Predictive Value of Bio-impedance Vector Analysis on Long-term Outcome in ICU Patients

Phase angle, derived from bioimpedance analysis (BIA), reflects tissue quality and quantity in which cell mass, membrane integrity and hydration state are represented. Phase angle, as a measure of body composition, changes with the physical condition of patients and is associated with survival in several disease states and during ICU admission. Aim of the study is to explore the predictive value of the phase angle for long term ICU outcome.
