26Using the Drug Calculator
Drug mixtures for intravenous (IV) drug infusions combine information on drug dose, rate, amount,
volume, concentration, and standardized rate. The Drug Calculator helps you to manage infusions by
calculating one of these values at a time.
*Be aware that your hospital may use either ‘µg’ or ‘mcg’ as an abbreviation for microgram. These
abbreviations are equivalent.
WARNING Before you administer any drug, always check that the correct calculation units and patient category are
selected. Consult your pharmacy if you have questions.
Decisions on the choice and dosage of drugs administered to patients must always be made by the
physician in charge. The Drug Calculator performs calculations based on the values input during use,
it does not check the plausibility of the calculations performed.
