We propose an ultra-convenient cuffless blood pressure (BP) monitoring approach based on the ballistocardiogram (BCG). The approach monitors BP using two mechanistically derived features in the whole-body, head-to-foot BCG: the time interval between the first and second major waves for DP, and the amplitude between the second and third major waves for pulse BP (PP; which can be added to DP to yield SP). The proposed approach can complement the conventional pulse transit time technique in two ways.
This study quantifying anatomical site variability and individual variability in the calibration term for blood pressure (BP) estimation from pulse transit time. Using and accurately calculating hydrostatic changes in BP within the individual may be one method to increase accuracy of the calibration term.
Cardiovascular disease (CVD) affects over one third of the U.S. population and is the current leading cause of death. Many key cardiovascular parameters such as the heart rate, stroke volume, pre-ejection period (PEP), and pulse transit time (PTT) have valuable applications in the field of CVD monitoring.
