EMS Calculator is a one page ultra-fast emergency pediatric and adult drug dosing calculator. There is only one control - the patients weight. This immediately gives you a dosing range, eliminating the need to flip through pages of information.
If you want to read about the drug you can get a textbook; otherwise, this gives you everything you want - fast! The weight range is from 1 to 250 kg. The information button gives you the range calculation. A nicardipine infusion range is also given for the treatment of severe hypertension.
