Human Cardiovascular Control


Book Description

This new analysis of reflex and hormonal control of the human cardiovascular system developed from questions raised in Human Circulation: During Physical Stress (Rowell, 1986) and from recent findings. The goal is to help students, physiologists and clinicians understand the control of pressure, vascular volume, and blood flow by examining the cardiovascular system during orthostasis and exercise, two stresses that most affect these variables. A discussion of the passive physical properties of the vascular system provides a basis for explaining how vascular control is modified by mechanical, neural, and humoral factors. Interactive effects of the vasculature on cardiac performance are emphasized; they reveal the importance of autonomic control, supplemented by muscle pumping, in maintaining adequate ventricular filling pressure. The author's detailed analysis of how total oxygen consumption is restricted focuses on limitations in cardiac pumping ability, oxygen diffusion from lungs to blood and from blood to active muscle, oxidative metabolism and neural control of organ blood flow. An unsolved mystery is the nature of the signals that govern the cardiovascular responses to exercise. This is discussed in a new and critical synthesis of ideas and evidence concerning the "error signals" that are sensed and then corrected by activation of the autonomic nervous system during exercise.

Biomedical Technology and Devices, Second Edition


Book Description

Biomedical Technology and Devices, Second Edition focuses on the equipment, devices, and techniques used in modern medicine to diagnose, treat, and monitor human illnesses. Gathering together and compiling the latest information available on medical technology, this revised work adds ten new chapters. It starts with the basics, introducing the history of the thermometer and measuring body temperature, before moving on to a medley of devices that are far more complex. This book explores diverse technological functions and procedures including signal processing, auditory systems, magnetic resonance imaging, ultrasonic and emission imaging, image-guided thermal therapy, medical robotics, shape memory alloys, biophotonics, and tissue engineering. Each chapter offers a description of the technique, its technical considerations, and its use according to its applications and relevant body systems. It can be used as a professional resource, as well as a textbook for undergraduate and graduate students.

Each section contains a description of the technique, its technical considerations, and its use according to its applications and relevant body systems. The book includes references to relevant Web sites, protocols, problems, and solutions.




Cardiac Output and Regional Flow in Health and Disease


Book Description

Cardiac output has always been a subject of interest to both clinicians and researchers in different branches of medicine and surgery. In the last decade more attention has also been paid to its application in pediatrics, neonatology, fetal medicine and pregnancy. Better understanding of the peripheral circulation has provided more insight into the patholophysiology of different diseases. Many cardiac and non-cardiac disorders affect cardiac outputs. Monitoring of the changes in cardiac output is also important in the acutely ill patient. There are several methods to measure cardiac output, each with advantages and pitfalls. This book deals with all relevant aspects of cardiac output in eight parts: part one describes the methods of measuring cardiac output and a comparison between the catheterisation based and the noninvasive techniques, while part two describes the changes in cardiac output due to physiological causes. Part three describes cardiac output in cardiac diseases and systemic hypertension. Cardiac output in acutely ill patients is discussed in part four. Effect of cardiac medications, temporary atrial pacing, permanent pacing, pharmacologic stress testing and anesthesia are covered in detail in part six, while changes in cardiac output in noncardiac diseases are described in part seven. Finally great attention has been paid in part eight to the regional circulation including cerebral, coronary, skeletal and splanchnic circulations. A separate chapter discusses in detail the dynamics of blood flow. This book will be useful both to the cardiologists as well as to physicians in other fields of surgery and medicine and to their trainees. Readers will find this book an interesting and a useful reference on the topic of cardiac output.




Biomedical Signals, Imaging, and Informatics


Book Description

Known as the bible of biomedical engineering, The Biomedical Engineering Handbook, Fourth Edition, sets the standard against which all other references of this nature are measured. As such, it has served as a major resource for both skilled professionals and novices to biomedical engineering. Biomedical Signals, Imaging, and Informatics, the third volume of the handbook, presents material from respected scientists with diverse backgrounds in biosignal processing, medical imaging, infrared imaging, and medical informatics. More than three dozen specific topics are examined, including biomedical signal acquisition, thermographs, infrared cameras, mammography, computed tomography, positron-emission tomography, magnetic resonance imaging, hospital information systems, and computer-based patient records. The material is presented in a systematic manner and has been updated to reflect the latest applications and research findings.




Noninvasive Vascular Diagnosis


Book Description

The book provides the newest definitive text on the current techniques used in assessing vascular disorders. Readers will receive authoritative information and will be guided through the establishment and accreditation of a vascular laboratory and introduced to the physics of diagnostic testing. The chapters comprehensively explain the use of ultrasound in diagnosing cerebrovascular, renovascular, visceral ischemia and peripheral arterial disease, as well as venous disorders and deep abdominal vascular conditions. The book contains over 300 illustrations, many of them in color. The book will be invaluable to physicians who treat vascular disorders, surgeons, cardiologists, vascular radiologists and the vascular laboratory staff.




Blood Flow in the Heart and Large Vessels


Book Description

Cardiovascular fluid mechanics is now used as a tool in determining diagnosis, treatment, and prognosis by physicians and surgeons working in the fields of cardiology and angiology. The text is based on a considerable amount of clinical and experimental data on blood flow in the heart and large vessels obtained using various methods such as ultrasound pulsed Doppler velocimetry (including Doppler color flow imaging), catheter-tip electromagnetic velocimetry, hot-film anemometry, and laser Doppler velocimetry. The book will introduce medical researchers and clinicians to this rapidly developing field and allow them to apply the knowledge and the methods of fluid mechanics to practical medicine.
