It provides a concise overview of the fundamental aspects and management strategies for critically ill patients using pathophysiological examinations of the most common problems encountered. Students, residents, and practitioners caring for critically ill patients are an appropriate audience for this book. The chapters are divided into two basic categories: general concepts/techniques/methods commonly used in ICU management and specific critical emergencies/crises encountered in medical/surgical ICU patients. There are detailed summaries of the physiological basis of disease manifestations as well as expert descriptions of technique, pitfalls and technology applications for ventilatory management, transfusion medicine, nutrition, and sedation, among others. Later chapters provide thorough descriptions of potential causes for emergent conditions such as COPD exacerbations, septic shock, drug overdose, burns and trauma, and detail important management steps. There are current descriptions of pharmacology applications with the latest options. The chapters are written in a standardized format and in a similar style (a benefit of only two authors), which makes the book easy to use. Much new information in this edition has greatly enhanced the utility of this book. Each chapter begins with a summary of key points that accurately captures the essence of the material. The full-color tables, figures, images, and descriptions have been thoroughly updated, revised, and expanded, leading to increased readability of the material and increased relevance of this book as a daily resource in the ICU. This book compares favorably with similar student preparatory books for ICU rotations including The Washington Manual of Critical Care, 3rd edition, Kollef et al. (Wolters Kluwer, 2018), Marino's The ICU, 4th edition, Marino (Lippincott Williams & Wilkins, 2014) and Critical Care Medicine: Principles of Diagnosis and Management in the Adult, 5th edition, Parrillo and Dellinger (Elsevier, 2019). What this book offers that makes it unique is the combined perspective of a pulmonary intensivist and a surgical intensivist. It offers a solid discussion of the basics and nuances of critical care issues and the implications of surgical disease on the physiology of our sickest patients. This is a must have for rotating senior students and junior residents taking an ICU rotation. Weighted Numerical Score: 92 - 4 Stars!
