Enteral feeding devices are indicated when a patient has a functional GI tract but cannot safely or adequately feed by mouth. This includes patients with a swallowing dysfunction or neurologic disorder. Similarly, patients on a ventilator or those with severe reflux require enteral feeding to prevent aspiration. Finally, patients with inadequate nutrition or in a hypermetabolic state (i.e. cardiac disease, renal disease, or pulmonary disease) may not be able to meet their nutritional demands with oral feeding alone and require enteral feeding as supplementation. The indication for enteral nutrition and duration of feeding needed determine the type of tube recommended. Contraindications specific to each feeding device are listed in Table 1.2.
