Book Description
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.

Book Description
This book is the first comprehensive overview of the emerging field of cuffless blood pressure monitoring. Increasing clinical evidence proves that longitudinal measurements of blood pressure allow for earlier detection and better management of multiple medical conditions and for superior prediction of cardiovascular events. Unfortunately, today’s clinical and industry standards for blood pressure monitoring still require the inflation of a pneumatic cuff around a limb each time a measurement is taken. Over the last decades clinicians, scientists and device manufacturers have explored the feasibility of technologies that reduce or even completely eliminate the need of cuffs, initiating the era of cuffless blood pressure monitoring. Among the existing literature, this book is intended to be a practical guide to navigate across this emerging field. The chapters of the handbook have been elaborated by experts and key opinion leaders in the domain, and will guide the reader along the clinical, scientific, technical, and regulatory aspects of cuffless blood pressure monitoring.

Book Description
Hardbound. Quantification is the key to clinical investigation and practice. Blood pressure measurement is however, bedevilled by problems relating to blood pressure variability - virtually a moving target. This volume intends to raise awareness about these limitations, but also to alert readers to the opportunities for clinical practice and research offered by accurate blood pressure measurement. The importance of ambulatory blood pressure measurement to overcome problems associated with isolated pressure values is addressed. The accuracy of measuring devices is considered, particularly in relation to various clinical subgroups. From the history of blood pressure measurement to the problematic issue of the use of SI units for quantification, this volume brings together the substantial amount of research in the field. Blood pressure behaviour is characterized in greater detail, with the aim of optimal patient management.
