I agree. The ICU Book by Marino is great. After reading it, I felt that it had more of his "opinions" than actual standard of care. But after asking two pulmonologists about it, they both said it was a great book for my level (as a 4th year). Plus, its pretty easy to read. I bought mine used on Amazon for 30 something. It is too big to put in your labcoat but ok to carry around on top of a clipboard.
