Technology of two-dimensional bioimpedance analysis of the human body composition

Journal of Electrical Bioimpedance, 2021
The BIA primary result sheets as a rule contain one-dimensional graphical scales with a selected area of normal values. In 1994, Piccoli et al. proposed BIVA, an alternative form of BIA data presentation, where two bioimpedance parameters are considered ...

Bioelectrical impedance vector analysis (BIVA) in stable preterm newborns [PDF]

Jornal de Pediatria, 2012
To observe the behavior of the plotted vectors on the RXc (R - resistance - and Xc - reactance corrected for body height/length) graph through bioelectrical impedance analysis (BIVA) and phase angle (PA) values in stable premature infants, considering the hypothesis that preterm infants present vector behavior on BIVA suggestive of less total body ...

ConsensusPaper on the use of BIVA (BioelectricalImpedanceVector Analysis) in medicine for the managment of bodyhydratation.

, 2011
Hydration status assessment remains a challenge overall in sub- clinical hyper/dehydration status. Biompedance Vector Analysis (BIVA) is a non invasive technique to estimate body mass and water composition by bioelectrical impedance measurements, resistance and reactance.

Body composition analysis in patients with acute heart failure: the Scale Heart Failure trial

ESC Heart Failure, 2021
Aims In this study, we aimed to investigate whether body composition analysis (BCA) derived from bioelectrical impedance vector analysis (BIVA) could be used to monitor the hydration status of patients with acute heart failure (AHF) during intensified ...

A practical guide to bioelectrical impedance analysis using the example of chronic obstructive pulmonary disease

Nutrition Journal, 2011
Bioelectrical impedance analysis (BIA) is a simple, inexpensive, quick and non-invasive technique for measuring body composition. The clinical benefit of BIA can be further enhanced by combining it with bioelectrical impedance vector analysis (BIVA ...

BIVAS: A Scalable Bayesian Method for Bi-Level Variable Selection With Applications [PDF]

Journal of Computational and Graphical Statistics, 2019
In this paper, we consider a Bayesian bi-level variable selection problem in high-dimensional regressions. In many practical situations, it is natural to assign group membership to each predictor. Examples include that genetic variants can be grouped at the gene level and a covariate from different tasks naturally forms a group. Thus, it is of interest

Bioelectrical Impedance Vector Analysis (BIVA) for the monitoring of body composition in pregnancy

European Journal of Clinical Nutrition, 2021
During pregnancy, body composition alterations can be considered as markers of complications and in this context, a non-invasive and low-cost method such as Bioelectrical Impedance Vector Analysis (BIVA), can be employed to monitor such changes. This study aimed at identifying body compartments trend during physiological pregnancy.Classic and specific ...
