Critically ill patients placed on enteral nutrition (EN) are usually underfed as most of them are placed on "Frequency-based Enteral nutrition" (FBF). Interruptions are frequent due to various reasons.
A "volume-based feeding" (VBF) allows to adjust the infusion rate to make up for interruptions in delivery. Studies have shown that VBF strategy is safe and improves delivery to better meet caloric requirements than the standard more commonly used frequency-based strategy.
