MACage Calculator is a reference tool that allows anesthesia students and providers to easily calculate minumum alveolar concentrations (MAC) for different volatile agents.

The formula used in this app is based upon Mapleson's research (Mapleson WW. Effect of age on MAC in humans. Br J Anaesth 1996; 76: 179-85).

N2O + volatile agent = ? MAC

This app does not calculate MAC for a volatile agent combined with differing percentages of N2O. Cheaper to google a MAC graph.

Very helpful

I have been using this app for a week now and it has been very helpful in the OR. I think it is especially important for pediatric anesthesia.

Great but...

Would be nice if you also added MAC in 60-70% N2O
