The assessment of metabolic parameters related to energy expenditure has a proven value for weight management; however these measurements remain too difficult and costly for monitoring individuals at home. The objective of this study is to evaluate the accuracy of a new pocket-sized metabolic analyzer device for assessing energy expenditure at rest (REE) and during sedentary activities (EE). The new device performs indirect calorimetry by measuring an individual's oxygen consumption (VO2) and carbon dioxide production (VCO2) rates, which allows the determination of resting- and sedentary activity-related energy expenditure. ⋯ The findings demonstrate that the new pocket-sized metabolic analyzer device is accurate for determining VO2, VCO2, and energy expenditure.

Nutritional assessment of critically ill patients has created controversy. However, it is well established that malnourished patients who are severely ill have worse outcomes than well-nourished patients. Therefore, assessing patients' nutritional status may be useful in predicting which patients may experience increased morbidity and mortality. ⋯ SGA, an inexpensive and quick nutritional assessment method conducted at the bedside, is a reliable tool for predicting outcomes in critically ill patients.
