Book Description
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.

Book Description
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.

Book Description
On 15 November 1997, the first international symposium "Neural and Chemical Control of Breathing: Pharmacological and Clinical Aspects" was held at Leiden University Medical Center on the occasion of the retirement of one of the members of the Control of Breathing Research Group of the Departments of Physiology and Anesthesiology, Dr. Aad Berkenbosch. Among others, Dr. Berkenbosch, played an important role in this research group, which made a large and significant contribution to scientific research on the regulation of breathing. This book presents the proceedings of that meeting together with papers of several authors who have strong bonds with the Leiden Departments of Physiology and Anesthesiology. All studies represent state of the art work on the subject of respiratory control and cardiovascular medicine, with emphasis on the physiological, pharmacological and anesthesiological aspects of both fields. The book is divided in several sections: Oxygen Physiology. Prof. John Severinghaus presents among other things his ideas on oxygen sensing and high altitude related diseases. Prof. Honda gives results from studies in a unique set of subjects without carotid bodies. The findings of Honda's group support the idea that an intact hypoxic drive from the carotid bodies is necessary for the generation of central hypoxic depression. Dr. Hans van Beek discusses the effects of hypoxia and hypercapnia on cardiac contractility in animal models. Prof. Oeseburg demonstrates the feasibility of Near Infra Red Oximetry for monitoring tissue oxygenation in patients. Central Chemoreception.

Dr. Fenn had agreed to be baric study. honorary conference chairman of this meet The study of muscle contraction started ing, but was unable to attend because of the in 1922 when Fenn became the first American to work in A.

Book Description
In recent years capnography has gained a foothold in the medical field and is fast becoming a standard of care in anaesthesiology and critical care medicine. In addition, newer applications have emerged which have expanded the utility of capnographs in a number of medical disciplines. This new edition of the definitive text on capnography reviews every aspect of this valuable diagnostic technique. An introductory section summarises the basic physiology of carbon dioxide generation and transport in the body. A technical section describes how the instruments work, and a comprehensive clinical section reviews the use of capnography to diagnose a wide range of clinical disorders. Edited by the world experts in the technique, and with over 40 specialist contributors, Capnography, second edition, is the most comprehensive review available on the application of capnography in health care.

Book Description
This book represents an updated review of the physiology of the carotid body chemoreceptors. It contains results in the topics at the frontiers of future developments in O2-sensing in chemoreceptor cells. Additionally, this volume provides data from studies carried out in other O2-sensing tissues including pulmonary vasculature and erythropoietin producing cells. It is a prime source of information and a guideline for arterial chemoreception researchers.
