Book Description
In the past decade noninvasive, nontraumatic methods of monitoring parameters of physiological function have been investigated with increasing interest. Of the various parameters of cardiac function, only blood pressure and the electrical activity of the myocardium have tradionally been accessible noninvasively, and only the latter in a continuous fashion. Several invasive methods exist for measurement of myocardial contractility, cardiac output, the degree of heart failure, etc., and a few for watching some of these factors noninvasively, but not, in general, non- invasively, conveniently, comfortably, and continuously. Monitoring the changing thoracic electrical impedance is a technique which satisfies all these criteria. Some of the theory of biological impedance change is discussed, and some of the drawbacks are pointed out. A survey of the literature of the last decade is presented, illustrating the fact that many investigators have consistently obtained good correlation with 'standard' invasive techniques of measurement, while others have had variable results. Some of the unexplored areas in this field are discussed and directions for future research suggested.

Book Description
The book is divided in 4 parts. In the first one, the importance of the analysis of the cardiac dynamics using the ambulatory monitoring technique is presented. The second part contains the description of foundations of impedance cardiography (ICG), the models used to describe the ICG technique and the description of available systems for ambulatory monitoring of cardiac hemodynamics. The third part is devoted to the validation of the ambulatory ICG method, the verification of the quality of long term ICG recordings and the discussion of the limitations of this technique. In the last part, some clinical and research applications of the ICG ambulatory monitoring are presented. The simultaneous recordings of electrocardiogram (ECG) and ICG in the transient cardiac arrhythmia events illustrate the potential applications of that method for quantitative analysis of hemodynamics when the implementation of the stationary methods would be either difficult or not possible to do. The book is followed by references, alphabetical index and appendices containing the technical data of the available systems for portable monitoring of cardiac hemodynamics.

Book Description
Critical care medicine is a dynamic and exciting arena where complex pathophysiologic states require extensive knowledge and up-to-date clinical information. An extensive kno- edge of basic pathophysiology, as well as awareness of the appropriate diagnostic tests and treatments that are used to optimize care in the critically ill is essential. Since our frst edition 7 years ago, new information crucial to the care and understanding of the critically ill patient has rapidly accumulated. Because this knowledge base crosses many different disciplines, a comprehensive multidisciplinary approach presenting the information is essential, similar to the multidisciplinary approach that is used to care for the critically ill patient. We have strived to provide this content in an easily digestible format that uses a variety of teaching tools to facilitate understanding of the presented concepts and to enhance information retention. To meet the demand to provide comprehensive and diverse education in order to und- stand the pathogenesis and optimum care of a variety of critical illnesses, we have subst- tially revised the prior topics in the frst edition with updated information. We have also markedly expanded the number of topics covered to include acute lung injury and the acute respiratory distress syndrome, an expanded discussion of the physiology and operation of mechanical ventilation, obstetrical care in the ICU, neurosurgical emergencies, acute co- nary syndromes, cardiac arrhythmias, role of whole body rehabilitation in the ICU, ethical conduct of human research in the ICU, and nursing care of the ICU patient.

Book Description
Impedance cardiography is an important tool in determining a person’s hemodynamic properties. The makers obtained through thoracic impedance have been shown to be of great importance when monitoring critical care patients. Technological developments have made this process noninvasive and ambulatory, opening up new possibilities for potential use. A study was conducted by remotely monitoring healthy subjects (n=5), who performed an 8-minute mild-to-moderate aerobic exercise protocol, followed up by a four minute cognitive stress test. Testing was conducted onsite at Kennedy Space Center in association with the National Aeronautics and Space Administration using the MW1000A (MindWare Technologies LTD, Gahanna, OH) ambulatory impedance cardiography monitoring (ICG) device.

Book Description
Biomedical transducers are essential instruments for acquiring many types of medical and biological data. From the underlying principles to practical applications, this new book provides an easy- to-understand introduction to the various kinds of biomedical transducers. The first comprehensive treatment of this subject in 20 years, the book presents state-of-the-art information including: discussions of biomedical transducers for measurements of pressure, flow, motion, temperature, heat flow, evaporation, biopotential, biomagnetism, and chemical quantities. Chapters are devoted to particular areas of instrumentation needs
