From: The consequences of sudden fluid shifts on body composition in critically ill patients
Relationships between intradialytic percentage variation of tissue resistance measured by bioelectrical impedance at 5Â kHz (R 1 ) and percentage variation of extracellular water (ECW) (A) , and between percentage variation of tissue resistance measured by bioelectrical impedance at 1Â MHz (R 2 ) and percentage variation of intracellular water (ICW) (B) in 31 critically ill patients. R1 and R2 were normalized by height2 (H2). H2/R1 is a linear function of ECW and H2/R2 is correlated with fat-free mass and body cell mass in healthy adults.
