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 chroniccardiopulmonary 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.
