A Cuffless Blood Pressure Measurement Based on the Impedance Plethysmography Technique
In the last decade, cuffless blood pressure measurement technology has been widely studied because it could be applied to a wearable apparatus. Electrocardiography (ECG), photo-plethysmography (PPG), and phonocardiography are always used to detect the pulse transit time (PTT) because the changed tendencies of the PTT and blood pressure have a negative relationship. In this study, the PPG signal...
متن کاملContinuous cuffless arterial blood pressure measurement based on PPG quality assessment
The continuous cuffless arterial blood pressure (ABP) can be calculated by the pulse transit velocity. Its accuracy is significantly influenced by the selection of the photoplethysmography (PPG) feature points. In this paper, we designed an assessment function to calculate the quality of PPG. The quality index indicates the reliability of PPG and helps to determine proper feature points. Kalman...
متن کاملComparison of Various Blood Pressure Measurement Techniques with Standard Office Based Blood Pressure Mesurement
Introduction: In order to control Hypertension, it is necessary to understand the methods of blood pressure measurement. Recent guidelines emphasize on employing appropriate blood pressure measurement techniques and white coat hypertension. Definition and methods of blood pressure measurement have changed in the American guideline based on SPRINT trial (Systolic Blood Pressure Intervention Tria...
متن کاملAn Eigenvalue Based Acoustic Impedance Measurement Technique
A method is developed for measuring acoustic impedance. The method employs a one-dimensional tube or duct with excitation at one end and an unknown acoustic impedance at the termination end. Microphones placed in the tube are then employed to measure the frequency response of the system from which acoustic impedance of the end is calculated. This method uses fixed instrumentation and takes adva...
متن کاملCuffless Blood Pressure Estimation Based on Data-Oriented Continuous Health Monitoring System
Measuring blood pressure continuously helps monitor health and also prevent lifestyle related diseases to extend the expectancy of healthy life. Blood pressure, which is nowadays used for monitoring patient, is one of the most useful indexes for prevention of lifestyle related diseases such as hypertension. However, continuously monitoring the blood pressure is unrealistic because of discomfort...
