Patient selection: enteral feeding
Criteria for feeding intolerance:
(1) large gastric residual volume (GRV)
(2) gastrointestinal symptoms temporally associated with enteral feedings
(3) inadequate delivery of enteral nutrition
A large gastric residual volume may range from 150 to 500 mL, up 1,000 ml. In the implementation >= 250 mL will be used.
Gastrointestinal symptoms may include:
(1) diarrhea
(2) vomiting
(3) abdominal distension
Inadequate delivery of enteral nutrition may be based on:
(1) less than 70-90% of intended calories (energy requirements)
(2) less than 500-750 kcal per day.
Less than 750 kcal or less than 80% of target may be used in the implementation.
