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

Differential sensitivity of impedance plethysmography and photoplethysmography sensors to temperature-induced peripheral vasoconstriction [PDF]

Scientific Reports
Impedance plethysmography (IPG) and photoplethysmography (PPG) are non-invasive techniques for measuring blood volume changes. This study investigated the differential responses of IPG and PPG to temperature-mediated vasoconstriction induced by localized

Toe digit pulsation measurement by impedance plethysmography in miniaturized devices: An early feasibility test [PDF]

Journal of Electrical Bioimpedance
This early feasibility test explores impedance plethysmography (IPG) for detecting toe pulse waves using a setup suited for miniaturized devices. Conventional tests often miss micro-circulatory impairment, which is critical for wound healing and limb ...

The Effects of Glucagon-Like Peptide-1 Receptor Agonists and Sodium-Glucose Co-Transporter-2 Inhibitors on Lean Body Mass in Humans: A Systematic Review and Meta-Analysis of Randomised Controlled Trials. [PDF]

Diabetes Metab Res Rev
ABSTRACT Aims The use of pharmacotherapies with weight loss properties for the management of obesity and chronic disease are now routinely prescribed. We investigated the evidence from randomised‐controlled trials for the effects on lean body mass of glucagon‐like peptide‐1 receptor agonists (GLP‐1RA) and sodium‐glucose co‐transporter‐2 inhibitors ...
