I was taught during my orientation to surgical floor to always put NGT, especially salem sump, to continuous low suction. Some of the other nurses are now telling me that continuous is not right, should be intermitant only. The policy for the floor states continuous which is what I always do. Yesterday a day shift nurse told me I was wrong and the policy was wrong! She said a MD told her to never use continuous and always low intermitant. What do you all think? What is the correct answer? Thanks in advance!
