![]() ![]() Next, remove the plastic or rubber caps from the fluid bag and the plastic spike located at the top of the tubing. To do this, move the roller to the narrow end of the device, thus pinching the tubing closed. To introduce fluid into the primary line, first close the roller clamp on the primary line. The following method of setting up your IV assembly should be followed to reduce the risk of introducing foreign bodies and air into the patient: The vent will allow for fluid flow out of the bottle as air flows into the bottle. If you are setting up fluids from a glass jar, you will need a primary set that contains a vent, located above the drip chamber. Therefore most primary tubing will likely be designed without a vent. Since most IV fluids are available in plastic bags that collapse as the fluid infuses, it is unnecessary to vent the tubing. The primary tubing will have several components attached, including a plastic spike, a drip chamber, a roller clamp, the syringe tip and locking collar, and medication ports. Note, only sets designed for use with glass bottles will include a vent. It is recommended that you familiarize yourself with each accessory your facility uses and how it works prior to using it, as there are some variations between manufacturers. The infusion set may also have inline filters, stopcocks, access ports, and shutoff clamps. Macrodrip sets deliver between 10 and 15 gtt per milliliter. Macrodrip sets produce larger drops and thus infuse fluid at a greater rate. Every microdrip set will deliver 60 drops (gtt) per milliliter. Microdrip sets produce smaller drops and thus infuse fluid slower. This may be preferable to allow for patient mobility, temporarily independent of an IV pole.Īlthough there are many IV tubing manufacturers, there are two general sizes: micro drip and macrodrip sets. There may be a smaller extension tube between the infusion set and the IV catheter hub. One end of plastic tubing is connected to the bag of fluid and the other is connected to the hub of the IV catheter. IV fluids are infused through flexible tubing, often called an infusion set or primary set. ![]()
