The Physiological Measurement Handbook

The Physiological Measurement Handbook presents an extensive range of topics that encompass the subject of measurement in all departments of medicine. The handbook describes the use of instruments and techniques for practical measurements required in medicine. It covers sensors, techniques, hardware, and software as well as information on processing systems, automatic data acquisition, reduction and analysis, and their incorporation for diagnosis. Suitable for both instrumentation designers and users, the handbook enables biomedical engineers, scientists, researchers, students, health care personnel, and those in the medical device industry to explore the different methods available for measuring a particular physiological variable. It helps readers select the most suitable method by comparing alternative methods and their advantages and disadvantages. In addition, the book provides equations for readers focused on discovering applications and solving diagnostic problems arising in medical fields not necessarily in their specialty. It also includes specialized information needed by readers who want to learn advanced applications of the subject, evaluative opinions, and possible areas for future study.

Designed to serve as a primary reference source for researchers and students interested in expanding their research to consider a biopsychosocial approach, this book provides a thorough, state-of-the-art, and user-friendly coverage of basic techniques for measurement of physiological variables in health psychology research.

Principles of Physiological Measurement examines the basic principles underlying the techniques and instruments used in making measurements, including tracer methods and compartmental analysis. It describes measurements of oxygen, carbon dioxide, pH, ammonia, and miscellaneous gases such as hydrogen and nitrogen. The book also describes the general concepts of electrical transduction, amplification, and recording. Organized into 15 chapters, this volume begins with an overview of some fundamental concepts of measurement, including basic gas and solution concepts, electronics relevant to measurement methods, and error in designing experiments. Some chapters are dedicated to the measurement of oxygen in gases and in aqueous solutions, partial pressure measurement of carbon dioxide in liquids, measurement of intracellular pH, and measurement of ammonia in gases and in solutions. Other chapters discuss the blood gas measurement, problems of controlling the gaseous environment, and basic principles of flow, velocity, force, displacement, and pressure, along with common methods for their measurement. The final chapters deal with ions and solutions, radioisotope concepts and techniques, and tracer kinetics. This book will be of interest to natural scientists and students in physiology courses.

Emotion Measurement, Second Edition highlights key elements of emotions that should be considered in the measurement of emotions in both academic and commercial environments. This edition begins with an updated review of basic studies of emotion, including the theory, physiology, and psychology of emotions, as these are the foundational studies which food scientists as well as product developers and marketing professionals need to be aware of. The second section highlights methods for studying emotions, and reviews the different approaches to emotion measurement: questionnaire self-report, behavioral, and physiological. This section explores the merits of intrinsic versus extrinsic measures of emotion. Some new measurement approaches have emerged since the first edition of this book. The book then presents practical applications, with chapters on emotion research in food and beverage, as well as in a range of products and clinical settings. The experience in testing product emotions has increased since the first edition when product emotion research was newer. Finally, Emotion Measurement, Second Edition provides coverage of cross-cultural research on emotions. This is critical because much of the newer commercial research is aimed at markets around the world, requiring methods that work in many cultures. And the universality of emotions has been a topic of research for decades. Taking both an academic and applied approach, Emotion Measurement, Second Edition will be an invaluable reference for those conducting basic academic research on emotions and for sensory and consumer scientists, and the product developers and marketing professionals they work alongside. Reviews both the academic and the applied strands of emotion measurement research Focuses on cross-cultural studies of emotions, which is currently lacking from most of the literature in the field Highlights methods for studying emotions in both basic and applied studies

During the last two decades, many new techniques and devices have appeared for measuring blood pressure both directly and indi rectly. At present, there is no single source for this information; nor is there information on the accuracy and sources of error expected with these technologies. It is for this reason that the present book was written. Divided into three parts: direct measurement, indirect (noninvasive) measurement, and history, the book is directed toward a broad audience in the medical and biological sciences. Physicians, nurses, medical students, and psychologists, as well as technical persons in the health care field will find Part One of considerable practical value, because it deals with the subject of the accuracy and fidelity of reproduction of blood pressure waveforms tha t they regularly view on monitors. The definitions of systolic, mean, diastolic, and capillary wedge pressures are illustrated and discussed. The pressures and waveforms at different sites in the cardiovascular system are described in detail. Then the various types of devices for measuring blood pressure are described and thoroughly illustrated. The effect of length and internal diameter of a catheter is analyzed to illustrate how fidelity of reproduction is affected. Simple tests are described that show the reader how to determine the performance characteristics of a catheter-transducer system. The characteristics of catheter-tip transducers are presented, and Part One concludes with a discussion of the rate of change of pressure (dP/dt), what it means, and how such a recording can be calibrated.
