Physical model-based oscillometric BP estimation methods. BP is estimated via subject-specific physical modeling rather than population-based formulas. In this way, BP may be estimated more accurately than the fixed-ratios and other existing methods. (a) Physical model of oscillometry [7]. (b) Method 1 estimates BP values from the oscillometric cuff pressure waveform and a priori measurements on the employed cuff [8]. (c) Method 2 estimates BP values from only the oscillometric cuff pressure waveform without requiring detailed knowledge of the cuff properties.
