| Abstract | An algorithm enabling calculation of the ankle-brachial pressure index (ABPI) was developed. ABPI relates the blood pressure in different body limbs. Using ABPI the level of vessel occlusion can be predicted and used as a simple screening method for candidates for a more thorough clinical vascular examination. To measure ABPI, the blood pressure in body limbs must be measured. In our approach, the oscillometric blood pressure measurement method was applied. It employs the usage of an inflatable cuff placed on the measured limb. The blood pressure is measured by observing the squeezed vessel pulsations caused pressure oscillations in the cuff as a function of the absolute air pressure in the cuff. First, the pressure course is preprocessed and systolic, diastolic, mean blood pressure, heart rate and channel delays are then calculated. The algorithm was developed using 59 simulated and 13 real patients-obtained pressure courses. |
