IV Set for Intravenous Infusion Therapy
An IV set (also called an infusion set, IV administration set or giving set) is a sterile tubing system used to deliver fluids, medications or blood products directly into a patient’s bloodstream. In practice, a fluid bag or bottle containing the prescribed solution is hung above the patient, and the IV set connects the bag to the patient’s venous access device. For example, an NHS clinical glossary defines a “giving set” simply as the tubing that transports IV fluids from the bag (or bottle) to the patient, with flow controlled by either an electronic infusion pump or a manual roller clamp. In short, an IV set is the assembly of spike, chamber, tubes and connectors that enables controlled intravenous infusion.
Key Components: A standard IV set typically includes the following parts:
- Spike (piercing tip): A rigid, pointed spike (often molded of plastic) that is inserted into and punctures the port of the IV fluid bag or bottle. This allows fluid to enter the set.
- Drip chamber: A transparent chamber attached below the spike. It lets caregivers see individual drops of fluid flowing, which confirms flow is occurring. It also traps any air bubbles so only liquid continues down the line when the tubing is primed.
- Tubing with flow regulator: Flexible tubing (usually PVC or silicone) carries fluid from the chamber toward the patient. A roller clamp or dial regulator on the tubing allows manual adjustment of flow rate. (Modern sets may include brake clamps or anti-siphon valves for safety.)
- Injection port(s): One or more needle-free injection ports (Y-sites) along the tubing allow secondary medications or bolus doses to be injected without disconnecting the primary line.
- Connector (Luer lock or slip): The distal end of the tubing has a fitting (typically a Luer-lock connector) that securely attaches to the IV catheter or cannula in the patient’s vein. Some sets have a Luer-slip tip for syringe attachment instead.
Use and Flow Control: When in use, the IV fluid bag is hung high (e.g., on an IV pole) so gravity helps push fluid through the tubing. Flow is adjusted by the roller clamp or regulated by an infusion pump. A pump can deliver very precise rates, whereas gravity flow uses the clamp to roughly meter drops per minute. Before connecting to the patient, the line is primed by flushing fluid through the tubing to remove air (preventing air embolism). Each IV set is sterile and generally single-use (disposed of after one patient) to avoid infection. In clinical practice, IV sets can deliver a continuous drip of fluid or can be used intermittently with injections, depending on the therapy.
An IV set is the complete tubing and accessory assembly that safely delivers IV fluids into a patient’s vein. Its design – including the spike, drip chamber, clamps and connectors – ensures that healthcare providers can control the infusion rate and add medications as needed

- Vented IV sets: Configured with an air-inlet filter for use with rigid glass IV bottles — required to maintain continuous flow in non-collapsible containers.
- Non-vented IV sets: Designed for use with flexible plastic IV bags, which collapse naturally as fluid is delivered without requiring atmospheric venting.
- Pump IV administration sets: Tubing engineered for compatibility with electronic infusion pumps — not interchangeable with standard gravity sets in pump applications.
- Blood administration sets: Dedicated IV sets with integrated 170–260 micron filters for the safe transfusion of blood products; not a substitute for standard IV tubing.
There are several variations of IV sets for different purposes. For example:
-
Primary vs Secondary: A primary set is used for the main fluid infusion. A secondary (or “piggyback”) set can attach to the primary line for additional medications.
-
Macrodrip vs Microdrip: Macrodrip sets deliver larger drops (commonly 10–20 drops per mL) and are used for rapid or large-volume infusions. Microdrip sets (60 drops/mL) deliver very small drops, allowing more precise control of low-flow infusions (often used in pediatrics or critical care).
-
Extension and Y-site Sets: Extension sets simply lengthen the tubing. Y-set or multi-lumen sets have additional ports or connectors allowing multiple infusions or easy access to the line.
Specialty Sets: Some IV sets include integrated filters (to catch particulates) or are made with amber tubing to protect light-sensitive medications.

Step-by-Step Guide
1. Gather Necessary Information
-
Total Volume to be Infused (mL): The amount of fluid to be given.
-
Time (minutes): The total time over which the fluid should be delivered.
-
Drop Factor (gtts/mL): The number of drops in one mL, found on the IV tubing package (common factors: 10, 15, 20, or 60 gtts/mL).
2. Use the Formula
[ \text{Drops per minute} = \frac{\text{Volume (mL)} \times \text{Drop factor (gtts/mL)}}{\text{Time (minutes)}} ]
Examples:
-
For a macrodrip (20 gtt/mL), 100 mL/hr: [ (100 \times 20)/60 = 33.3 \approx 33 \text{ drops/min} ]
-
For a microdrip (60 gtt/mL), 100 mL/hr: [ (100 \times 60)/60 = 100 \text{ drops/min} ]

