A Baseline-Tracking Single-Channel I/Q Impedance Plethysmogram IC for Neckband-Based Blood Pressure and Cardiovascular Monitoring

IEEE Journal of Solid-State Circuits, 2023
An impedance plethysmogram (IPG) IC with wide-range fine baseline tracking capability is proposed to provide continuous blood pressure (BP) and cardiovascular monitoring just by wearing a neckband wearable device. For the baseline tracking, a mixed-mode baseline cancellation (MM-BC) scheme is proposed to achieve wide dynamic range (DR) and high SNR ...

Evaluation of the theory of cardiac-output computation from transthoracic impedance plethysmogram

Medical & Biological Engineering & Computing, 1977
To analyse the limit of the stimation of stroke volume by thoracic impedance plethysmography (SVz), we considered an elastic tube forced with a trapezoidal flow input as a model of the aorta, and, based on Kubicek's equation, the volume input (SVa) was related to its impedance change via the model system parameters such as elasticity, fiuid inertia ...

Pulse arrival time estimation from the impedance plethysmogram obtained with a handheld device

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
This paper describes a novel method to estimate pulse arrival time (PAT) from the electrocardiogram (ECG) and the impedance plethysmogram (TPG) obtained by using a compact and easy-to-use handheld device with only four electrodes. A proof-of-concept has been carried out where PAT values obtained with the proposed device have been compared to PAT values
