A patient is to receive an IV drip of the following: Sodium Heparin 7,000 units Sodium Chloride Injection $$ 700 \mathrm{~mL} $$ a. How many milliliters per hour must be administered to achieve a rate of 1000 units of sodium heparin per hour? b. If the IV set delivers 10 drops $/ \mathrm{mL}$, how many drops per minute should be administered?

Key Concepts

Intravenous Infusion Rate Calculation

This involves determining the volume of IV fluid to be administered per unit time to deliver a specific dose of medication. It requires an understanding of the relationship between the concentration of the drug in the solution and the desired rate of drug delivery.

Medication Dilution and Concentration

This concept pertains to the process of mixing a specific amount of medication with a diluent to form a solution with a known concentration. Knowing the total dose and the total volume allows for the calculation of the concentration, which is essential for accurately dosing the medication.

IV Drop Factor

The drop factor is a value that represents the number of drops contained in one milliliter of fluid delivered by an IV set. It is used to convert a calculated volumetric infusion rate (e.g., mL/hour) into a drop rate (e.g., drops/minute), ensuring proper manual administration when using drip-based systems.

Unit Conversion in Infusion Calculations

Unit conversion is a fundamental concept in infusion therapy that involves converting between different units of measurement such as time (hours to minutes) and volume (mL to drops). Accurate conversions ensure that medication is delivered at the correct rate, maintaining efficacy and safety.
