Book Description
In summary, the mechanical integration of ventricular and pulmonary actions is determined by a number of mechanisms including airway pressure, pleural and pericardial pressure, state of the interventricular septum, and others. After this brief review of essential features, we may discuss some aspects of the interactions between heart and lung function. Influence of Intrathoracic Pressure: The Importance of Transmural Pressure It is established that blood pressure, volume and flow rates in the lesser circula tion change during each respiratory cycle. The effects of intrathoracic (Pit) and pleural (P pi) pressures, and lung volumes, were recently described in terms of ventricular preload and afterload during normal breathing, hyperventilation, and the Valsalva and Muller maneuvers [4, 7, 8]. Still, many aspects remain unsettled, mainly because of technical difficulties related to the simultaneous recording of floating respiratory and circulatory events in the intact animal or in man [9]. Some confusion arises from the clinicians' unawareness of the role played by the transmural pressure (Ptm), being the pressure gradient between the lumen of a vessel or heart chamber and the surrounding tissues (Pit for the pulmonary arteries and veins, and Ppe for the heart). Yet, an undetected change of Plm may modify vascular caliber and resistance in the pulmonary district, regardless of any changes in vasomotor activity. Consequently, a change of vascular resistance concomitant with a change of Ptm is not a reliable index of pulmonary vasomo tricity.

Book Description
Now in paperback, the second edition of the Oxford Textbook of Critical Care is a comprehensive multi-disciplinary text covering all aspects of adult intensive care management. Uniquely this text takes a problem-orientated approach providing a key resource for daily clinical issues in the intensive care unit. The text is organized into short topics allowing readers to rapidly access authoritative information on specific clinical problems. Each topic refers to basic physiological principles and provides up-to-date treatment advice supported by references to the most vital literature. Where international differences exist in clinical practice, authors cover alternative views. Key messages summarise each topic in order to aid quick review and decision making. Edited and written by an international group of recognized experts from many disciplines, the second edition of the Oxford Textbook of Critical Careprovides an up-to-date reference that is relevant for intensive care units and emergency departments globally. This volume is the definitive text for all health care providers, including physicians, nurses, respiratory therapists, and other allied health professionals who take care of critically ill patients.

Book Description
The ESC Textbook of Intensive and Acute Cardiovascular Care is the official textbook of the Acute Cardiovascular Care Association (ACVC) of the ESC. Cardiovascular diseases (CVDs) are a major cause of premature death worldwide and a cause of loss of disability-adjusted life years. For most types of CVD early diagnosis and intervention are independent drivers of patient outcome. Clinicians must be properly trained and centres appropriately equipped in order to deal with these critically ill cardiac patients. This new updated edition of the textbook continues to comprehensively approach all the different issues relating to intensive and acute cardiovascular care and addresses all those involved in intensive and acute cardiac care, not only cardiologists but also critical care specialists, emergency physicians and healthcare professionals. The chapters cover the various acute cardiovascular diseases that need high quality intensive treatment as well as organisational issues, cooperation among professionals, and interaction with other specialities in medicine. SECTION 1 focusses on the definition, structure, organisation and function of ICCU's, ethical issues and quality of care. SECTION 2 addresses the pre-hospital and immediate in-hospital (ED) emergency cardiac care. SECTIONS 3-5 discuss patient monitoring, diagnosis and specific procedures. Acute coronary syndromes (ACS), acute decompensated heart failure (ADHF), and serious arrhythmias form SECTIONS 6-8. The main other cardiovascular acute conditions are grouped in SECTION 9. Finally SECTION 10 is dedicated to the many concomitant acute non-cardiovascular conditions that contribute to the patients' case mix in ICCU. This edition includes new chapters such as low cardiac output states and cardiogenic shock, and pacemaker and ICDs: troubleshooting and chapters have been extensively revised. Purchasers of the print edition will also receive an access code to access the online version of the textbook which includes additional figures, tables, and videos to better to better illustrate diagnostic and therapeutic techniques and procedures in IACC. The third edition of the ESC Textbook of Intensive and Acute Cardiovascular Care will establish a common basis of knowledge and a uniform and improved quality of care across the field.

Book Description
For many years, there has been a great deal of work done on chronic congestive heart failure while acute heart failure has been considered a difficult to handle and hopeless syndrome. However, in recent years acute heart failure has become a growing area of study and this is the first book to cover extensively the diagnosis and management of this complex condition. The book reflects the considerable amounts of new data reported and many new concepts which have been proposed in the last 3-4 years looking at the epidemiology, diagnostic and treatment of acute heart failure.

Book Description
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.

Book Description
This book offers readers a better understanding of how to perform echocardiography in their daily intensive care unit (ICU) work. With numerous practical examples highlighting the indices and hemodynamic monitoring profiles that physicians could encounter, it considers echocardiography not merely as a simple imaging technique, but as a practical diagnostic and hemodynamic monitoring tool. The booklet is richly illustrated with figures explaining how to perform echo, and includes numerous tables, simple equations and normal and abnormal values. Echocardiography in ICU, a pocket guide written by the leading international experts in the field, is an excellent source of information and guidance for all residents and physicians working in ICU, emergency medicine, anesthesia and cardiology as well.
