My husband has a gravity bag. My understanding of a feed tube is. The person should be sitting in an upright position 30% degree angle, 45% is better when receiving feed by feed tube. Never lie flat when receiving feed because it may come up. SLOW DRIPS are important. We find when a person has a feed tube we have their head at an angle to prevent any type of spitting up while they are sleeping. This practise is used while the person is NOT taking feed. I have a resident who as far as I can remember has NEVER had a change in their feed tube. The feed tube requires an opertion and can be dangerous to boot especially with a person who has tumours in their throat (bleeding can occur) eg. my husband is a good example. I am not a doctor and this is my point of view. Hope it helps. Check with your doctor. Carol Ann.
