So I was skeptic that it works based on the reviews. The bad reviews boil down to operator error and not understanding the formulas. So I downloaded and tested the app to check validity.
The formulas I used were:
Pulse pressure (PP) = SBP - DBP
MAP = DBP - 1/3PP
If you do the math on various blood pressures the math checks out and works as expected. The app does the same rounding a person would by hand of .5 goes up and .4 and below stays the same. Don’t believe the bad reviews from a lack of understanding the actual math equations to get these numbers. If you don’t believe me try for yourself. I mean the app is free. See for yourself.
(Disclosure: I am not financially or benefiting in any form from my positive review. Just an ems guy who was looking for a calculator to do the math for me. Saw some bad reviews, and tested it myself to see if it was a trash app or not. )
Hoping this review helps the next guy looking for a MAP calculator.
