eHealth Apps

© LNNI Healthcare Professional Calculator App

This App was created in partnership with the Ulster University in recognition of the lack of consistency in calculator models and availability of remote access. 

It is designed for healthcare professionals to:

  • ensure regional practice is supported by a consistent limb volume and Body Mass Index (BMI) calculation format
  • have available access to calculations by PC, phone or tablet
  • reduce the cost of purchasing and up-keep of current limb volume calculators/software

A set of guidelines has been developed to support initial use. Download the guidelines here. Please note that HSCNI/NHS users may not be able to download this file at work due to security restrictions, so please do so from a home computer. Instructions on adding the APK file to your Anroid mobile/tablet device can be found here.

© LNNI Calculator Excel Spreadsheet

As a pre-cursor to app development the equation used to calculate limb volume and BMI was embedded into an excel spreadsheet. Clinicians can record limb circumference measurements and calculate limb volumes and BMI utilising this spreadsheet. Again this:

  • supports consistent limb volume and Body Mass Index (BMI) calculation format
  • provides access to calculations by PC
  • reduces the cost of purchasing and up-keep of current limb volume calculators/software
