The arrow of bioimpedance [PDF]

Kidney International, 2006
The value of bioimpedance in hemodialysis remains under debate. However, when appropriately used, bioimpedance can provide measures of body hydration characterized by a small error, a high sensitivity to changes in water volume, and, above all, a linear relationship over a wide range of volume changes. These features make it very useful to measure body

Optimal designs for studying bioimpedance

Physiological Measurement, 2007
D-optimal designs for nonlinear fixed and mixed effects models are explored, and the theory is applied to the measurement and analysis of bioelectrical impedance. Bioimpedance is known to vary more at extreme frequencies than others. D-optimal designs that account for this variation, and also possible mis-specification of initial parameter estimates ...

Bioimpedance norms for the hemodialysis population

Kidney International, 1997
More than 3,000 hemodialysis patients were examined with single-frequency bioelectrical impedance analysis (BIA). Distributions of resistance, reactance, phase angle (PA), and estimates of total body water (TBW) and body cell mass (BCM) by BIA were determined, and compared with traditional laboratory markers of nutritional status.

Fundamentals of Skin Bioimpedances

Advanced Materials, 2023
AbstractThe bioimpedances of tissues beyond the stratum corneum, which is the outermost layer of skin, contain crucial clinical information. Nevertheless, bioimpedance measurements of both the viable skin and the adipose tissue are not widely used, mainly because of the complex multilayered skin structure and the electrically insulating nature of the ...

Effects of empagliflozin on fluid overload, weight and blood pressure in chronic kidney disease

, 2023
BACKGROUND: Chronic kidney disease (CKD) is associated with fluid excess which can be estimated by bioimpedance spectroscopy. We aimed to assess effects of sodium glucose co-transporter 2 inhibition on bioimpedance-derived “Fluid Overload” and adiposity ...

The Russian bioimpedance database: an update

Journal of Electrical Bioimpedance, 2022
Abstract Extensive bioelectrical impedance analysis (BIA) data have the potential of health monitoring and the assessment of health risks at the population level. The importance of BIA data lies in their availability and abundance for many countries. In Russia, mass BIA data are generated by the national network of health centers (HCs)
