue angiogenesis as a research avenue. Blood vessel formation and maturation to capillaries, arteries, or veins is a fascinating area which can appeal to multiple scientists, students, and professors alike. Angiogenesis is relevant to medicine, engineering, pharmacology, and pathology and to the many patients suffering from blood vessel diseases and cancer, among others. We are hoping that this book will become a source of inspiration and novel ideas for all.




Handbook of CTG Interpretation


Book Description

This practical manual promotes an evidence-based paradigm of fetal heart rate monitoring during labour, moving away from the traditional 'pattern-based' interpretation to physiology-based interpretation. Aimed at obstetricians and midwives, it is useful to all those involved in multiprofessional intrapartum care.




Basic Physiology for Anaesthetists


Book Description

Easily understood, up-to-date and clinically relevant, this book provides junior anaesthetists with an essential physiology resource.




Core Topics in Critical Care Medicine


Book Description

The critical care unit manages patients with a vast range of disease and injuries affecting every organ system. The unit can initially be a daunting environment, with complex monitoring equipment producing large volumes of clinical data. Core Topics in Critical Care Medicine is a practical, comprehensive, introductory-level text for any clinician in their first few months in the critical care unit. It guides clinicians in both the initial assessment and the clinical management of all CCU patients, demystifying the critical care unit and providing key knowledge in a concise and accessible manner. The full spectrum of disorders likely to be encountered in critical care are discussed, with additional chapters on transfer and admission, imaging in the CCU, structure and organisation of the unit, and ethical and legal issues. Written by Critical Care experts, Core Topics in Critical Care Medicine provides comprehensive, concise and easily accessible information for all trainees.




Encyclopedia of Exercise Medicine in Health and Disease


Book Description

The Encyclopedia of Exercise Medicine is intelligently structured, easy accessible and user-friendly: A-Z format, clear, concise language and uniform essay structure as well as extensive cross references between keywords and related articles enables efficient searches in a user-friendly manner both for experts and newcomers. It is intended to be a comprehensive up-to-date data base on the adaptation of the human body to exercise and on the therapeutic use of exercise with up to 2,000 keywords. It covers all aspects within the full range of modern exercise medicine of each particular scientific discipline (cancer, parasitology, aging, etc.). This includes information on methodological approaches to measuring the principle components of motor fitness, and practical aspects of their enhancement by trainings regimes as well as by nutrition and the application of drugs. Such a wide range of entries, all written by leading experts in their respective fields, will therefore address both the basic/clinical scientist as well as the practitioner. Moreover, the Encyclopedia of Exercise Medicine is aimed at people in related fields, health care professionals, physiotherapists, trainers, students, informed athletes and interested laypersons. It is available both in print and as a fully searchable and hyperlinked electronic online edition.
