BSA is a measurement used in many medical tasks. Various
Body Surface Area
formulas have been developed over the years, originally by
Dr.s Du Bois & Du Bois, followed by Gehan and George, Haycock, Boyd and
Mosteller. These formulas all give slightly different results. It is
probably not worth the trouble to debate about which formula may or may not be
slightly better. A bigger issue is lack of standardization. The Mosteller
formula is gaining support as a common standard because it is much simpler and
can be memorized and easily calculated with a hand-held calculator.
Some of you will prefer the old BSA calculator, which fit better onto a standard computer monitor. But it looked quite
old and I was forced to change the layout, into a single column and make it responsive for use on cellphones.
I've used this redesign opportunity to show off my soft pastel colors style (which I made myself), and introduce the Moose.
Back in 1999, there was confusion about BSA and people were always looking up- and debating- the formulas.
Nowadays the internet brings calculators like this to us instantly, and we just get our work done a little faster.
This calculator DOES HAVE some WEIRD behavior, if you enter weight or height values that are very large or small.
It either shows error messages or changes the values. Way back in 1999 I thought that was a good safety check,
but I'm having second thoughts now. I may remove or alter that to be less annoying.
Hi there! I'm Dr. Halls, and I am excited to introduce you to the Talking Moose.
The Moose is software, a 3D talking character on your computer.
It's kindof famous for telling jokes, but does a lot more than that.
You can find video of the moose on my Google+ page or
Youtube channel or
info about me on my LinkedIn page.
