This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

The Studies in Physiology series provides a concise introduction to developments in complex areas of physiology for a wide audience. Published on behalf of the Physiology Society, Cardiovascular Regulation provides an up-to-date account of our current understanding of the control of the cardiovascular system that is not covered by existing textbooks. Both students and lecturers of cardiovascular and exercise physiology, medicine, dentistry and biomedical sciences will find this book informative and easy to read. Each chapter has numerous summary boxes. 'Essential reading' suggestions provide additional reading for undergraduates and the suggestions for 'Further reading' cover the subject to postgraduate level.

One of the most time-consuming tasks in clinical medicine is seeking the opinions of specialist colleagues. There is a pressure not only to make referrals appropriate but also to summarize the case in the language of the specialist. This book explains basic physiologic and pathophysiologic mechanisms of cardiovascular disease in a straightforward manner, gives guidelines as to when referral is appropriate, and, uniquely, explains what the specialist is likely to do. It is ideal for any hospital doctor, generalist, or even senior medical student who may need a cardiology opinion, or for that ma.

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.

The acclaimed full-color clinical manual and review of TEE --- completely updated to reflect the field’s latest breakthroughs and developments Doody's Core Titles for 2021! Clinical Manual and Review of Transesophageal Echocardiography, Third Edition is written to be the field’s go-to resource and the standard reference textbook on the topic. It offers concise yet comprehensive coverage of the key principles, concepts, and developing practice of transesophageal echocardiography. Completely updated, reorganized, and expanded, this Third Edition features a sectional format, each containing chapters that were reviewed and revised to provide a comprehensive discussion of physiology, pathophysiology, and echocardiographic approach for normal and common disease states. Where possible, important clinical information has been aligned with the principles of cardiovascular physiology and echocardiographic techniques. Narrative text, charts, videos, and graphs have been effectively integrated to provide rapid access to key clinical information for the purpose of improving clinical management. Features: Addresses all the important clinical and technical issues and major exam topics Valuable appendices detailing normal chamber dimensions and volumes; wall motion and coronary perfusion; diastolic function; native valve areas, velocities, and gradients; and measurements and calculations Contributions from leading anesthesiologists, cardiologists, and cardiothoracic surgeons A complete practice exam and chapter-ending multiple choice questions make this the perfect review for board examinations in both basic and advanced perioperative echocardiography

​There is an evident practice gap in education of general adult cardiologists on long-term management of congenital heart disease (CHD). The goal of this book is to help general cardiologists, but also pediatricians and related care providers in the management and diagnosis of adult CHD. Adult Congenital Heart Disease in Clinical Practice provides clear, practical advice on adult CHD for the busy fellow, resident and practicing clinician. It includes training and revision material to assist learning and is formatted in such a way as to provide short, concise content designed for easy recall of salient facts.
