Download or read book Blood Donor Counselling written by World Health Organization and published by . This book was released on 2016-06-24 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Individuals who donate their blood provide a unique and precious gift in an act of human solidarity. In order to donate blood, prospective donors should be in good health and free from any infections that can be transmitted through transfusion. Most blood donors perceive themselves to be healthy, but some are unsuitable to donate blood due to the potential risk of compromising or worsening their own health or the risk of transmission of infections to patients. Blood transfusion services (BTS) have a duty of care towards blood donors as well as to the recipients of transfusion. This duty of care extends to prospective donors who are deferred from donation--whether on a temporary or permanent basis--as well as those who donate blood and are subsequently found to have unusual or abnormal test results. BTS have a responsibility to confirm test results and provide information, counseling and support to enable these individuals to understand and respond to unexpected information about their health or risk status. Counseling is part of the spectrum of care that a BTS should be able to provide to blood donors--including referral to medical practitioners or specialist clinical services. Pre-donation counseling was recognized as one element of the strategy to reduce and, if possible, prevent the donation of blood by individuals who might be at risk for HIV and other TTI including hepatitis B and C viruses as well as to inform the donor of the donation process and testing of blood for HIV. Post-donation counseling was acknowledged to be a necessary element of donor management as an adjunct to informing donors of unusual or abnormal test results. Blood donor counseling by trained specialist staff is now considered to be a key component of the blood system in most countries with a well-developed blood transfusion service. It may be required at a number of stages in the blood donation process or following blood screening and should be available at any point at which the BTS has an interface with donors. In many countries, however, blood donor counseling is not yet available in a structured way. Blood Donor Counselling: Implementation Guidelines has therefore been developed to provide guidance to blood transfusion services that have not yet established donor counseling programs.
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 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 HIV and the Blood Supply written by Institute of Medicine and published by National Academies Press. This book was released on 1995-10-05 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the early years of the AIDS epidemic, thousands of Americans became infected with HIV through the nation's blood supply. Because little reliable information existed at the time AIDS first began showing up in hemophiliacs and in others who had received transfusions, experts disagreed about whether blood and blood products could transmit the disease. During this period of great uncertainty, decision-making regarding the blood supply became increasingly difficult and fraught with risk. This volume provides a balanced inquiry into the blood safety controversy, which involves private sexual practices, personal tragedy for the victims of HIV/AIDS, and public confidence in America's blood services system. The book focuses on critical decisions as information about the danger to the blood supply emerged. The committee draws conclusions about what was doneâ€"and recommends what should be done to produce better outcomes in the face of future threats to blood safety. The committee frames its analysis around four critical area: Product treatmentâ€"Could effective methods for inactivating HIV in blood have been introduced sooner? Donor screening and referralâ€"including a review of screening to exlude high-risk individuals. Regulations and recall of contaminated bloodâ€"analyzing decisions by federal agencies and the private sector. Risk communicationâ€"examining whether infections could have been averted by better communication of the risks.

Download or read book Management of Blood Supply and Blood Demand to Ensure International Health Security written by Amar Ibrahim Omer Yahia and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintaining international health security requires proactive and reactive activities and actions to minimise the negative impact of any health event that threatens public health. Blood transfusion services are a critical part of healthcare services, and blood and blood products can neither be synthesized nor stored for a long period. So, proper management of blood supply and blood demand is mandatory to preserve adequate safe blood. A failure to manage blood inventory and the resulting blood shortage are considered national and international health security threats because maintaining an adequate supply of safe blood is lifesaving for many patients. Blood shortages lead to the failure of blood transfusion services that ends with the collapse of the health system and health insecurity if health authorities do not take immediate corrective action. An imbalance between blood supply and blood demand is not only a threat to health security, but also poses some of the greatest threats to the national and international economy and security. The perception of health issues as an international health security threat is associated with benefits through attracting political and decision-makers,Äô attention and support. The global health policies and international health regulations concerning the management of blood supply and blood demand should be implemented and updated regularly. The information provided by this chapter addresses the management of blood supply and blood demand as an international health security issue and provides guidance in planning for proper management of blood inventory to avoid a sudden blood shortage and its catastrophic consequences.
Download or read book Last Best Gifts written by Kieran Healy and published by University of Chicago Press. This book was released on 2010-08-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than any other altruistic gesture, blood and organ donation exemplifies the true spirit of self-sacrifice. Donors literally give of themselves for no reward so that the life of an individual—often anonymous—may be spared. But as the demand for blood and organs has grown, the value of a system that depends solely on gifts has been called into question, and the possibility has surfaced that donors might be supplemented or replaced by paid suppliers. Last Best Gifts offers a fresh perspective on this ethical dilemma by examining the social organization of blood and organ donation in Europe and the United States. Gifts of blood and organs are not given everywhere in the same way or to the same extent—contrasts that allow Kieran Healy to uncover the pivotal role that institutions play in fashioning the contexts for donations. Procurement organizations, he shows, sustain altruism by providing opportunities to give and by producing public accounts of what giving means. In the end, Healy suggests, successful systems rest on the fairness of the exchange, rather than the purity of a donor’s altruism or the size of a financial incentive.

