Bioimpedance – má vůbec význam? - Lukáš Vrána

WebSF-BIA anvender en enkelt frekvens (som regel 50 Hz) og er baseret på en 2-delt kropsanalyse hvor fedtmasse + fedtfri masse = kropsvægt. SF-BIA kan ikke give en pålidelig differentiering mellem ICF og ECF. Og eftersom de fleste SF-BIA-apparater kun anvender en frekvens på 50 kHz, er der risiko for at det elektriske signal ikke kan passere ... WebBackground: The utilisation of bioelectrical impedance analysis (BIA) in heart failure can be affected by many factors and its applicability remains controversial. The present study aimed to verify the adequacy of single-frequency BIA (SF-BIA) and multifrequency BIA (MF-BIA) compared to dual-energy x-ray absorptiometry (DEXA) for evaluating body …
