Evaluation of Nutritional Status in ICU : Interest for the Measurement of Body Composition by Body Bioelectrical Impedance and Comparison With Several Methods

Study Overview
=================
Brief Summary
-----------------
Prospective cohort, monocentric non-randomized and interventional clinical study in ICU assessing the evolution of body composition using bioelectrical impedance analysis.

Detailed Description
-----------------
Prospective, monocentric non-randomized and interventional clinical study in ICU assessing the evolution of body composition using bioelectrical impedance analysis (phase angle, fat mass, muscle mass, fat-free mass, body water); comparison with four methods for assessing nutritional status. ; compare length of mechanical ventilation, length in ICU and energy expenditure rest between malnourished and non-malnourished patient.
