The arrow of bioimpedance.
The value of bioimpedance in hemodialysis remains under debate. However, when appropriately used, bioimpedance can provide measures of body hydration characterized by a small error, a high sensitivity to changes in water volume, and, above all, a linear relationship over a wide range of volume changes. These features make it very useful to measure body hydration in hemodialysis patients.
