Potassium Deficit
e.g.: Potassiumdeficit (mmol) = weight (kg) x 0,2 x 2 x (desired serumlevel of potassium (e. g. 4,5) – measured actual serumlevel of potassium [mmol/l]
After calculating the deficit a tool to calculate correction by infusiondrip via mixture of KCl 14,9% in other fluids would be very helpful

minute volume correction according to PaCO2
There is a interesting formula for minute volume correction according to PaCO2:
Desired MV = (actual MV x actual PaCO2)/calculated PaCO2
MV can be splited - MV = Tidal volume x respiratory rate; this helps to simplify calculations when you have only RR.
calculated PaCO2 is derived from the Winters formula.
It works for controled ventilation and some types of SIMV.
