Book excerpt: This book uses real-world clinical case analyses of hot topics to provide insights into noninvasive mechanical ventilation (NIV). Written by leading international teachers and experts, it features a selection of “major controversial topics in clinical practice” and demonstrates how these cases can be used to teach about NIV. It then presents a discussion of the topics in various scenarios (anesthesiology, critical care, emergency, pneumology and sleep medicine, as well). The chapters allow readers to develop a case-by-case understanding of NIV in acute and chronic respiratory disorders, and perioperative and in intensive care patients, also thanks to Electronic Supplementary Materials. Lastly the authors summarize five key points / recommendations. This book is an attractive resource also for universities / educational seminars / national and international postgraduate courses and hot-topics sessions at national/international congresses.
