IV Fluid Therapy Components: Complete Setup Guide

Intravenous (IV) Infusion System Components

A standard gravity or pump-driven IV setup includes:

1. IV Bag/Container: Sterile fluid (0.9% NaCl, D5W, LR, Plasma-Lyte, blood products).
2. IV Tubing (Administration Set):
   • Macrodrip (10, 15, 20 gtt/mL) for rapid infusion.
   • Microdrip (60 gtt/mL) for precise pediatric/medication delivery.
   • Needle-free connectors, backcheck valves, filters (0.22 µm for TPN, blood).
3. IV Cannula/Catheter: Peripheral (14–24G), midline, PICC, central line (CVC, port).
4. Drip Chamber: Visual flow monitoring; air trap.
5. Flow Regulator: Roller clamp (gravity) or infusion pump (syringe, volumetric, PCA).
6. Needle-Free Connector / Safety Port: Luer-activated valve for intermittent access; reduces needlesticks.
7. IV Pole: Adjustable height; 2–4 hooks for multiple bags.

Additional Equipment

• Infusion Pumps: Volumetric (maintenance), syringe (meds), PCA (patient-controlled analgesia), elastomeric (portable).
• Pressure Bags: Rapid infusion (trauma, surgery).
• Warming Devices: Blood/fluid warmers for massive transfusion.
• Smart Pumps: Drug libraries, dose error reduction systems (DERS).

Key Principles

• Aseptic technique throughout.
• Verify "5 Rights" (patient, drug, dose, route, time) + documentation.
• Monitor site for infiltration, phlebitis, infection (INS standards).
• Label all lines (medication, rate, date/time).
