A survey on investigation of vital human parameters from photoplethsmography signal to predict the risk of cardiovascular diseases

Cardiovascular disease (CVD) is one of the major cause of death in the recent days. The diabetes patients are mostly affected by Cardiovascular disease. An abnormal respiratory rate, heart rate, blood pressure are habitually fundamental sign of CVD. The occurrence of CVD leads to sudden death. So it is need to predict the CVD earlier. The best method of prediction is by using PPG signal. The measurement of blood pressure, heart rate, respiratory, pulse rate using Photoplethysmography (PPG) provides the health condition in daily life and also ensure the risky disease. This study mainly focusing to measure the health vital parameters using PPG signal.
