This book sets out to provide perinatologists and neonatologists with an understandable explanation of the principles and application of commonly used technologies in their field, and to stimulate a more critical review of available biotechnology and its rational use. Each self-contained chapter is written by a physician, a bioengineer or a physicist, and together they present a clear account of the technology underlying each of the principal imaging modalities, tissue oxygenation measurement, electrical monitoring, ventilators, incubators and the measurement of blood flow and bilirubin levels, with a brief review of the practical uses of the technology, and an evaluation of its risks and benefits, including cost-effectiveness. A comprehensive reference for clinicians on the major technologies that have been applied in fetal and neonatal medicine. The many diagrams and illustrations provide a strong visual emphasis that will add further to its appeal to a broad clinical readership.
