With a focus on chemistry and physics content that is directly relevant to the practice of anesthesia, this text--written in an engaging, conversational style--supplies all the scientific information required for the combined chemistry and physics course for nurse anesthesia students. Now in its third edition, the text is updated and reorganized to facilitate a greater ease and depth of understanding. The addition of a third author--a practicing nurse anesthetist--enhances the clinical relevance of the scientific information. Clinical scenarios now begin every chapter, and a concluding chapter, new to this edition, provides detailed, step-by-step solutions to the book's review questions. Also included is a comprehensive list of need-to-know equations.
