Regulation of Tissue Oxygenation, Second Edition
Author: Roland N. Pittman
Publisher: Biota Publishing
ISBN: 1615047212
Category : Medical
Languages : en
Pages : 117
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.

How Tobacco Smoke Causes Disease
Author: United States. Public Health Service. Office of the Surgeon General
Publisher:
ISBN:
Category : Government publications
Languages : en
Pages : 728
Book Description
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Pediatric and Neonatal Mechanical Ventilation
Author: Peter C. Rimensberger
Publisher: Springer
ISBN: 3642012191
Category : Medical
Languages : en
Pages : 1584
Book Description
Written by outstanding authorities from all over the world, this comprehensive new textbook on pediatric and neonatal ventilation puts the focus on the effective delivery of respiratory support to children, infants and newborns. In the early chapters, developmental issues concerning the respiratory system are considered, physiological and mechanical principles are introduced and airway management and conventional and alternative ventilation techniques are discussed. Thereafter, the rational use of mechanical ventilation in various pediatric and neonatal pathologies is explained, with the emphasis on a practical step-by-step approach. Respiratory monitoring and safety issues in ventilated patients are considered in detail, and many other topics of interest to the bedside clinician are covered, including the ethics of withdrawal of respiratory support and educational issues. Throughout, the text is complemented by numerous illustrations and key information is clearly summarized in tables and lists.

The Oxford Handbook of Evolutionary Medicine
Author: Martin Brüne
Publisher: Oxford University Press
ISBN: 0192506781
Category : Medical
Languages : en
Pages : 967
Book Description
Medicine is grounded in the natural sciences, where biology stands out with regard to our understanding of human physiology and the conditions that cause dysfunction. Ironically though, evolutionary biology is a relatively disregarded field. One reason for this omission is that evolution is deemed a slow process. Indeed, the macroanatomical features of our species have changed very little in the last 300,000 years. A more detailed look, however, reveals that novel ecological contingencies, partly in relation to cultural evolution, have brought about subtle changes pertaining to metabolism and immunology, including adaptations to dietary innovations, as well as adaptations to the exposure to novel pathogens. Rapid pathogen evolution and evolution of cancer cells cause major problems for the immune system. Moreover, many adaptations to past ecologies have actually turned into risk factors for somatic disease and psychological disorder in our modern worlds (i.e. mismatch), among which epidemics of autoimmune diseases, cardiovascular diseases, diabetes and obesity, as well as several forms of cancer stand out. One could add depression, anxiety, and other psychiatric conditions to the list. The Oxford Handbook of Evolutionary Medicine is a compilation of up-to-date insights into the evolutionary history of ourselves as a species, exploring how and why our evolved design may convey vulnerability to disease. Written in a classic textbook style emphasising physiology and pathophysiology of all major organ systems, the Oxford Handbook of Evolutionary Medicine is valuable reading for students as well as scholars in the fields of medicine, biology, anthropology and psychology.

The Artificial Heart
Author: Institute of Medicine
Publisher: National Academies Press
ISBN: 0309045320
Category : Medical
Languages : en
Pages : 313
Book Description
A significant medical event is expected in 1992: the first human use of a fully implantable, long-term cardiac assist device. This timely volume reviews the artificial heart program-and in particular, the National Institutes of Health's major investment-raising important questions. The volume includes: Consideration of the artificial heart versus heart transplantation and other approaches to treating end-stage heart disease, keeping in mind the different outcomes and costs of these treatments. A look at human issues, including the number of people who may require the artificial heart, patient quality of life, and other ethical and societal questions. Examination of how this technology's use can be targeted most appropriately. Attention to achieving access to this technology for all those who can benefit from it. The committee also offers three mechanisms to aid in allocating research and development funds.
