Long term tubes (no nose)
-tube put directly into stomach wall
Percutaneous endoscopic gastrostomy (PEG)
-machine acts as feeding pump
-controls rate of formula delivery
pump-assisted

continuous feeding
delivers constant rate of formula over a specific period of hrs followed by pause
cyclic feeding
-no machine, uses syringe to deliver large volume formula
bolus feeding
-formula container opened to transfer formula
-prone to contamination
-8 hr hang time
Open system
sterile container pre-filled with formula directly administered
-controls contamination
-24/48 hr hang time
Closed system
