Bioimpedance Spectroscopy for the Differential Diagnosis of Hyponatremia

Bioimpedance Spectroscopy for the Differential Diagnosis of Hyponatremia

We aimed to investigate the role of bioimpedance spectroscopy for the diagnosis of hyponatremia

• Up to now, "Hyponatremia" differentially diagnosed by physical examination, plasma and urine osmolalities, Echocardiography and biochemical measurements.
• The purpose of this study is to determine whether bioimpedance spectroscopy can be used for the detection of hypovolemia and hypervolemia for the differential diagnosis of hyponatremia.

Inclusion Criteria:

• Willing to participate in the study with written informed consent
• Older than 18-years

Exclusion Criteria:

• The presence of pacemaker or defibrillator
• Artificial joints, pin or amputation
• Pregnancy or lactating.
