We had a conversation with Michael Garthwaite and all these functions are going to use the functions in the conversions.py since this method of doing it is very error-prone. We should plan soon to make these changes.
We got recommendation to monitor arterial pressure even when not dialyzing if patient is still connected (so all other treatment mode states other than dialysis when not delivering saline bolus), but didn't want to apply the user provided limits - just want to monitor for max pressure situation.
