Question 1

What is an IV set used for?

Accepted Answer

An IV set is used to deliver fluids, medicines, electrolytes and nutrients from an IV bag or bottle directly into a patient's vein through a cannula. It is used for rehydration, intravenous medication, surgery, emergency care and paediatric infusions.

Question 2

What is the difference between a micro IV set and a macro IV set?

Accepted Answer

The main difference is the drop factor. A macro IV set typically delivers 10, 15 or 20 drops per mL and is commonly used for routine adult infusions and larger fluid volumes. A micro IV set delivers 60 drops per mL and is used when smaller volumes or more precise flow rates are required, such as in paediatric and neonatal care. The appropriate set depends on the prescribed infusion rate and the patient's clinical needs.

Question 3

How many drops are there in 1 mL of an IV set?

Accepted Answer

The number of drops per mL depends on the IV set's drop factor, which is specified on the product packaging. Macro IV sets commonly deliver 10, 15 or 20 drops per mL, while micro IV sets typically deliver 60 drops per mL. Always verify the drop factor before calculating or setting an infusion rate.

Question 4

What is the difference between vented and non-vented IV sets?

Accepted Answer

A vented IV set has a filtered air inlet that allows air to enter rigid containers, such as glass or certain plastic bottles, so the fluid can flow properly. A non-vented IV set does not have an air inlet and is generally used with collapsible IV bags that contract as the fluid is dispensed. Select the type according to the infusion container and the manufacturer's instructions.

Question 5

What is the difference between an IV set and a blood transfusion (BT) set?

Accepted Answer

An IV set is designed to administer intravenous fluids and compatible medications, whereas a blood transfusion (BT) set is specifically designed to administer blood and blood components. A BT set typically includes a dedicated blood filter, commonly with a 170–200 micron rating, to retain clots and aggregates. A standard IV set should not be substituted for a blood transfusion set.

Question 6

Is an IV drip set the same as an IV set?

Accepted Answer

Yes. The terms IV set, IV drip set, drip set, infusion set and IV administration set are commonly used to describe tubing used for gravity-based intravenous fluid administration. However, IV sets differ in design and function, including macro drip, micro drip, vented and non-vented configurations. Choose the appropriate type based on the prescribed therapy, infusion container and clinical requirements.

Question 7

What is the price of an IV set?

Accepted Answer

IV set prices vary depending on the type, brand, components, specifications and pack size. Standard macro drip sets may have a lower cost per unit, while micro drip sets, burette sets and sets with precision flow regulators may cost more. Hospitals, clinics and other healthcare facilities should compare the per-unit cost, product specifications, sterility, packaging and supplier terms when purchasing IV sets.

Question 8

Can an IV set be reused, and how often should it be changed?

Accepted Answer

IV sets are generally sterile, single-use medical devices and must not be reused. Dispose of them according to applicable biomedical waste management requirements and the healthcare facility's infection control policy. The replacement interval for continuously used infusion sets depends on the type of infusion, the products administered and current clinical guidelines. Sets used for blood, blood products or lipid emulsions may require replacement within 24 hours, while other continuous infusion sets may have different replacement intervals. Always follow the manufacturer's instructions and the facility's current infection prevention protocol.
