Systolic blood pressure classification

To classify systolic, mean and diastolic blood pressure using the oscillometric method heavily depends on the computational algorithms. Generally, the algorithms aim at extracting some parameters such as height, ratios of the pulses at certain pressure levels, which are obtained from the cuff pressure. These parameters can be used to form profiles to attribute to blood pressures. Our algorithms are based on fuzzy sets, whose membership functions are determined by using neural networks. We further employ Gram-Schmidt orthogonal transformation to select appropriate features for classification. The effectiveness of neural network solution to systolic blood pressure classification is the focus of this paper.