This book was released on 2006-04-04 with total page 870 pages. Available in PDF, EPUB and Kindle. Book excerpt: In both rich and poor nations, public resources for health care are inadequate to meet demand. Policy makers and health care providers must determine how to provide the most effective health care to citizens using the limited resources that are available. This chapter describes current and future challenges in the delivery of health care, and outlines the role that operations research (OR) models can play in helping to solve those problems. The chapter concludes with an overview of this book – its intended audience, the areas covered, and a description of the subsequent chapters. KEY WORDS Health care delivery, Health care planning HEALTH CARE DELIVERY: PROBLEMS AND CHALLENGES 3 1.1 WORLDWIDE HEALTH: THE PAST 50 YEARS Human health has improved significantly in the last 50 years. In 1950, global life expectancy was 46 years [1]. That figure rose to 61 years by 1980 and to 67 years by 1998 [2]. Much of these gains occurred in low- and middle-income countries, and were due in large part to improved nutrition and sanitation, medical innovations, and improvements in public health infrastructure.
Download or read book Giving Blood written by Johanne Charbonneau and published by Routledge. This book was released on 2015-07-24 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Giving Blood represents a new agenda for blood donation research. It explores the diverse historical and contemporary undercurrents that influence how blood donation takes place, and the social meanings that people attribute to the act of giving blood. Drawing from empirical studies conducted in the United States, Canada, France, Australia, China, India, Latin America and Africa, the book’s chapters turn our attention to the evolution of blood donation worldwide, examining: the impact of technology advances on blood collection practices the shifting approaches to donor recruitment and retention the governance and policy issues associated with the establishment of blood clinics the political and legal challenges of regulating blood systems. This innovative examination moves the focus from individual explanations of rates of blood donation to a social, structural explanation. It will appeal to international scholars and students working in the areas of sociology, medical anthropology, health care, public policy, socio-legal studies, comparative politics, organizational management, health and illness, the history of medicine, and public health ethics.
Download or read book Blood and Oil written by Michael T. Klare and published by Metropolitan Books. This book was released on 2007-04-01 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the author of Resource Wars, a landmark assessment of the critical role of petroleum in America's actions abroad In his pathbreaking Resource Wars, world security expert Michael T. Klare alerted us to the role of resources in conflicts in the post-Cold War world. Now, in Blood and Oil, he concentrates on a single precious commodity, petroleum, while issuing a warning to the United States-its most powerful, and most dependent, global consumer. Since September 11th and the commencement of the "war on terror," the world's attention has been focused on the relationship between U.S. foreign policy in the Middle East and the oceans of crude oil that lie beneath the region's soil. Klare traces oil's impact on international affairs since World War II, revealing its influence on the Truman, Eisenhower, Nixon, and Carter doctrines. He shows how America's own wells are drying up as our demand increases; by 2010, the United States will need to import 60 percent of its oil. And since most of this supply will have to come from chronically unstable, often violently anti-American zones-the Persian Gulf, the Caspian Sea, Latin America, and Africa-our dependency is bound to lead to recurrent military involvement. With clarity and urgency, Blood and Oil delineates the United States' predicament and cautions that it is time to change our energy policies, before we spend the next decades paying for oil with blood.

Download or read book Trauma Induced Coagulopathy written by Hunter B. Moore and published by Springer Nature. This book was released on 2020-10-12 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of this publication was aimed at defining the current concepts of trauma induced coagulopathy by critically analyzing the most up-to-date studies from a clinical and basic science perspective. It served as a reference source for any clinician interested in reviewing the pathophysiology, diagnosis, and management of the coagulopathic trauma patient, and the data that supports it. By meticulously describing the methodology of most traditional as well as state of the art coagulation assays the reader is provided with a full understanding of the tests that are used to study trauma induced coagulopathy. With the growing interest in understanding and managing coagulation in trauma, this second edition has been expanded to 46 chapters from its original 35 to incorporate the massive global efforts in understanding, diagnosing, and treating trauma induced coagulopathy. The evolving use of blood products as well as recently introduced hemostatic medications is reviewed in detail. The text provides therapeutic strategies to treat specific coagulation abnormalities following severe injury, which goes beyond the first edition that largely was based on describing the mechanisms causing coagulation abnormalities. Trauma Induced Coagulopathy 2nd Edition is a valuable reference to clinicians that are faced with specific clinical challenges when managing coagulopathy.
