Abstract:
Novel blood pressure (BP) monitoring device focused on portability was studied preliminarily. Electrocardiogram (ECG) and photoplethysmogram (PPG) was measured and pulse arrival time (PAT) was computed from these signals. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) showed a clear correlation with PAT. BP estimation model was constructed based on this result and verified by means of leave-one-out cross-validation (LOOCV). Estimated SBP, DBP were involved in two standards of means of original data. This device is expected to be useful to the people who want to monitor BP at any time and space.
