Monitoring Mechanical Ventilation Using Ventilator Waveforms

This book discusses the interpretation of mechanical ventilator waveforms. Each page shows a screenshot from a real patient and explains one or two messages. It starts with basic information about the waveforms and goes on to address passive and spontaneous ventilation, non-invasive ventilation and specific measurements such as pressure-volume curves and esophageal pressure. Step by step, readers learn about advanced monitoring of patient-ventilator synchronisation. This unique teaching approach has been adapted to this topic. Covering the entire field of mechanical ventilation, it is of particular interest to physicians and respiratory therapist working in emergency departments, anesthesiology, intensive care and respiratory units.

This book covers the up-to-date advancement of respiratory monitoring in ventilation support as well as detecting the physiological responses to therapeutic interventions to avoid complications. Mechanical ventilation nowadays remains the cornerstone in life saving in critically ill patients with and without respiratory failure. However, conclusive evidences show that mechanical ventilation can also cause lung damage, specifically, in terms of ventilator-induced lung injury. Respiratory monitoring encloses a series of physiological and pathophysiological measurements, from basic gas exchange and ventilator wave forms to more sophisticated diaphragm function and lung volume assessments. The progress of respiratory monitoring has always been accompanied by advances in technology. However, how to properly conduct the procedures and correctly interpret the data requires clear definition. The book introduces respiratory monitoring techniques and data analysis, including gas exchange, respiratory mechanics, thoracic imaging, lung volume measurement, and extra-vascular lung water measurement in the initial part. How to interpret the acquired and derived parameters and to illustrate their clinical applications is presented thoroughly. In the following part, the applications of respiratory monitoring in specific diseases and conditions is introduced, including acute respiratory distress syndrome, obstructive pulmonary diseases, patient-ventilator asynchrony, non-invasive ventilation, brain injury with increased intracranial pressure, ventilator-induced diaphragm dysfunction, and weaning from mechanical ventilation. This book is intended primarily for ICU physicians and other practitioners including respiratory therapists, ICU nurses and trainees who come into contact with patients under mechanical ventilation. This book also provides guidance for clinical researchers who take part in respiratory and mechanical ventilation researches.

A user-friendly guide to the basic principles and the technical aspects of mechanical ventilation and modern complex ventilator systems

Designed for courses in Mechanical Ventilation and/or Ventilation Graphics, this text introduces ventilator waveforms. It is intended to serve as a complement to a mechanical ventilation textbook and as a reference convenient to carry in the clinical environment. The first chapter provides clean, easy-to-read conceptual illustrations to aid in comprehension. Examples of real waveforms are provided next to the conceptual renderings to allow the learner to become comfortable with viewing waveforms with normal artifact present. The following chapters utilize mostly real recordings of ventilator waveforms. The rationale behind the format of this text is to provide a simple, portable reference and workbook that can be used at the bedside as well as the classroom. Descriptions and commentary are kept to a minimum to enhance clarity and readability. Ventilator waveform topics that are experimental, in limited use, or not considered mainstream are not included in keeping with this book's introductory theme. It would be impractical and ponderous to attempt to include all possible examples of ventilator waveforms that can be seen in the clinical setting. The goal of this book is to impart an understanding of how waveforms are generated, which will allow the practitioner to deduce the cause and implications of previously unseen as well as familiar waveforms. Understanding waveforms, instead of memorizing many patterns, aids in problem solving and correction of abnormal conditions and prepares clinicians to adapt to future yet unknown modes of ventilation.

Simplify, simplify! Henry David Thoreau For writers of technical books, there can be no better piece of advice. Around the time of writing the first edition – about a decade ago – there were very few monographs on this s- ject: today, there are possibly no less than 20. Based on critical inputs, this edition stands thoroughly revamped. New chapters on ventilator waveforms, airway humidification, and aerosol therapy in the ICU now find a place. Novel software-based modes of ventilation have been included. Ventilator-associated pneumonia has been se- rated into a new chapter. Many new diagrams and algorithms have been added. As in the previous edition, considerable energy has been spent in presenting the material in a reader-friendly, conv- sational style. And as before, the book remains firmly rooted in physiology. My thanks are due to Madhu Reddy, Director of Universities Press – formerly a professional associate and now a friend, P. Sudhir, my tireless Pulmonary Function Lab technician who found the time to type the bits and pieces of this manuscript in between patients, A. Sobha for superbly organizing my time, Grant Weston and Cate Rogers at Springer, London, Balasaraswathi Jayakumar at Spi, India for her tremendous support, and to Dr. C. Eshwar Prasad, who, for his words of advice, I should have thanked years ago. vii viii Preface to the Second Edition Above all, I thank my wife and daughters, for understanding.

This book clearly and systematically covers mechanical ventilators by discussing what they do, how they work, what they are used for and how they are used on patients. The third edition has been completely reorganised from past editions to present the material in a more logical way, reflective of the mechanical ventilation unit in the respiratory curriculum. Content is divided into five sections covering basic concepts, patient monitoring, effects/complications of ventilators, patient management and specialised mechanical ventilation. This organisation progresses from the basic to more advanced applications of mechanical ventilation. This edition uses several different student-oriented pedagogical features and a new art program with professional rendering of equipment and physiological principles. * Covers all advancements in the field of mechanical ventilation, including liquid ventilation and high frequency ventilation making this the authoritative mechanical ventilation textbook and bench reference. * Reviews history, basic terms, and concepts of mechanical ventilators. New organisation better reflects the order in which respiratory instructors teach their students the principles and application of mechanical ventilation in the classroom. Many chapters have been completely rewritten, revised, or updated. A new chapter on troubleshooting and problem solving explains how to identify when a patient is in distress and what actions should be taken to help the patient. New, separate chapters on Ventilator Graphics provides the necessary foundation for understanding pressure, volume and flow graphics. Decision Making and Problem Solving boxes ask the reader a clinical question or present the reader with a patient case to put difficult concepts into clinical context. Case studies have been revised to help readers improve their critical thinking skills. Increased quality of graphics illustrate extremely technical equipment and context. Boxes including historical notes, term definitions and key clinical concepts improve interior layout.
