Abstract
OBJECTIVE
This paper proposes an unobtrusive blood pressure (BP) measurement system design with motion artifact (MA) compensation strategy as a potential surrogate to the traditional cuff-based sphygmomanometer for self-monitoring in less restricted environment. Approach: A dual-channel photoplethysmographic signal acquisition system is designed and implemented for the cuff-less BP measurement based on peripheral pulse transit time (PPTT) acquired from the forearm and wrist. Comprised of motion decision, singular spectrum analysis, PPTT calculation and BP measurement, a novel approach is proposed to realize BP measurement with suppressing MA interference. Main results: Compared with reference BP recorded by a cuff-based sphygmomanometer, our preliminary examinations on 30 subjects found that the correlation coefficients for systolic BP estimation and diastolic BP estimation were 0.75 and 0.78, and the mean absolute differences were 7.61 mmHg and 6.82 mmHg, respectively. Meanwhile, the proposed approach was compared with other most widely-used pulse transit time (PTT) measuring methods and BP-PTT models. All the results indicated that our work was highly effective on the BP measurement. Significance: The proposed system and approach make remarkable progress in cuff-less BP measurement with MA removal, and have great potential values in wearable applications without environmental restrictions.
