This book by Dr. Marino with contributions by Dr. Sutin is a great book during rounds and gives a quick review of ICU facts. The data presented is well described, and difficult topics are explained as thoroughly as possible in a pocket book. The book covers a wide array of topics from ventilators to formulas often used in the ICU to nutrition with almost everything in between. Please do understand that this is a pocket book (so not all facts can be fully covered in detail), and Dr. Marino's main book is still considered a classic text for ICU rotations. This pocket book also has references to the specific journal article that the text is derived from. The diagrams and pictures are black and white, but this is not a negative aspect of the book. Overall, this is an excellent book for the ICU physician or any clinician needing to take care of critically ill patients. It's relatively small and portable, but can be a bit heavy while on long rounds in a white coat. Yes, I would buy this again knowing what data it contains.
