While effort has been made to ensure that calculations are accurate and that conversion factors are in accordance with current accepted medical practices, use of this application is entirely at your own risk. This application should only be used by trained medical professionals and all results should be double checked by hand. Use of the app requires acceptance of the terms of use that are included with the application. Please send support requests and feedback using the link in the About tab of the app, though as a free academic tool we only have limited resources to address new feature requests.
