The Egan's manual for respiratory therapy is the most beneficial learning tool and reference manual that I have come across in all of my career. The information in this book is not only easy to understand but layed out in a manner that makes finding what you need an easy task. It gives a thorough review of all the important clinical data and physical characteristics needed to become a competent practitioner... I would recommend this book as a reference tool to any student pursuing a career as a nurse, respiratory therapist, or physician. While this book may apply specific emphasis to the respiratory related field, it will reinforce your nursing or medicinal background by examining disease processes from a cardiopulmonary standpoint. This book has been a valuable learning tool and greatly aided me in both respiratory and nursing related classes.
