Using an Ambulatory IV Infusion Pump at Home
Ambulatory infusion pumps allow patients to receive intravenous medications or fluids safely while maintaining mobility at home. This guide provides clear instructions on preparation, line priming, connecting to your vascular access device, and responding to common safety alarms. Strict adherence to clean technique prevents infection and ensures your prescribed dose is delivered accurately.
Quick Summary
Maintain strict sterile technique, prime tubing to clear all air bubbles, and never force a flush if you encounter resistance.

Step-by-Step Guide
Clean Workspace and Gather Supplies
Thoroughly clean a hard, flat surface with disinfectant wipes and let it air-dry completely. Wash your hands with warm water and soap for at least 20 seconds, or use an alcohol-based hand sanitizer. Assemble all prescribed items: the ambulatory pump, medication cassette or bag, administration tubing, normal saline flush syringes, alcohol prep pads, and clean gloves.
Important: Check medication expiration dates and inspect the fluid for cloudiness, leaks, or floating particles before proceeding.
Inspect and Prime the Administration Tubing
Remove the administration set from its sterile packaging, keeping the protective caps in place. Spike the medication bag or attach the cassette according to manufacturer instructions. Prime the tubing slowly until fluid fills the entire line and all visible air bubbles are cleared from the tubing and drip chamber.
Important: Ensure all air is eliminated before connecting to your catheter to reduce the risk of air embolus and avoid triggering upstream or downstream pressure alarms.
Load the Pump and Verify Settings
Insert the cassette or position the primed tubing into the pump mechanism until it clicks securely into place. Turn on the device and verify that the battery level is sufficient for the planned infusion duration. Cross-check the programmed rate, volume to be infused, and time settings against your home health prescription sheet.
Disinfect and Flush Your Catheter
Put on clean gloves and inspect your PICC, midline, or port site for swelling, redness, or tenderness. Vigorously scrub the needleless injection cap (hub) with an alcohol or chlorhexidine prep pad for at least 15 seconds, allowing it to air-dry completely. Attach a saline syringe and use a pulsing push-pause technique to confirm catheter patency.
Important: Stop immediately and do not force fluid if you meet resistance or feel pain when flushing; forcing fluid can dislodge a clot or rupture the line.
Connect the Line and Start the Infusion
Remove the cap from the primed pump tubing without touching the sterile tip, and firmly screw it onto your catheter's cleaned hub using the luer-lock mechanism. Open all clamps on the tubing and the catheter lumen. Press the 'Run' or 'Start' button on the pump, then verify that the display indicates active delivery and the line remains open.
Secure the Device and Wear the Carrying Pouch
Place the ambulatory pump into its specialized carrying pouch, backpack, or waist pack. Ensure the tubing has adequate slack and is not pinched, twisted, or caught in clothing seams. Route the tubing close to your body to prevent accidental snagging during normal daily movement.
Disconnect and Flush Post-Infusion
When the pump signals that the infusion is complete, pause the device and close all clamps. Wash hands, disconnect the tubing, scrub the catheter hub for 15 seconds, and flush the line with prescribed saline and heparin solution. Dispose of single-use tubing and medication reservoirs according to your home infusion agency's medical waste guidelines.
