Hi! The Maine EMS app is updated for the 2021 protocols. You may need to visit the app store or google play (depending upon your device) and manually update the app ("Maine EMS Protocol App version 2021.12"). We are also working with the app developer on a couple of menu errors within the app, so please refresh your app if you are reading this. We know there is a problem with dosing on the app calculator and are working on resolving this and will share when this is corrected.
