AACN Advanced Critical Care
AACN Advanced Critical Care (1991) 2 (3): 453–461.
Published: 01 August 1991
Abstract
Nutritional support is an important aspect of care in hospitalized patients, especially those receiving mechanical ventilation. While nutritional assessments can help guide the clinician in determining appropriate caloric intake requirements and refeeding schedules, few tools exist to evaluate the consequences of over- or underfeeding. Metabolic assessment using indirect calorimetry is a new method of nutritional assessment for use at the bedside of the weaning patient. The data obtained from a metabolic assessment can be used to adjust formulas and total caloric intake as well as differentiate between dead space and elevated carbon dioxide production as reasons for persistent hypercarbia

Abstract
As a result of technological progress and a better understanding of respiratory disease processes, new modes of mechanical ventilation for the critically ill patient have been developed. These new methods may offer specific advantages over traditional techniques by avoiding or reducing complications commonly associated with positive pressure ventilation. A thorough understanding of anticipated benefits and potential problems is carefully considered for each mode of mechanical ventilation. Several alternate approaches to ventilatory assistance are discussed. Clinical applications of nursing care are also discussed
