Bioimpedance spectroscopy in haemodynamic analysis

Journal of Physics: Conference Series, 2010
Venous insufficiency is estimated to affect between 10% and 35% of the population in the US with symptoms ranging from mild discomfort to chronic ulceration which may reduce quality of life. Early diagnosis is the key to pre-emptive treatment. We have previously reported [5] an impedance technique for measurement of calf muscle pump function although ...

Bioimpedance analysis and intradialytic hypotension in intermittent hemodialysis

Clinical Nephrology, 2006
Intradialytic hypotension (IDH) is one of the most severe complications during hemodialysis. Its appearance is caused in part by rapid fluid removal with concomitant failure in blood pressure regulation but also by other dialytic-dependent and independent factors.We investigated total (TBW), extracellular (ECW) and intracellular water (ICW) in chronic ...
