Recent advances in the field of biomedical sciences have been fuelled by the development of electronic equipment and instruments with versatile capabilities and applications.This textbook is an essential reading for students teachers professionals electronics and instrumentation engineers researchers involved with study and research in life sciences microbiology biotechnology and biochemical engineering and medical institutes and hospitals. All the essential and relevant topics have been covered in a cogent and lucid style to help the reader grasp the information quickly and easily. A large number of diagrams figures and tables are given to supplement the text which is divided into four sections. Section I deals with measuring recording and monitoring instruments. Chapter 1 is devoted to the fundamentals of medical instrumentation. Chapter 2 concentrates on bioelectric signals and electrodes. Chapter 3 deals with biomedical sensors which are used in clinical medicine and biological research for measuring a wide range of physiological variables followed by Chapter 4 which focuses on biopotential amplifiers. Chapter 5 is devoted to biomedical recorders such as ECG and EEG (electroencephalograph) and various others and Chapter 6 deals with the various types of patient monitors. Chapter 7 covers the techniques and instrumentation for monitoring physiological data by telemetry and Chapter 8 is devoted to cardiac output measurement. Chapter 9 concentrates on non-invasive optical monitoring. Clinical laboratory is responsible for analysing patient specimens in the diagnosis of disease and to evaluate the effectiveness of therapy and thus Chapter 10 deals with clinical laboratory instrumentation.
