Bioimpedance Analysis: Basic Concepts

Journal of Renal Nutrition and Metabolism, 2023
Bioimpedance analyzers uses these differences in the electrical properties of the human body to analyze the cellular and water components. Human body acts as a semiconductor, with the various body compartments offering resistance (R) and reactance (X) to the passage of alternating current.

Bioimpedance and Bioimpedance Vector Analysis in patients with Anorexia Nervosa

European Eating Disorders Review, 2012
AbstractObjectiveThe utility of bioelectrical impedance analysis (BIA) in patients with anorexia nervosa (AN) is imperfectly defined. Furthermore, any advantage accrued by BIA with vector analysis (BIVA) is unknown.MethodWe conducted a retrospective analysis of 57 women with AN admitted to our service who underwent BIA and BIVA. Twenty‐seven women were

The Use of Bioimpedance Analysis to Evaluate Lymphedema

Annals of Plastic Surgery, 2007
Lymphedema, a chronic disfiguring condition resulting from lymphatic dysfunction or disruption, can be difficult to accurately diagnose and manage. Of particular challenge is identifying the presence of clinically significant limb swelling through simple and noninvasive methods.

Bioimpedance analysis and HIV-related fatigue

Journal of the Association of Nurses in AIDS Care, 2005
Although various physiological and psychological causes of fatigue in HIV-positive persons have been proposed, it is still not well understood. Bioimpedance analysis has proved to be an easily used, non-invasive measurement of body composition and cellular integrity.

Simulation of Bioimpedance Analysis in MATLAB

Biomedical Engineering, 2013
Technology for simulation of bioimpedance analysis is presented using mathematical and physical models of Simulink MATLAB software. The resulting virtual bioimpedance model allows dynamic and basic bioimpedance components to be simulated, thereby providing adequate models for a biological object, as well as a monitoring tract.

Bioimpedance Analysis (BIA) in Hemodialysis: Technical Aspects

The International Journal of Artificial Organs, 1995
Phase-sensitive impedance analysis in association with anthropometric parameters provides adequate body composition estimates in nephropathic subjects, with complex three-compartment modelling as a reference. Extracellular fluid shifts can be detected during ultrafiltration by phase sensitive impedance analyzers.
