I am a Senior Nursing Student doing my practicum on a large Intensive Care Unit. This book along with the little ICU book is a good reference for any one in critical care. Our Med/Surg Nursing Textbooks only graze over or do not cover some of the information need for critical care. There is very little discussion of Central Venous Pressure monitoring, Balloon Pumps, Neuro Surgical devices such as a ventriculostomy in school.I would highly recommend this book to anyone who is serious about critical care nursing. Not the best book to sit down and read, but well worth it for reference. Highly recommend splurging for the this one instead of the Little ICU book. I got both and got to where I would haul around the larger book for more information.UPDATEI graduated school and am now working at a busy Level 2 Trauma Center as an ER nurse. This book is an essential reference for the ER,or Critical Care Nurse.
