Patient monitoring is to have a quantitative assessment of the important physiological variables of patients during critical periods of biological functions. For diagnostic and research purposes, it is necessary to know their actual value or trend of change. Telemonitoring systems are used for measuring continuously or at regular intervals, automatically, the values of the patient's important physiological parameters. Telemedicine system based on embedded computer deals with real time continuous monitoring and recording of parameters like body temperature, electrocardiogram, blood pressure and respiration as well as their analysis. With the advent of computerization in biomedical field, this dissertation has very wide scope, due to the computerized data acquisition, monitoring and control incorporated in it. It reduces the workload of doctors and also gives more accurate results in patients survival.
