Book Description
This monograph clearly presents current analysis of gas exchange during exercise and explains how applications derived from the analysis is relevant to patient care. This book systematically addresses major aspects of respiration at the airway and muscle cells and their coupling by the heart and circulations during exercise. It also describes modern technology in gas analysis and use of computers applied to the study of patients with heart diseases. This simplifies what was formerly a time-consuming and complicated laboratory analysis and describes the broadened application of exercise testing

Book Description
The lung receives the entire cardiac output from the right heart and must load oxygen onto and unload carbon dioxide from perfusing blood in the correct amounts to meet the metabolic needs of the body. It does so through the process of passive diffusion. Effective diffusion is accomplished by intricate parallel structures of airways and blood vessels designed to bring ventilation and perfusion together in an appropriate ratio in the same place and at the same time. Gas exchange is determined by the ventilation-perfusion ratio in each of the gas exchange units of the lung. In the normal lung ventilation and perfusion are well matched, and the ventilation-perfusion ratio is remarkably uniform among lung units, such that the partial pressure of oxygen in the blood leaving the pulmonary capillaries is less than 10 Torr lower than that in the alveolar space. In disease, the disruption to ventilation-perfusion matching and to diffusional transport may result in inefficient gas exchange and arterial hypoxemia. This volume covers the basics of pulmonary gas exchange, providing a central understanding of the processes involved, the interactions between the components upon which gas exchange depends, and basic equations of the process.

Book Description
The first practical guide to fully explain how to use gas exchange techniques in clinical and research settings.With the increased use of gas exchange techniques in exercise testing, you will want to understand this technology and its applications. This helpful book presents important background material on exercise physiology and cardiopulmonary responses to exercise, and it features previously unavailable information on calibration procedures and quality control. You'll learn the following:- The physiology behind exercise testing- Ventilatory gas exchange methods and applications- What instrumentation and calculations to use for measuring gas exchange responses- What information can be obtained from gas exchange techniques- How to interpret gas exchange data- How to apply this information to different cardiovascular and pulmonary disorders- Normal values for exercise capacity and reference equations- How to apply more specialized applications of invasive hemodynamic measurementsThis unique book also features highlighted key terms, a glossary and list of scientific abbreviations, a detailed appendix of equations and examples for predicting oxygen uptake, and a list of equipment manufacturers and other helpful resources and organizations.

Book Description
This pocketbook guides clinicians through the parameters measured in CPEX testing so that they can understand the underlying physiology and are able to interpret the results.

Book Description
Maximum oxygen uptake during exercise is one of the best predictors of operative mortality and of prognosis in chronic cardiac or respiratory disease. Cardio-pulmonary exercise (CPEX) tests are therefore an increasingly common component of pre-operative assessment and the management of patients with chronic cardiopulmonary problems. Part of the Oxford Respiratory Medicine Library (ORML) series, this pocketbook guides clinicians through the parameters measured in CPEX testing so that they can understand the underlying physiology and are able to interpret the results. Clinical scenarios, common patterns, key points, and practical tips all make this book easy to follow, even for those readers who have little prior knowledge of the subject.

Book Description
Maximum oxygen uptake during exercise is one of the best predictors of operative mortality and of prognosis in chronic cardiac or respiratory disease. Cardiopulmonary exercise tests (CPET) are therefore an increasingly common component of pre-operative assessment and the management of patients with chronic cardiopulmonary problems. Part of the Oxford Respiratory Medicine Library (ORML) series, A Practical Guide to the Interpretation of Cardiopulmonary Exercise Tests, Second Edition provides readers with a practical, concise, and accessible approach to all aspects of cardiopulmonary exercise tests (CPET). CPET is often perceived as being incredibly complex to evaluate so this book breaks down interpretation to simple steps, allowing readers to rapidly understand the key points underpinning the application and interpretation of CPET. The text is focused and with the use of a substantial number of figures, learning points, and self-test questions helps readers to build confidence in undertaking and interpreting CPET. The second edition has been extended and extensively revised in line with the latest international guidelines and evidence, and includes 16 fully updated chapters, 4 new chapters, and a new section of worked examples has been added.
