<H3>Maximum Allowable Blood Loss Calculator <BR>
How much blood can your patient lose?</H3>
<!--msthemeseparator--><p align="center"><img src="_themes/copy-3-of-blank/ablrule.gif" width="600" height="10"></p>
</CENTER>
Enter patient's weight in kilograms and Hb in g/dl (i.e. about 14).
If you wish, you may change the minimum Hb limit and the volume of blood per kg body mass.
Press the "Let's See!" button to calculate the MABL!
