Evaluating calf bioimpedance measurements for fluid overload management in a controlled environment
Objective : To evaluate the relationship between calf bioimpedance measurements and fluid removal in
a controlled environment (hemodialysis) as a first step toward using these measurements for remote
congestive heart failure (CHF) monitoring. Approach : Calf bioimpedance measurements were recorded
in 17 patients undergoing hemodialysis (9/17 (53%) CHF, 5/17 (30%) female). Measurements were
performed before and after hemodialysis. Additional parameters related to hemodialysis and patient
fluid status such as estimated dry weight were also recorded. Main results : Calf bioimpedance
changes depended on calf fluid status as assessed by calf normalized resistivity (CNR). Patients
with lower calf fluid overload (as assessed by CNR greater than ##IMG##
