The Guest Editors, Pierre-Régis Burgel, Marco Contoli and José Luis López-Campos, have selected and integrated the topics covered to create a book that successfully summarises current knowledge in this area. I thank the Guest Editors and all of the authors for their hard work on this excellent book. Together, they have produced a practice-guideline publication, comprising information about scientific background and application at the patient’s bedside. I am sure that this comprehensive review will prove useful in the clinical practice of a broad range of respiratory physicians, and will improve the care of patients that experience AEs.
