Implantable Impedance Plethysmography [PDF]

Sensors, 2014
We demonstrate by theory, as well as by ex vivo and in vivo measurements that impedance plethysmography, applied extravascularly directly on large arteries, is a viable method for monitoring various cardiovascular parameters, such as blood pressure, with

Estimation of heart rate variability from finger photoplethysmography during rest, mild exercise and mild mental stress

Journal of Electrical Bioimpedance, 2021
Due to the possibilities in miniaturization and wearability, photoplethysmography (PPG) has recently gained a large interest not only for heart rate measurement, but also for estimating heart rate variability, which is derived from ECG by convention. The

Thoracoabdominal asynchrony: Two methods in healthy, COPD, and interstitial lung disease patients. [PDF]

PLoS ONE, 2017
Thoracoabdominal asynchrony is the nonparallel motion of the ribcage and abdomen. It is estimated by using respiratory inductive plethysmography and, recently, using optoelectronic plethysmography; however the agreement of measurements between these 2 ...
