Great application, but would like to see option for capillary sample

I work in a level III NICU, and most of our blood gases (after the UAC is removed) are done by capillary sample. All of the blood gas calculators Ive seen assume the sample is arterial. Could you develop an option where the PaO2 is not used as a determining factor? Otherwise, Im VERY glad to see this app!!!
