Hi everyone!
We'll be learning about an iron and anemia related topic today.
When a patient has severe anemia, you need to calculate the TDI (Total dose infusion) for parenteral therapy.
And there are various formulas with all sorts of numbers in em.
I'm allergic to memorization but I love memory aids! ;)
Let's start with the formulas!
Haldane formula for TDI = 0.3 x weight (lbs) x (100 - Hb %) + 50%
Haldane's formula mnemonic:
H has 3 strokes | - |, so 0.3 is the multiplication factor.
Haldane has a L, for weight in Lbs.
Haldane has a H, H for Hundred. So hundred minus Hb %.
Add half of hundred, 50%, for stores.
