Determining dry weight using multi-frequency bioimpedance
Accurately determining the dry weight1 of hemodialysis patients is a major challenge in the clinical treatment of the patient. A study was conducted with 40 patients to understand the benefit of Bioelectrical Impedance Analysis, or Bioimpedance2, which has been recognized as a noninvasive, simple technique to determine the dry weight in these patients.
During the study, each of the 40 patients underwent approximately eight dialysis sessions. All of the session data were collected and checked for quality issues, such as incorrect use of the bioimpedance device, the device not being turned off between sessions, etc.
