A Cuffless Blood Pressure Measurement Based on the Impedance Plethysmography Technique

Sensors, 2017
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 ...

Limitations of Electric Impedance Plethysmography [PDF]

Circulation Research, 1954
Electric impedance plethysmography has been offered as a substitute for mechanical plethysmography and would be particularly suitable for regions in which the mechanical method cannot be applied. A comparative investigation of mechanical and impedance plethysmograms, taken simultaneously from a finger or a forearm, revealed that, while the normal ...

Intelligent Bio-Impedance System for Personalized Continuous Blood Pressure Measurement

Biosensors, 2022
Continuous blood pressure (BP) measurement is crucial for long-term cardiovascular monitoring, especially for prompt hypertension detection. However, most of the continuous BP measurements rely on the pulse transit time (PTT) from multiple-channel ...
