Gastrostomy or Gastro-jejunum Tube: Pump Feeding

  • For bolus feeding, your child’s health care provider or home health nurse will tell you how much liquid food to use for each feeding. You’ll also be told how often to feed your child every day. Write these numbers below:

How much to give at each feeding:  _________________________

How often to feed: ­­ __________________________

  • For continuous feeding, the amount of food to be given and time frame are often set on the pump for you. Don’t change these settings unless you’re instructed to do so.

  • Wash your hands with soap and water.

  • Make sure the pump is in the STOP/OFF mode.

  • Check the label and expiration date of the liquid food. Don’t use any can (or bag) if the expiration date has passed. Instead, get a new can (or bag).

  • Make sure that the clamp on the feeding bag tubing is closed.

  • Pour a little more than the prescribed amount of liquid food into the feeding bag.

  • Hang the feeding bag on the pole above the pump. Make sure the feeding bag tubing hangs straight.

  • Open the clamp slowly. Let a small amount of food run through the end of the feeding bag tubing. This clears air out of the feeding bag tubing. It also helps keep your child from having gas later.Feeding bag hanging from pole on pump. Feeding bag tubing goes from bag to pump. Clamp is in middle of tubing. Finger is pressing the On button.

  • Connect the feeding bag tubing to the other end of the extension tubing.

  • Open the clamps on both the feeding bag tubing and extension tubing.

  • Check that the settings on the pump are correct.

  • Turn the pump to START/ON.

  • After the feeding, disconnect the feeding bag tubing from the extension tubing. Then, flush the extension tubing with water (as you were shown in the hospital).

  • Disconnect the syringe from the extension tubing.

  • Disconnect the extension tubing from the G- or G-J tube.
