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.

Skeletal Muscle Circulation
Author: Ronald J. Korthuis
Publisher: Morgan & Claypool Publishers
ISBN: 1615041834
Category : Medical
Languages : en
Pages : 147
Book Description
The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

Human Hemoglobins
Author: Howard Franklin Bunn
Publisher: W.B. Saunders Company
ISBN:
Category : Medical
Languages : en
Pages : 456
Book Description
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.

Damage Control Resuscitation
Author: Philip C. Spinella
Publisher: Springer
ISBN: 3030208206
Category : Medical
Languages : en
Pages : 379
Book Description
This book provides a comprehensive overview of damage control resuscitation (DCR), an evidence-based approach to the resuscitation of patients with severe life-threatening hemorrhage (LTH). It focuses on both civilian and military applications as DCR is utilized in civilian trauma situations as well as combat casualty care settings. The book covers the history of fluid resuscitation for bleeding, epidemiology of severe traumatic injuries, prediction of life-threatening hemorrhage, pathophysiology and diagnosis of blood failure, and permissive hypotension. Chapters provide in-depth detail on hemostatic resuscitation principles, dried plasma, dried platelet surrogates, and recent developments in frozen red blood cells and oxygen carriers. The book also discusses how DCR principles can be used in a variety of situations such as when there are large numbers of patients with hemorrhagic lesions, non-trauma scenarios, and on distinct populations such as children. Finally, it concludes with a discussion of training and education methods for the implementation of DCR and remote DCR principles as well as learning healthcare system principles to facilitate the implementation of DCR and ultimately improve outcomes for patients with life-threatening hemorrhage. Damage Control Resuscitation: Identification and Treatment of Life-Threatening Hemorrhage is an essential resource for physicians and related professionals, residents, nurses and medical students in emergency medicine, anesthesia, surgery, and critical care, as well as civilian and military EMS providers.
