Cardiopulmonary exercise testing (CPET) is an increasingly important investigation for anaesthesiologists, surgeons, cardiologists, pulmonologists, physiologists, and peri-operative physicians. For trainees, non-experts, or simply those seeking an introduction to interpreting CPETs, this essential book builds layers of knowledge that can be applied in case studies and in future practice. It will help you learn and understand: • What is CPET and what are the principles of exercise physiology • How to conduct a CPET • How to interpret a CPET nine-panel plot • How to assess exercise capacity and limitation. This practical and clinical guide is both easy to read and easy to understand and features diagrams illustrating key principles. It outlines the basic physiological principles and takes a step-by-step approach to conducting and interpreting a cardiopulmonary exercise test, together with case studies to consolidate learning. Chapters cover the indications and contraindications of CPET, test safety and complications, spirometry, writing a CPET report, and shared decision-making.
