Fetal IV Transfusion Calculator
By JL Software
Open iTunes to buy and download apps.
The Fetal IV Transfusion Calculator on your iPhone or iPod touch lets you compute the volume of red cells to be transfused right at the bedside after determination of initial fetal hematocrit.
Using your choice of two formulas, the Fetal IV Transfusion Calculator eliminates the need to pre-calculate transfusion volumes for various fetal weights and opening hematocrits - all data can be rapidly selected at the bedside during the IUT procedure.
No typing is required. Select the formula desired (Socol or Giannina) and a donor hematocrit of 75%, 80%, or 85% with single finger taps.
Then dial the estimated fetal weight on the first wheel, the initial hematocrit on the second wheel, and the target hematocrit on the third wheel.
The volume of red cells required is read immediately from the fourth wheel, and responds in real time to changes in any of the other settings.
A calculation of 20% of the estimated fetoplacental blood volume is constantly displayed at the bottom of the screen as EFW is changed.
Now you can have the calculation that you need right in the procedure room without calculators, computers or preparing tables ahead of time.
All future updates will be free of charge.
Socol: V2 = ((HCT3 - HCT1) * (150 * EFW/1000))/HCT2

Giannina: Volume = 0.02 * EFW for each 10% rise in hematocrit.

What's New in Version 1.1
Fixed slight memory leak.
good but can be better with little trouble by the developers
I love the app but it could be better with different donor hcts added. Our hospital has trouble getting blood packed to a hct of 75% (lowest option in this program) and hence more options here would be helpful with minimal effort by the programmers.
