Decreasing aspiration risk with enteral feeding.

Aspiration is a clinical concern in patients receiving enteral tube feeding. Aspiration can result in pneumonia leading to increases in the use of antibiotics, length of hospital stay, and the risk of mortality. Pneumonia caused by aspiration of gastric contents is of particular concern in patients who require mechanical ventilation and feeding by nasogastric tube. This article summarizes factors that might influence the development of aspiration pneumonia and minimize risk, such as the position of the patient's body, method of feeding, and size of the feeding tube.
