Many of us use TCI on a daily basis. Indeed some people use it almost exclusively. Fewer appreciate the remarkably small data set that the algorithms were created from. Even fewer understand the limitations of the algorithms. If you want to find the answers to the statements below can I suggest you look at the chapter “Everything you should know about Propofol TCI” in the book The First Year. It can be freely downloaded from the College Library: click on Library Guides> Medical Education> Featured Resources and scroll to the bottom. The pdf is waiting for you. The cover is reproduced above. The TCI pump algorithms are poorly treated in the texts.
