The simple methods ordinarily used to measure the mean arterial blood pressure and to record its fluctuations serve some purposes very well but involve systems too heavy and sluggish to satisfy the needs of modern research. By means of the electrical manometers and networks described in this book, it is possible not only to follow rapid oscillations with high fidelity but also to obtain the first and higher order derivatives of pressure with respect to time. The concepts of overshooting, natural frequencies, and critical damping are clearly presented in an opening chapter; subsequent chapters discuss transducers, amplifiers, recorders, and differentiating and integrating circuits. There is a summary, bibliography, and index. The book will be indispensable to physiologists working in hemodynamics.
