Hur et al. report that fluid management guided by bioimpedance spectroscopy devices might improve cardiovascular parameters in patients on haemodialysis. However, caution is advisable when using these devices for extracellular volume assessment as overzealous reduction of target weights based on extracellular to intracellular volume ratios could cause premature loss of residual renal function.
