Cuff-Less Blood Pressure Estimation Using Only the Photoplethysmography Signal in the Frequency Domain

Blood Pressure (BP) is the result of cardiovascular activity and photoplethysmography (PPG) signal is good indication of the mechanical activity of the heart. Many studies have examined the relationship between PPG signal and BP. Also, results of BP estimation have reported by using the only PPG signal. This paper presents new algorithm for estimating BP using only the PPG signal, without any cuff and calibration. new feature vector extraction method in the frequency domain, called the frequency whole-based method, is proposed. According to the British Hypertension Society (BHS) standards, the proposed algorithm achieves grade for the Diastolic Blood Pressure (DBP) and grade for Mean Atrial Blood Pressure (MAP) estimations on MIMIC II dataset.
