I fed my mom through feeding tube.even after feeding n closing the end of tube,i could see liquid in the tube.what does it mean?pls hlp

Obstruction?: Perhaps there is an obstruction to the tube. Have visiting nurse do an assess & flush & follow her recommendations. If flush doesn't work & the problem persists, then report it to Mom's treating physician. Also, if any signs of distress, like new breathing difficulties, tightness or tenderness in the abdomen, then report that immediately too, as it may signal need for urgent measures.