- Identify your drop factor requirement first: Calculate your required infusion rate and confirm whether a 10, 20, or 60 gtt/mL set matches your clinical protocol — the drop factor printed on packaging must match your rate calculations exactly.
- Match venting to container type: Use a vented IV set with rigid glass IV bottles; use a non-vented IV set with flexible plastic IV bags. Mismatching these will interrupt flow.
- Confirm pump compatibility before ordering pump sets: Pump IV administration sets are validated for specific infusion pump models — verify tubing compatibility with your pump manufacturer before bulk procurement.
- Select primary or secondary tubing based on therapy type: Use primary IV tubing for single continuous infusions; add secondary IV tubing for piggyback antibiotic or medication delivery without disrupting the primary line.
- Use blood administration sets exclusively for blood products: Standard IV tubing does not include the required blood filter — never substitute a standard IV set for blood or blood product transfusion.
- Consider connector type for catheter compatibility: Luer-lock connectors provide a secure threaded fit and are preferred in most clinical settings; confirm connector type matches your catheter or access device.

What is an IV administration set?
An IV administration set — also called an IV giving set, IV infusion set, or IV tubing — is a sterile, single-use assembly of tubing and components designed to deliver fluids, medications, or blood products from a fluid bag or bottle directly into a patient's bloodstream via a venous access device. A standard set includes a piercing spike, drip chamber, flexible tubing with roller clamp, one or more injection ports, and a distal Luer-lock connector.
-
What is the difference between a macro-drip and a micro-drip IV set?
The difference is the drop factor — the number of drops delivered per millilitre. A macro-drip IV administration set delivers 10 or 20 drops per millilitre and is used for standard fluid infusion and rapid resuscitation. A micro-drip IV set delivers 60 drops per millilitre, which allows more precise manual control over low flow rates and is commonly used in paediatric infusion, critical care, and IV hydration therapy protocols.
-
Which drip set should I use — 10, 20, or 60 gtt/mL?
The correct drop factor depends on your prescribed infusion rate and clinical protocol. A 10 gtt/mL set is suited to rapid, high-volume fluid delivery such as emergency resuscitation. A 20 gtt/mL set is the most commonly stocked general-purpose configuration for routine IV fluid and medication infusion. A 60 gtt/mL micro-drip set is used where precise low-volume delivery is required, including paediatric therapy and medspa IV hydration kits. Always confirm the drop factor on the packaging matches your rate calculations.
-
What is the difference between a vented and non-vented IV set?
A vented IV set includes an air-inlet filter that allows air to enter a rigid glass bottle as fluid drains, maintaining the pressure balance needed for continuous flow. A non-vented IV set is designed for use with flexible plastic IV bags, which collapse naturally under atmospheric pressure and do not require venting. Using a non-vented set with a glass bottle will result in flow stopping as a partial vacuum forms. Always match venting type to your fluid container.
-
Can I use a standard gravity IV set with an infusion pump?
No. A pump IV administration set is specifically engineered to match the tubing material, wall thickness, and cassette dimensions required by a particular infusion pump model. Using a standard gravity IV set in an electronic infusion pump not validated for that tubing may produce inaccurate delivery rates and is not appropriate for clinical use. Always confirm pump-specific tubing compatibility with your pump manufacturer before ordering.
-
What IV sets are available for EMS and emergency responders?
EMS teams and emergency responders typically use macro-drip IV sets at 10 gtt/mL for rapid fluid administration in the field. These gravity sets require no pump infrastructure, are simple to prime and deploy, and are compatible with standard IV bags used in pre-hospital care. Mountainside Medical supplies IV sets for EMS in bulk at wholesale pricing with free US shipping on orders over $100.
-
Do I need a medical licence to purchase IV administration sets from Mountainside Medical?
Certain products within the IV administration sets collection require a valid medical or clinical licence to purchase. Mountainside Medical serves licensed healthcare professionals including clinics, hospitals, EMS agencies, dental and veterinary practices, and medspas. Have your licence details available when creating an account. For questions about purchasing eligibility, contact sales@mountainside-medical.com or +1 (888) 687-4334.
-
What brands of IV sets does Mountainside Medical carry?
Mountainside Medical stocks IV administration sets from Exel International and Hospira/ICU Medical — brands recognised by hospital procurement teams and clinical professionals across the United States. These manufacturers produce hospital-grade, sterile, single-use IV tubing and infusion sets in macro-drip and micro-drip configurations.
-
Can I use a standard IV administration set for blood product transfusion?
No. A blood administration set is a distinct product category that includes an integrated 170–260 micron filter specifically designed to remove micro-aggregates from packed red blood cells, platelets, and fresh frozen plasma. Standard IV tubing does not include this filter and is not appropriate for blood product transfusion. Always use a dedicated blood administration set for transfusion procedures.
