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.

Book Description
Biologic markersâ€"indicators of biological exposure or changeâ€"offer the promise of early detection of disease caused by environmental exposure. Researchers have used these markers to discover indications of pulmonary damage from low-level ozone, a finding with serious implications for health professionals and environmental regulators. Biologic Markers in Pulmonary Toxicology is a comprehensive study of this use of biologic markers. Focusing on the respiratory tract as an entryway for airborne pollutants, this volume reviews new ways of measuring markers, the need for markers to indicate dose or exposure levels, noninvasive respiratory function tests for use with healthy humans to detect sensitivity to inhaled pollutants, approaches to evaluating markers down to the cellular and biochemical levels, and more.

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.

Book Description
The only text to cover lung function assessment from first principles including methodology, reference values and interpretation New for this edition: - More illustrations to convey concepts clearly to the busy physician - Text completely re-written in a contemporary style: includes user-friendly equations and more diagrams - New material covering the latest advances in the treatment of lung function, including more on sleep-related disorders, a stronger clinical and practical bias and more on new techniques and equipment - Uses the standard Vancouver referencing system What the experts say: "I have always considered Dr Cotes' book the most authoritative book published on lung function. It is also the most comprehensive." —Dr Robert Crapo, Pulmonary Division, LDS Hospital, Salt Lake City, USA "I think I can fairly speak on behalf of staff in lung function departments the length and breadth of the country - that a sixth edition of Cotes would be gratefully received." —Dr Brendan Cooper, Clinical Respiratory Scientist, Nottingham City Hospital

Book Description
The second edition of Fundamentals of Anaesthesia builds upon the success of the first edition, and encapsulates the modern practice of anaesthesia in a single volume. Written and edited by a team of expert contributors, it provides a comprehensive but easily readable account of all of the information required by the FRCA Primary examination candidate and has been expanded to include more detail on all topics and to include new topics now covered in the examination. As with the previous edition, presentation of information is clear and concise, with the use of lists, tables, summary boxes and line illustrations where necessary to highlight important information and aid the understanding of complex topics. Great care has been taken to ensure an unrivalled consistency of style and presentation throughout.

Book Description
This book represents an updated review of the physiology of the carotid body chemoreceptors. It contains results in the topics at the frontiers of future developments in O2-sensing in chemoreceptor cells. Additionally, this volume provides data from studies carried out in other O2-sensing tissues including pulmonary vasculature and erythropoietin producing cells. It is a prime source of information and a guideline for arterial chemoreception researchers.

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.
