Central Blood Pressure Monitoring via an Automatic Arm Cuff

Blood pressure (BP) near the heart (i.e., central BP) is clinically more relevant than BP away from the heart. But, BP from the arm is more easily measured with an automatic cuff device. A model-based method was developed to estimate central BP using a standard automatic arm cuff device. The method was initially tested in patients using invasive central BP measurements as a reference. The method achieved central BP estimation errors of 5.6-7.9 mmHg.
