Cardiopulmonary exercise testing (CPET) is often seen as complex and difficult to interpret.As a result, many healthcare professionals are hesitant to use the test or feel overwhelmed when faced with a CPET report.A Practical Guide to the Interpretation of Cardiopulmonary Exercise Tests, Third Edition aims to demystify CPET by equipping clinicians with background knowledge and a structured approach to interpret and apply the data in clinical practice.The book is split into five sections: an introduction to the test and the rationale for its use, a description of the key CPET measured parameters, interpretation of this data, the use of CPET in more specialised clinical situations, and lastly a bank of questions testing the reader's knowledge.These questions are in the style of the Royal College of Physicians Respiratory Medicine exit exam.With practical tips and key learning points throughout, this guide is an essential resource for anyone looking to use CPET in their clinical practice.
