It is the same as a non vented pt.. You will listen to lungs, abd, note all dressings, ivs, foley, do they have a NG or OG tube? On a vented pt however you would add the ETT size, location, vent settings. Is the pt sedated? What are they on and how much. Neuro checks are a little different. How is the pt, calm, agitated, over sedated, attempting to remove tubes and lines..Does he follow commands off sedation, MAE, are the pupils = and reactive, what size are they... You would chart all of that..
As with any head to toe, start at the top and work your way down, chart it the same way. Note what you see on the pt that they were not born with lol, like foley, SCD's etc..
The more you do it, the better you will becoming at charting it all.
