Describes the hardware and software needed to make a pulse oximeter, and includes the equations, methods, and software required for them to function effectively. This book describes how oxygen is delivered to the tissue, historical methods for measuring oxygenation, and the invention of the pulse oximeter in the early 1980s. "? a complete guide to understanding, using, and designing the PO ? for biomedical engineers and for all those who need to know the technical workings of this instrument ? provides complete coverage of the field, from basic principles and techniques to signal-processing algorithms and calibration ? with an abundance of figures, tables, and equations, the book is easy to read and clear in understanding ? particularly useful for graduate students, biomedical technicians as the essential reference .. the best book to date ? ." -Valentin Grimblatov, Columbia-Presbyterian Medical Center, IEEE EMBS Magazine, May/June 1998 "? an excellent overview ? a must for biomedical engineers and medical physicists ? valuable contribution to clinical instrumentation and physiological measurement ? worth buying." -John Allen, Freeman Hospital, IFMBE News, May 1998
