Your English is just fine.
I work with consumers online only and do not have a patient practice. I have not worked in a nutrition support service (TPN, TF or enteral formulations) since the early 1980’s. If you would like to subscribe to some listserv for nutrition support I will send you information on how to join these online discussion groups (listserv) and you can ask the group by posting a message to the listserv. If you have problems subscribing (joining) a listserv, write to the owner of the listserv for help.
It depends on the diagnosis of intensive care patients. For instance, if they are on a respirator, PulmoCare is good because it is lower in carbohydrate and therefore less demanding on oxygen needs. There are many enteral (oral) liquid meal replacement products out there and I would recommend talking to someone in the group above to find the best for a patient’s diagnosis.
