Abstract :
We developed a finger type blood pressure measurement system using a volume oscillometric algorithm. The digital envelope detection filter (EDF) method was applied to volume oscillometric signals which were acquired from an air-filled occlusive finger cuff. In the case of using the EDF, we could reduce the difference error and standard deviation by 30-40%.
