This book provides learners with a unique opportunity by virtue of the format outlined above.  Each case presentation has a case vignette, which leads up to an important clinical question, and is followed by additional discussion which resolves the question posed. This is a new way to present knowledge in a medical book and should help critical care practitioners, fellows, residents, allied health professionals and students expand their critical care knowledge in an efficient and effective manner.  This approach should also benefit those preparing for board examinations.
