Book Description
The lung receives the entire cardiac output from the right heart and must load oxygen onto and unload carbon dioxide from perfusing blood in the correct amounts to meet the metabolic needs of the body. It does so through the process of passive diffusion. Effective diffusion is accomplished by intricate parallel structures of airways and blood vessels designed to bring ventilation and perfusion together in an appropriate ratio in the same place and at the same time. Gas exchange is determined by the ventilation-perfusion ratio in each of the gas exchange units of the lung. In the normal lung ventilation and perfusion are well matched, and the ventilation-perfusion ratio is remarkably uniform among lung units, such that the partial pressure of oxygen in the blood leaving the pulmonary capillaries is less than 10 Torr lower than that in the alveolar space. In disease, the disruption to ventilation-perfusion matching and to diffusional transport may result in inefficient gas exchange and arterial hypoxemia. This volume covers the basics of pulmonary gas exchange, providing a central understanding of the processes involved, the interactions between the components upon which gas exchange depends, and basic equations of the process.

Book Description
The Multiple Inert Gas Elimination Technique (MIGET) is a complex methodology involving specialized gas chromatography and sophisticated mathematics developed in the early 1970’s. Essentially, nobody possesses knowledge of all its elements except for its original developers, and while some practical and theoretical aspects have been published over the years, none have included the level of detail that would be necessary for a potential user to adopt and understand the technique easily. This book is unique in providing a highly detailed, comprehensive technical description of the theory and practice underlying the MIGET to help potential users set up the method and solve problems they may encounter. But it is much more than a reference manual – it is a substantial physiological and mathematical treatise in its own right. It also has a wide applicability – there is extensive discussion of the common biological problem of quantitative inference. The authors took measured whole-lung gas exchange variables, and used mathematical procedures to infer the distribution of ventilation and blood flow from this data. In so doing, they developed novel approaches to answer the question: What are the limits to what can be concluded when inferring the inner workings from the “black box” behavior of a system? The book details the approaches developed, which can be generalized to other similar distributed functions within tissues and organs. They involve engineering approaches such as linear and quadratic programming, and uniquely use mathematical tools with biological constraints to obtain as much information as possible about a “black box” system. Lastly, the book summarizes the hundreds of research papers published by a number of groups over the decades in a way never before attempted in order to marshal the world’s literature on the topic and to provide in one place the wealth of important discoveries, both physiological a nd clinical, enabled by the technique.

Book Description
Present-day respiratory physiology stems largely from the explosion of ideas which took place during and after World War II. A number of the major players are still active, but the opportunity to prepare a personal history of this branch of medicine will soon be lost. In a sense then, this book offers an exceptional, even unique, opportunity. We are offered a first-hand chronicle of the advancements made in respiratory physiology in the course of this century by one of the principal figures in the field. The volume covers every aspect of the evolution of this important area of knowledge: morphology, gas exchange and blood flow, mechanics, control of ventillation, and comparative physiology. Some of the chapters are personal accounts of the development of respiratory physiology as observed by the author. It is hoped that what is lost in objectivity by this approach is more than made up by the captivating insights provided by the author into the process of scientific research and discovery.

Book Description
This volume records the papers presented in Chieti, Italy, at the 1991 meeting of the International Society for Arterial Chemoreception (ISAC). This was the eleventh of a series of assemblies held since 1959. This field of research, which examines the critical function and mechanisms of O and pHIPC0 sensitive cells in 2 2 the body, is unique in that it encompasses diverse biological and medical areas. The reader of this book will note chapters concerning modem techniques like in situ hybridization; analysis of cell membrane channels and intracellular ion movements; immunohistochemistry of peptides, hormones, and the corresponding receptors of chemoreceptor cells; and systemic analysis of reflex pathways involving chemoreceptor cells and their meaning in health and disease. This broad spectrum will appeal to readers interested in the chemoreceptor field, as well as young scientists seeking a scientific field where not only structural analysis but also a sense for functional connections is required. In recognition of the importance of the contribution of a new scientific generation to this field, ISAC awarded the prestigious F. de Castro-C. Heymans E. Neil prize to A. G6rlach, a young scientist. Also at this meeting, the Ferdinando Data Foundation Award, for helping scientists from non-developed countries to pursue their interest in chemoreception, was initiated. ISAC held plenary lectures in honor of C. Eyzaguirre and R. Forster, both of whom have contributed greatly to research in the chemoreceptor field.
