Administration Set Troubleshooting & Best Practices

This module addresses common troubleshooting scenarios and clinical best practices specific to Bridge IV administration sets in gravity infusion workflows.

Issue: Infusion is running too fast or too slow. First, recount the drip rate over a full 60 seconds. If the rate has drifted, readjust the roller clamp with small incremental movements. Common causes of rate drift: patient position change (arm elevation changes venous pressure), roller clamp slippage on wet or kinked tubing, or IV pole height change. Gravity flow rate is directly proportional to the height difference between the container and the insertion site — raising the pole increases flow, lowering it decreases flow.

Issue: No drip or flow has stopped. Check for: (a) roller clamp or slide clamp fully closed — open it; (b) kinked tubing — straighten the line; (c) empty container — replace with a new bag; (d) catheter occlusion — assess the IV site and flush per protocol; (e) drip chamber overfilled — invert the chamber briefly to lower the fluid level back to halfway.

Issue: Air bubbles in the tubing. Small bubbles trapped along the tubing walls are common and generally not clinically significant in peripheral gravity infusions. However, large bubbles or continuous air should be addressed: clamp the line, tap the tubing section to move bubbles toward the drip chamber (they will rise out of the fluid path), and re-prime if necessary. Never run a line with visible large air pockets toward the patient.

Best practices for Bridge clinics: Change administration sets every 96 hours per CDC guidelines for continuous infusion, or with each new infusion session in outpatient settings. Label each set with the date and time of first use. Dispose of used sets in appropriate biohazard waste. Never reuse a set that has been disconnected — always use a fresh set for each patient encounter.
