Beschreibung
Analysis of blood gas can be a daunting task, but it is still one of the most helpful laboratory tests in managing respiratory and metabolic disorders. Busy medical students have struggled ineffectively with Hasselbach’s modification of the Henderson equation, been torn between the Copenhagen and the Boston schools of thought; and lately, been confronted with the radically different strong-ion approach.
In modern medical practice, the health provider’s time is precious, stressing the importance of retaining focus on those aspects of clinical medicine that truly matter. It makes sense to adopt an ‘algorithmic’ approach to studying topics that are often harder to understand, such as those rooted in clinical physiology. This book is therefore set out in the form of a logical sequence of flow charts, introducing and gradually building upon the underlying concepts and enabling greater opportunity to memorize individual concepts. It enables medical students, residents, nurses and respiratory care and intensive care practitioners to grasp the principles underlying respiratory and acid-base physiology quickly and to apply the concepts effectively in clinical decision making. To facilitate this, almost every section contained within has been designed to fit onto a single page.

Blood gas analysis has become the ‘‘. . . single most helpful laboratory test in managing respiratory and metabolic dis- ders. (It is). . . imperative to consider an ABG for virtually any symptom. . . , sign. . . , or scenario. . . that occurs in a clinical 1 setting, whether it be the clinic, hospital, or ICU. ’’ For the uninitiated, the analysis of blood gas can be a daunting task. Hapless medical students, badly constrained for time, have struggled ineffectively with Hasselbach’s m- ification of the Henderson equation; been torn between the Copenhagen and the Boston schools of thought; and lately, been confronted with the radically different strong-ion approach of Peter Stewart. In the modern medical practice, the multi-tasking health provider’s time has become precious—and his attention span short. It is therefore important to retain focus on those aspects of clinical medicine that truly matter. In the handling of those subjects rooted in clinical physiology (and therefore predic- bly difficult to understand), it makes perfect sense, in my opinion, to adopt an ‘algorithmic’ approach. A picture can say a thousand words; a well constructed algorithm can save at least a hundred—not to say, much precious time—and make for clarity of thinking. I have personally found this method 1 Canham, EM, Beuther, DA, Interpreting Arterial Blood Gases, PCCU on line, Chest vii viii Preface relatively painless—and easy to assimilate. The book is set out in the form of flow charts in logical sequence, introducing and gradually building upon the underlying concepts.
Book is composed almost exclusively of flow-diagrams and pathways: this makes it reader friendly Focuses on the issues of clinical importance, and excludes issues that are of marginal relevance for the clinician Written with the awareness that medical personnel practising in ICUs are time-constrained: this book should be capable of being read rapidly Clear and concise explanations are provided about the mechanisms operative in health and disease

From the reviews:
"This is the first edition of a single author monograph describing the physiology of respiration and acid-base changes, diagnostic tests for evaluation, and their interpretation. … Medical students, postgraduate trainees, and their teachers are an appropriate audience for this work … . This is a unique, cohesive presentation which assembles not only a clinical strategy but a physiologic rationale." (David J. Dries, Doody’s Review Service, April, 2009)
