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. Chapter 11 focuses on the hearing aids. Section II is devoted to modern medical imaging systems as computers now provide a new means for storing processing transferring and displaying images. Section III focuses on therapeutic equipment like electric stimulators used in patient care and research. Section IV focuses on special topics such as medical procedures that usually expose the patient to more hazards than the typical home or work place and the sources include air water chemicals drugs microorganisms noise electricity radiation from X-ray ultrasound microwaves and lasers etc. Glossary at the end of the text provides a quick reference to the reader.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
