â€‹Can mathematics save someone’s life?

Yes, it can. Literally.

Body fluids drains out very rapidly after extensive burns. The lost fluid must be re-introduced in the form of Intra venous Infusion. Now the rate at which fluid to be given has to be calculated. Most commonly used formula(parkland formula).

The **Parkland formula** is mathematically expressed as:

**V=4.m.(A.100)**

where m=mass is in kilograms (kg), A=area as a percentage of total body surface area, and V=volume in milliliters (mL). For example, a person weighing 50 kg with burns to 20% of his or her body surface area would require 4 x 50 x 20 = 4,000 mL of fluid replacement within 24 hours. The first half of this amount is delivered within 8 hours from the burn incident, and the remaining fluid is delivered in the next 16 hours.
