It is an iOS implementation of the nomograms published in "Age-related iso-MAC charts for Isoflurane, sevoflurane and desflurane in man" by Nickalls and Mapleson, in BJA 91(2) 170-4 (2003).
Given the patient’s age, end-tidal nitrous oxide concentration and chosen volatile agent, it allows calculation of the required end-tidal concentration of volatile agent to achieve a particular MAC adjusted for patient age. It also allows the reverse, that is calculation of the age adjusted MAC given the ET volatile concentration.
After entering
+ Patient age
+ Volatile agent used (sevoflurane, isoflurane or desflurane)
+ End-tidal nitrous oxide (%)
And either:
+ Desired MAC OR
+ End-tidal volatile concentration (%)
The other of these two that you do not enter will be calculated automatically.

Awesome app
supa sweeet
Love it! Use it everyday. Calculations are based of the original isomac curves. App even allows you to download the article by Nickalls and Mapleson from the BJA. Easy to use.
I use it daily at work.

I'm a CRNA and I work with an older population. This app helps me achieve my target Mac value without tanking the BP and HR. Very useful and affordable.
