The tubing for these sets includes a roller clamp ( Fig. To calculate IV drip rates, you must know this information. Sometimes the drop factor is also stated on the top part of the chamber. The package label states the drops per milliliter (gtt/mL). For example, Baxter-Travenol macrodrip sets deliver 10 gtt/mL, so 10 drops drip in the drip chamber (10 gtt = 1 mL) Abbott sets deliver 15 gtt/mL, so 15 drops drip in the drip chamber (15 gtt = 1 mL). Drops per milliliter differ according to the manufacturer. Infusion sets without a small needle in the chamber are called macrodrip ( Fig. To deliver 1 mL of fluid to the patient/client, 60 drops drip in the drip chamber (60 gtt = 1 mL). Sets with a small needle in the chamber are called microdrip because their drops are small.
The top of the infusion set contains a chamber. These consist of plastic tubing attached at one end to the IV bag and at the other end to a needle or catheter inserted into a blood vessel. IV fluids are administered through infusion sets. If you have any doubt about the correct IV solution, always double-check with another healthcare professional.Ĭommon abbreviations for IV fluids are listed in Table 6-1.ĭrip chambers for macrodrip and microdrip IV tubing. Physicians and healthcare providers order IV fluids and the IV flow rate. It is essential to choose the correct IV fluid to avoid serious fluid and electrolyte imbalance that may occur from infusing the wrong solution. IV fluids are packaged in sterile plastic bags or glass bottles. Chapter 7 presents rules and calculations for special types of IV orders. This chapter presents basic knowledge-types of fluids, equipment, calculation of drip rates, and recording intake. Texts such as Plumer’s Principles and Practice of Intravenous Therapy (Lippincott Williams & Wilkins, 2006) present detailed and extensive information.
Calculating basic IV drip rates: milliliters over a number of hours, milliliters per hour (mL/hour), and drops per minute (gtt/minute)Īdministration of parenteral fluids and medications by the IV (intravenous) route is common medical practice and is a specialty within nursing and health care.
