Principles of Applied Biomedical Instrumentation

Earlier editions of this outstanding work dealt mainly with the measurement of physiological events. This Third Edition goes much further, not only revising the first two editions by presenting new applications of basic principles and a broader overall perspective, but also by including coverage of the latest therapeutic and rehabilitative devices. Four new chapters have been added dealing with stimulation and stimulators (Chapter 10), radiant-energy devices (Chapter 13), ventilators (Chapter 14), and anesthesia (Chapter 15). Chapter 10 covers the principles of excitation, monopolar and bipolar stimulation, and describes various output circuits such as constant-voltage, constant-current, and isolated-output. Numerous examples are presented, including cardiac pacing, ventricular defibrillation, and functional electrical stimulation. The radiant-energy devices in Chapter 13 cover light-emitting diodes, blackbody radiation, gas-discharge lamps, lasers, X-rays, lithotripsy, diathermy, the CT scanner, and electrosurgery. The different ways of providing artificial respiration are presented in Chapter 14 with specific coverage of how inspiration can be manipulated electrically by stimulating the nerves that control the inspiratory muscles. Chapter 15 covers inhalation anesthesia and the anesthetic machine from basic fundamental principles. The chapter also examines the method of delivering anesthetic. gases, estimating the depth of anesthesia, and anesthetic monitoring. Revised and expanded throughout, Principles of Applied Biomedical Instrumentation, Third Edition is designed for both the life scientist and physical scientist. Students will find the material easy to read, and teachers will find many examples of theory to be useful for lectures. For psychophysiology, nursing, and medical and veterinary students, the material explains new applications using biomedical instruments based on simple operating principles. Physicians and veterinarians preparing for board exams will find the nonmathematical presentation of instrumentation helpful, and engineering students will discover a wealth of new principles and techniques that can be used to design new instruments. The first edition appeared in 1968 and the second in 1975. Both explored the knowledge available at that time. Principles of Applied Biomedical Instrumentation, Third Edition reflects not only today's technology, but points toward tomorrow's.Geddes, Leslie A. is the author of 'Principles of Applied Biomedical Instrumentation', published 1989 under ISBN 9780471608998 and ISBN 0471608998.
