Term: MediMath

MediMath is an application for the iTouch or iPhone. MadiMath
is a calculator for physicians that has 74 different features. It has a
great interface that operates smoothly. Being an application on the
iPhone and iTouch helps its portability and can be accessed whenever
needed. This is very helpful to physicians, for they will spend less time
crunching numbers, and more time with the patients, which is more
time efficient and saves money overall. This application makes it very
easy; all you have to do is enter the numbers, factors, units and get a
result without digging through multiple screens.

Some of the types of calculators on the MediMath application include:
  • APGAR Score
  • Bicarbonate Deficit
  • Body Mass Index
  • Body Mass Index for Pediatricians
  • Hepatitis Discriminant
  • LDL Cholesterol
  • MELD Score
  • Oxygenation Index
  • PELD Score
  • Sodium Deficit
  • Water Deficit
  • GRF (overall index of kidney function)
  • Predict cardiac mortality with the Framingham cardiac risk score
  • Calculate the reticulocyte index

This application is helpful for any kind of medical profession; nurse,
physician or trainee. It even has a "Favorites" section for the
calculations you make the most, so that it is even easier to have
the calculators you use the most at your fingertips for easy conversion.

Some physicians that have downloaded the application have
given there feedback on it. The designer of the program has taken
their feedback and made adjustments and added features to the
application since it was released.
