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.

Fourier Analysis of Human Finger Bioimpedance Variances

Bulletin of Experimental Biology and Medicine, 2010
Fourier analysis was employed to determine the amplitudes of spectrum components of small variations of electrical resistance (bioimpedance) in human finger recorded using an original hardware-software complex. It revealed periodic bioimpedance oscillations at the frequencies of heartbeats, respiration, and Mayer wave (0.1 Hz).

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.

Liver Cancer Analysis Using Bioimpedance

2015
In this work the impedance analysis is used in order to determinate differences between tumor and unaltered liver tissue. The electrical characterization of tissues at 10 to 200 KHz is obtained by the four electrode measurement method. The difference between the tissues is determined by phase angle measured at 50 KHz.

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.

Hydration status assessed by multi-frequency bioimpedance analysis

Applied Radiation and Isotopes, 1998
Hydration status in human subjects can be assessed by multifrequency bioimpedance analysis (MFBIA) which uses the higher conductivity of water to determine its volume. From the resistance values at low and high frequencies, the extracellular water (ECW) and the total body water (TBW) are derived, respectively.

Clinical utility of bioimpedance analysis in liver cirrhosis

Journal of Hepato-Biliary-Pancreatic Sciences, 2017
AbstractBackgroundThe objective of the present study was to examine the impact of muscle mass depletion (MMD) as determined by data in bioimpedance analysis (BIA) in liver cirrhosis (LC) patients (n = 382, 204 in male and 178 in female) on survival and to validate the utility of cutoff values in BIA recommended from current recommendations ...

Reference Values for Multifrequency Bioimpedance Analysis in Dialysis Patients

Blood Purification, 2004
<i>Background:</i> The role of multifrequency bioimpedance (MF-BIA) in the assessment of fluid status in dialysis patients is still not fully elucidated. Especially, the predictive value of reference values for extracellular water (ECW) has not yet been addressed.

Bioimpedance Analysis of Epithelial Monolayers After Exposure to Nanosecond Pulsed Electric Fields

IEEE Transactions on Biomedical Engineering, 2019
Exposures to pulsed electric fields (PEFs) are known to affect cell membranes and consequently also cell–cell interactions as well as associated characteristics. Bioimpedance analysis offers direct and non-invasive insights into structural and functional
