This book presents detailed descriptions of how to set up and use several classical cardiac preparations from scratch, including whole heart, atrial, ventricular, and papillary muscles and in vivo small animal preparations. It describes methods for monitoring contraction and contractility.
Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.
This book offers a comprehensive overview of the basic physiology of the cardiac and pulmonary systems, tools for cardiopulmonary monitoring, and related issues in the management of specific conditions. The volume is divided into three main parts. The first part examines the functional basis of normal and abnormal physiology, organized into cardiac and pulmonary units and followed by a “combined” interactive component. The next section discusses cardiopulmonary monitoring tools and variables and is also divided into cardiac (e.g, echocardiography, heart rate, cardiac output), pulmonary (e.g, lung volume, pleural pressure, electrical impedance tomography), and combined tools such as radiology/MRI and tissue perfusion tests. The third section concerns the management and application of specific clinical problems such as pulmonary hypertension, cardiac shunts, cardiogenic shock, and ECMO with an emphasis on the physiological basics. /div Cardiopulmonary Monitoring: Basic Physiology, Tools, and Bedside Management for the Critically Ill is an essential resource for physicians, residents, fellows, medical students, and researchers in cardiology, critical care, emergency medicine, anesthesiology, and radiology.
The entire first series of the BBC family sitcom following pompous, upwardly-striving Muslim businessman Mr Khan (Adil Ray) and his hard done-by family. Living in Sparkhill, part of Birmingham's 'Balti Triangle', with his house-proud wife (Shobu Kapoor) and two rebellious daughters Shazia (Maya Sondhi) and Alia (Bhavna Limbachia), the distinctly retro, self-styled leader of the community constantly tries to get others to see the wisdom of his ways, without much success.
Praised for its concise coverage, this highly accessible monograph lays a foundation for understanding the underlying concepts of normal cardiovascular function and offers a welcome alternative to a more mechanistically oriented approach or an encyclopedic physiology text. Clear explanations, ample illustrations and engaging clinical cases and problems provide the perfect guidance for self-directed learning and prepare you to excel in clinical practice.
Although cardiac output is measured as the flow of blood from the left ventricle into the aorta, the system that controls cardiac output includes many other components besides the heart itself. The heart’s rate of output cannot exceed the rate of venous return to it, and therefore, the factors governing venous return are primarily responsible for control of output from the heart. Venous return is affected by its pressure gradient and resistance to flow throughout the vascular system. The pressure gradient for venous return is a function of several factors including the blood volume flowing through the system, the unstressed vascular volume of the circulatory system, its capacitance, mean systemic pressure, and right atrial pressure. Resistance to venous return is the sum of total vascular resistance from the aortic valve to the right atrium. The sympathetic nervous system and vasoactive circulating hormones affect short-term resistance, whereas local tissue blood flow autoregulatory mechanisms are the dominant determinants of long-term resistance to venous return. The strength of contraction of the heart responds to changes in atrial pressure driven by changes in venous return, with small changes in atrial pressure eliciting large changes in strength of contraction, as described by the Frank–Starling mechanism. In addition, the autonomic nervous system input to the heart alters myocardial pumping ability in response to cardiovascular challenges. The function of the cardiovascular system is strongly affected by the operation of the renal sodium excretion–body fluid volume–arterial pressure negative feedback system that maintains arterial blood pressure at a controlled value over long periods. The intent of this volume is to integrate the basic knowledge of these cardiovascular system components into an understanding of cardiac output regulation.

Accurate clinical observations are the key to good patient care and fundamental to nursing practice. Vital Signs for Nurses will support anyone in care delivery to enhance their skills, reflect upon their own practice and assist in their continuing professional development. This practical introductory text explores how to make assessments of heart rate, blood pressure, temperature, pain and nutrition. It also looks at issues of infection control, record-keeping and legal and ethical considerations. With case studies and examples throughout, this text will be invaluable to all healthcare assistants, student nurses, Trainee Assistant Practitioners and students on foundation degrees.
This is the first comprehensive study guide covering all aspects of pediatric critical care medicine. It fills a void that exists in learning resources currently available to pediatric critical care practitioners. The major textbooks are excellent references, but do not allow concise reading on specific topics and are not intended to act as both text and study guide. There are also several handbooks available, but these are usually written for general pediatric residents and lack the advanced physiology and pathophysiology required for the higher level pediatric critical care practitioner
