Macrodrip tubing typically has a lower drop factor, ranging from 10 to 20 gtts/mL. This type of tubing is commonly used for less critical infusions, such as blood transfusions. Microdrip tubing has a higher drop factor, usually around 60 gtts/mL. This type of tubing is used for more precise and controlled IV administrations, often in pediatric cases or for medications with a narrow therapeutic range. The higher the drop factor, the slower the infusion rate will be for a given volume and time.
