Doody's Review ServiceReviewer: Antal G. Hudetz, PhD, Dr. Med.Bi(Medical College of Wisconsin)
Description: This is an excellent treatment of the technical fundamentals and latest developments of pulse oximetry, a noninvasive technique used to continuously monitor arterial oxygen saturation of patients.
Purpose: During the last decade, pulse oximetry underwent tremendous growth in popularity and has evolved into a standard monitoring device in most surgical and critical care units worldwide. While there have been previous detailed treatments of the subject, recent advances in optoelectronic design and signal processing techniques as well as the continuing need for empirical instrument calibration have made an update on the subject very desirable.
Audience: The book is recommended to anyone who is interested in better understanding of how pulse oximetry truly works, the physiological conditions affecting accurate operation, and the potential sources of error. It could serve as a basic text for engineers interested in pulse oximeter design, for scientists who wish to apply oximetry in nonroutine purposes, and for physicians who simply wish to have an in-depth understanding of the technique.
Features: The book first introduces the reader to enough circulatory physiology to understand the theoretical bases and practical aspects of various techniques of oximetry. It then describes in detail considerations for the fabrication of pulse oximeters, including mechanical, optical, electronic, and signal processing aspects. The book discusses various strategies that have been used for instrument calibration and the physiological sources of potential inaccuracies. It includes some essential data that allow technical comparison of several instruments on the market and briefly describes a range of applications of the technique under both standard and extreme conditions, such as high speed flight.
Assessment: The book is superbly written and should be clearly understandable to a wide audience. Written by a world-ranking research team lead by Webster at the University of Wisconsin at Madison, the chapters are consistent throughout the book and each provides full coverage of the subject.
