Bioelectrical impedance vector analysis to evaluate relative hydration status

Pediatric Nephrology, 2010
The objective was to present our clinical experience with bioelectrical impedance vector analysis (BIVA). Forty-six patients with chronic kidney disease (CKD) without oedema, 21 oedematous nephrotic children and 15 in remission from nephrotic syndrome were studied. The age range was 2-14 years.

Bioelectrical impedance vector analysis in COPD patients

Proceedings of the 25th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (IEEE Cat. No.03CH37439), 2004
In this preliminary study, the bioelectrical impedance vector analysis (BIVA) method has been validated in a group of chronic obstructive pulmonary disease (COPD) patients. Z/H mean vector between healthy controls (C), COPD patients with low FFM (FFM/sub L/ and COPD patients with normal FFM (FFM/sub n/) was compared using the tolerance ellipses from ...

Bioelectrical phase angle and impedance vector analysis – Clinical relevance and applicability of impedance parameters

Clinical Nutrition, 2012
The use of phase angle (PhA) and raw parameters of bioelectrical impedance analysis (BIA) has gained attention as alternative to conventional error-prone calculation of body composition in disease. This review investigates the clinical relevance and applicability of PhA and Bioelectrical Impedance Vector Analysis (BIVA) which uses the plot of ...

Impedance vector distribution by body mass index and conventional bioelectrical impedance analysis in obese women

Nutrition, Metabolism and Cardiovascular Diseases, 2003
To compare the body fluid status assessments provided by conventional bioelectrical impedance analysis (BIA) and vector BIA in moderate and severe obesity.We studied 516 normotensive Caucasian women (mean age: 48 +/- 9.2 years), who were age-matched and divided into four groups on the basis of their body mass index (BMI): 99 normal weight women with a ...

Differentiation of Cardiac and Noncardiac Dyspnea Using Bioelectrical Impedance Vector Analysis (BIVA)

Journal of Cardiac Failure, 2012
There is no gold standard for the differential diagnosis of acute dyspnea despite the usefulness of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and lung ultrasound. No study has evaluated the contribution of bioelectrical impedance vector analysis (BIVA) in discriminating between cardiac and noncardiac dyspnea.

Body hydration assessment using bioelectrical impedance vector analysis in neurologically impaired children

European Journal of Clinical Nutrition, 2019
Dehydration is common and frequently under-diagnosed in chronic malnourished children, leading to life-threatening conditions. In this pilot study we applied bioimpedance vector analysis (BIVA) to determine hydration status in 52 neurologically impaired (NI) paediatric patients (14.08 ± 5.32).

Bioelectrical impedance vector analysis in haemodialysis patients: relation between oedema and mortality

Physiological Measurement, 2004
In this work, bioelectrical impedance vector analysis (BIVA) method is used in a sample of haemodialysis patients in stable (without oedema) and critical (hyperhydrated and malnutrition) states, in order to establish the relation between hyperhydration (oedema) and mortality.

Analysis of concordance between the bioelectrical impedance vector analysis and the bioelectrical impedance spectroscopy in haemodialysis patients.

Nefrologia : publicacion oficial de la Sociedad Espanola Nefrologia, 2012
The values of body composition provided by the two most commonly used bioelectrical impedance systems in Spain, single-frequency bioelectrical impedance vector analysis (SF-BIVA) and multi-frequency bioelectrical impedance spectroscopy (MF-BIS) are different and not comparable.Analyse whether the inter-method variability is due to bioelectrical ...

The implications of bioelectrical impedance vector analysis in older adults with hip fractures

Maturitas
This study used bioelectrical impedance vector analysis to assess body composition in older adults with hip fractures, comparing results with reference populations.This cross-sectional study included patients aged 65 years or more who had undergone surgery for hip fracture and baseline bioelectrical impedance analysis at 50 kHz.

Use of Bioelectrical Impedance Vector Analysis in Dyspneic patients

2016
In patients presenting to Emergency Department with Shortness of Breath a fast diagnosis distinguishing between lung or cardiac diseases is mandatory.Quantitative assessment of congestion could be useful in the management of acute heart failure (AHF) patients.
