Features of Microprocessor-Based ECG Systems
Microprocessors have been used in electrocardiographs to obtain certain advanced features like the elimination of artefacts, baseline shifting, and so forth using software techniques. In this article, we look at some of the key features of microprocessor-based ECG systems as follows: Microprocessor-based ECG machines can perform self-testing each time they are switched on. They are…

The Applications of Microcontrollers in Medical Instrumentation
A microcontroller is a self-contained device that includes a CPU, ROM, RAM, clock circuity and I/O circuity on a single integrated circuit (IC) package. A microcontroller does not require accompanying support chips for its operation as conventional microprocessors do. A microcontroller often replace analog circuits by performing the signal processing functions of a comparator, limiter,…

3 Roles Played by Smart Sensors in Biomedical Instrumentation
A smart medical sensor is a device that detects a physiological variable and employs built-in computing capabilities to perform predefined function upon detection of this specific variable and then processes the data before passing it on to the next component in the measurement system. Smart sensors have tight coupling between sensing and computing elements hence…

Key Features and Applications of Telemedicine
Telemedicine is the use of telecommunication and computer technologies to deliver health care from one location to another. Telemedicine employs modern information technology to deliver timely health services to those who need it by electronic transmission of the necessary expertise and information among geographically dispersed parties. Physicians, laboratories and patients can be the distant parties.…

Biotelemetry and How it is Applied in Medical Field
Biotelemetry is the process which the measurement of biological parameters is done over a distance. This involves transmitting the bioelectrical and physiological data from the point of generation i.e. a patient located away from the hospital to the point of reception (hospital). The biological data are put in a suitable form to be transmitted by…

The application of Microprocessors in Medical Instrumentation
What is a Microprocessor? A microprocessor is a computer processor that incorporates the functions of a central processing unit (CPU) on a single integrated circuit (IC) or sometimes up to 8 integrated circuits. A microprocessor is programmable, multipurpose, clock-driven, register based electronic device that reads binary instructions from a storage device called memory, accepts binary…
