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 Cardiopulmonary Monitoring written by Sheldon Magder and published by Springer Nature. This book was released on 2021-09-01 with total page 952 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive overview of the basic physiology of the cardiac and pulmonary systems, tools for cardiopulmonary monitoring, and related issues in the management of specific conditions. The volume is divided into three main parts. The first part examines the functional basis of normal and abnormal physiology, organized into cardiac and pulmonary units and followed by a “combined” interactive component. The next section discusses cardiopulmonary monitoring tools and variables and is also divided into cardiac (e.g, echocardiography, heart rate, cardiac output), pulmonary (e.g, lung volume, pleural pressure, electrical impedance tomography), and combined tools such as radiology/MRI and tissue perfusion tests. The third section concerns the management and application of specific clinical problems such as pulmonary hypertension, cardiac shunts, cardiogenic shock, and ECMO with an emphasis on the physiological basics. /div Cardiopulmonary Monitoring: Basic Physiology, Tools, and Bedside Management for the Critically Ill is an essential resource for physicians, residents, fellows, medical students, and researchers in cardiology, critical care, emergency medicine, anesthesiology, and radiology.

Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the respiratory function of vertebrate red cells. I have defined the phrase "respiratory function" broadly to include, in addition to the actual oxygen and carbon dioxide transport, erythropoiesis, haemoglobin synthesis, red cell structure, the deformability of red cells in circulation, ion and substrate transport across the cell membrane, cellular metabolism, and control of cellular volume and pH. All of these aspects of the red cell function may affect gas transport between the respiratory epithelia and the tissues. Throughout the book, I have tried to relate our current knowledge about the nucleated red cell function to the wealth of information about the function of mammalian red cells. However, whenever possible, I have placed the emphasis on the nucleated red cell function for two reasons. First, the erythro cytes of 90% of vertebrate species are nucleated, and, second, nucleated red cell function has not been reviewed earlier in a single volume. This being the case, I have tried to make the reference list as complete as I could with regard to nucleated red cells. I hope that the approach adopted is useful for both com parative and human physiologists. Many people have contributed to the making of this book directly or in directly. Antti Soivio started me in this field. Prof. Henrik Wallgren has always encouraged fresh scientific ideas in his department. My present ideas of red cell function have been influenced by work carried out with Prof. Roy E.

Download or read book Regulation of Haemoglobin Synthesis written by J. Neuwirt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Haemoglobin is one of the most important molecules in the animal kingdom. Its function is to carry oxygen to tissues. In lower invertebrates the blood pigment is present in the haemolymph and is not bound in cells. Later in the course of phylo genesis haemoglobin remains associated with cells which produce it and in this form it reaches the peripheral circulation. In higher organisms the haemoglobin production is thus determined by two main factors: haemoglobin synthesis in erythroid cells and the formation of these erythroid cells which depends on cell proliferation in haematopoietic organs. Human haemoglobin is made up of two chains which combine from four different polypeptide chains formed in varying ratios in different periods of the life cycle. During the life span of humans the following haemoglobins are formed: embryonic haemoglobins Gower 1 and 2, foetal haemoglobin F and two adult haemoglobins A and A . E-and IX-chains are part of the embryonic haemoglobins Gower 1 (E4) and 2 Gower 2 (1X2E2). These haemoglobins predominate in embryos during the second month of pregnancy and at the end of the first trimester they are completely re placed by foetal haemoglobin F (~Y2). Adult haemoglobin A consists of two IX and two ~-chains and is the main component of red cells in adults. A relatively small component of red cells accounting for less than 2 % of the total haemo globin, is haemoglobin A2 (1X0).
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 The Respiratory Functions of Blood written by Lars Garby and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is the first of a series which is designed to present in depth timely reviews of subjects related to the blood. Insofar as each subject lends itself, the clinical aspects of each topic will be presented as fully as is appropriate, in addition to the basic features. As a consequence, the various monographs should be found useful not solely by hematologists. Depending on the nature of each topic, it is expected that these monographs will be found important by physiologists and specialists in fields other than hematology, as well as by scientists of very diverse interests. The present treatise illus trates this point. Doctors Garby and Meldon have brought together in a most useful way the spectacular advances which have been made in the last decade or two in a field of fundamental biologic impor tance. They have also brought to the discussion of this subject their own observations and interpretations as well as their profound understanding of the respiratory functions of the blood. Maxwell M. Wintrobe Salt Lake City, Utah v Preface This volume is an attempt to summarize the present state of know ledge of the respiratory functions of blood in health and disease. Though it deals fairly thoroughly with physicochemical aspects of the blood's gas transport properties and with the molecular chemis try of hemoglobin, its main emphasis is the gas transport function of the blood in vivo and modes of its disturbance in disease.
