FAQs

Multiply the patient's weight in kg by the prescribed dose in mg/kg. For example, for a 70 kg patient with a dose of 5 mg/kg: 70 × 5 = 350 mg.

Micrograms per minute, a common unit for infusion rates in critical care settings. It's often used for potent medications like vasopressors.

Divide the total volume by the total time in hours. For example, 1000 mL over 8 hours = 1000 ÷ 8 = 125 mL/hr.

1 mg (milligram) = 1000 mcg (micrograms). Always double-check units to avoid medication errors.
