The Use of Bio-Electrical Impedance Analysis Derived Parameters for Evaluating Fluid Accumulation in Critically Ill Patients Admitted to ICU: a Cohort Study

This research will begin by identifying subjects through the collection of initial data. The identification of subjects will involve using BIA (Bioelectrical Impedance Analysis) equipment. Subsequently, the subjects will be divided into two groups based on the initial BIA test results of body fluid balance. The first group will comprise patients with a body fluid balance exceeding 500cc, while the second group will consist of patients with a body fluid balance of 500cc or less. Throughout the study, various BIA-derived parameters will be closely monitored for both groups, starting from the initial BIA test until the patients are discharged from the ICU or for a maximum of 7 days of ICU care from the time of the first test.
