I would love it if the BMI calculator included other algorithms like the one I mention at:
Body Mass Index – Lean Body Mass | CoachBioArt

More options are better

great app though. Would you be interested in a module for more chemistry-like calculations?

[palmdoc2005]

Thanks for your suggestion
I am thinking of putting it all into one module - BSA, BMI, IBW and Lean BW
Anyone have thoughts or would you prefer them separate?

How about including an fe urea option to augment the feNa? I find myself using that almost as often.

Ok done.


8/7/9 v1.1.0
Added Fractional Excretion Urea
Added Unit toggles for FrENa and Creatinine Clearance

Updated thread title to no longer show version number here.

Download the latest version from the Homebrew Apps Gallery: PreMedi

Application updated with Lean body weight
I have consolidated BSA, BMI, IBW and LBW into one single module

I believe there are several variants for the calculation of Lean Body Mass.
The current one used is the Equation of Boer

[CODE]lean body mass for adult males in kilograms =
= (0.407 * (body weight in kilograms)) + (26.7 * (height in meters)) - 19.2
lean body mass for adult females in kilograms =
= (0.252 * (body weight in kilograms)) + (47.3 * (height in meters)) - 48.3
[/CODE]

There's also the James' formula

[CODE]Lean Body Weight (men) = (1.10 x Weight(kg)) - 128 x ( Weight2/(100 x Height(m))2)
Lean Body Weight (women) = (1.07 x Weight(kg)) - 148 x ( Weight2/(100 x Height(m))2)[/CODE]

The LBW obtained by the two methods are very similar so I went with one - the Boer formula

If anyone has suggestions for calculation modules, it would help greatly if you link to references which show the formula or algorithm, otherwise it will take much longer, if ever, for your suggestion to be included.

A quick update:

Calc button is now green
Added two more global variables: age, creatinine - I think this helps speeds up entry since one might be using the same variable for various scores eg serum creatinine in CClr and MELD

[palmdoc2005]

Update v 1.3.0
- added Anion gap
- added error trapping (no more NaN errors hopefully!)

[palmdoc2005]

Added a demo video:
YouTube - PreMedi Demo

Sorry if this has already been requested but you you be able to include the version number in the About section?

Good suggestion will implement it. Wonder if there is an automatic way to get the info from appinfo.json?

palmdoc kudos to you!

I have a couple of requests:
- pregnancy calculator
- corrected sodium

[palmdoc2005]

I did try to add in a Pregnancy calculator but fumbled badly with the Date picker widget. Will need some help on this so give me a bit of time.
Will add the corrected sodium and others later as well.

I presume you mean corrected sodium for hyperglycemia?

Which correction factor does one use?
http://www.globalrph.com/hyperglycemia.htm
corrected sodium = sodium + 0.016 x (Serum glucose - 100)

or this one?

Adjusting Sodium Levels in Patients with Hyperglycemia - October 15, 1999 - American Academy of Family Physicians

[palmdoc2005]

Alright, in the end I decided to include both methods (standard and Hillier's)
PreMedi now updated to v 1.4.0b with Corrected Na for hyperglycemia

I have also made minor changes:
Added Disclaimer
Version number is automatically displayed in the About box

[sensai28]

I have a request for a GFR Calculator. I am currently using GFR Calculator on my computer.
Thanks for the great app!
