I attempted to read this book in preparation for a critical care rotation at medical school. It went completely over my head. For example, I did not understand a fraction of the chapter on respiratory monitoring! There are so many symbols and subscripts used that I constantly had to skim back over the previous paragraphs/pages to remember what they all mean. To be honest, I found the book unreadable. I gave it 3 stars though as it seems that the authors have put a lot of effort into it, there are plenty of diagrams, and it appears extremely comprehensive and in depth - so I am sure people with more of a background in these areas will appreciate it. Hence, it may well be a very good book - I don't know (as I can't read it). But unless every med student at every other medical school has a much stronger grounding in respiratory physiology in particular, I really do not think this book is suited for medical students (as it claims to). Even areas which I feel I have quite a good grasp on (like acid-base, electrolytes) were difficult to read - basically, I had to pause after every sentence and check that I had understood it and how it followed on from the previous sentence as the authors seemed to skip about three steps of thought within the imaginary gap between sentences. Now I know that studying should be hard work, but for a book that claims to have "concise, easy to read chapters" (see back cover), I did not expect something like this. I may come back to it when I have read a couple of other books that will enable me to actually understand a bit about the subject and see what I think of it then. But - and I must have said this about five times by now - I do not believe it is a useful introductory text for someone who has absolutely no previous knowledge of the subject. I am curious to hear if someone else has a similar experience.
