Pulmonary Gas Exchange, Volume I: Ventilation, Blood Flow, and Diffusion considers the mechanisms of gas exchange in the lung. This volume is composed of nine chapters that particularly discuss the roles of ventilation, blood flow, and diffusion in pulmonary gas exchange. The opening chapter briefly traces the history of the chemistry and physics of pulmonary gas exchange. The next two chapters are devoted to the momentous developments that took place near the end of the Second World War advances which established the modern basis of gas. The remaining chapters describe the mechanism of gas exchange in the alveoli, how it crosses the blood-gas barrier, and the way in which ventilation-perfusion relationships determine the efficiency of exchange. This book will be of great benefit to pulmonologists and researchers in the biomedical field.
