Basal energy expenditure accounts for a large component of energy losses, and a clinical estimate of this form of thermogenesis is usually derived from a prediction equation. The most widely used prediction equation was developed in 1919 by Harris and Benedict. The energy requirements of healthy and diseased individuals are often estimated from application(More)
Respiratory, cardiovascular, and metabolic changes were monitored during balance studies in undernourished patients receiving continuous enteral formula feeding. The nutrient solutions, either high carbohydrate (83% of kcal) or high fat (50% of kcal), were administered at doses ranging from 2.7 to 6.0 X 10(-2) kcal X kg fat free body mass-1 X min-1. For(More)
OBJECTIVE Occupational injury and illness rates for volunteer responders have not been well documented. We analyzed data specific to volunteers from the American Red Cross (ARC). METHODS Data collected by the ARC between 2008 and 2012 were analyzed to identify disaster factors associated with responder injuries and illnesses. We focused on disaster-relief(More)
An indirect calorimetry system was assembled from three readily available major components: a digital pneumotachograph, an oxygen analyzer, and a carbon dioxide analyzer. A one-way valve, face mask, and meteorological balloon completed the system. Accuracy was assessed by comparison to direct calorimetry in hospitalized patients undergoing enteral(More)
Continuous enteral feeding produces changes in metabolism and cardiopulmonary function. Recognition of these effects and the potential complications of tube feeding is essential prior to initiation of therapy. This article reviews the enteral feeding technique and associated metabolic and technical complications in detail.
