WETFLAG Checker - Instructions

What is it?

I have written a basic tool that calculates emergency paediatric drug doses using weight calculations based on age and the WETFLAG mnemonic.  It is available as an app for Android.

Quick Links

Some important points about the app
  • I see this tool as a calculation checker; use at at your own risk - please ensure you also do your own calculations and refer to the latest resuscitation guidelines
  • This app is devleoped by myself; I have no connection to the ALSG and I make no claims that it is up to date to their latest guidelines
  • This script uses the 2010 ALSG APLS Formulas to calculate weight from age namely
    • 0-12 months: (0.5 x age) + 4  
    • 1 - 5 years: (2 x age) + 8  
    • 6 - 12 years: (3 x age ) + 7
  • The WETFLAG values are derived from 2010 APLS values
    • For ages above 12 years or for weights above 44kg the values for the WETFAG formula are based on the reuscitation council's paediatric emergency sheet
    • For ages in months above 12 months, this script always rounds down to the nearest year and then calculates weight; therefore a child of 23 months is assumed to be 1 year of age
    •  If weight is used as an input, ET size and length is not calculated
    • ET size is calculated raw to decimal place and not to the nearest 0.5
    About the android apps

    • Version 3 for newer Android phones - Link to app here.  Works well on the latest version of the Android operating system (Jellybean); I would be grateful for your testing on other versions.  Note that some android phones do not have a "done" button on the onscreen keyboard - in this case press the back button (usually the bottom left one) to get rid of the keyboard.
    • Older Android Phones: - Unfortunately this app does not work on Android 2.3.6.
