This program simplifies process of calculating Total Blood Volume (TBV) and Total Plasms Volume (TPV)- data, which are needed in blood surgery procedures. You have only drag three sliders on the screen - and that's all. No more long tables and calculations with a stupid calculator! You Palm take all the care. Program is developed in three versions - Russian metric, English International (metric) and English native (Empire units). You can also visually control the level of HCT - program knoows about "normal" range for all categories of patients. Also in new version BloodCalc 1.3 ypu can freely switch to other application - program remember your last data. And on request of my customers, I include indicator of BMI (body mass index).
