PH2O, PB and R field values have been prepopulated for convenience, they can be overwritten as needed.

* FIO2 can be entered as a % or fraction. L/min conversion can be done as follows:
FIO2 L/min = (FIO2 % - 21)/3 (only if FIO2 is > 21%). So for values below 21% the normal values for L/min don't apply.
