What This Guide Helps With

Troubleshooting suspected slow infusion or under-delivery caused by programming, administration sets, syringes, loading, occlusion, setup, or pump performance.

Step-by-Step Troubleshooting

1. Ensure Patient Safety First

Do not evaluate suspected flow inaccuracy while the Novum IQ pump is delivering medication or fluid to a patient.

• Notify nursing, pharmacy, and the responsible clinical team.
• Transfer the infusion to another verified pump when clinically appropriate.
• For high-risk medication or a critically ill patient, use an alternate pump whenever available and appropriate.
• Have the clinical team assess the patient for possible effects of delayed or insufficient therapy.
• Preserve the administration set, syringe, and disposables when they may be needed for investigation.

Expected outcome: The patient continues receiving the prescribed therapy without relying on the affected pump.

The Novum IQ platform includes Large Volume Pump and Syringe Pump configurations. Record which pump type was involved before continuing. Baxter’s current correction applies to all identified Novum IQ LVP and Syringe Pump units, so verify that required corrective actions have been completed before returning the device to service.

2. Clarify the Reported Under-Delivery

Interview the reporting clinician and determine:

• Whether the complaint involves the Novum IQ LVP or Syringe Pump.
• Programmed rate and volume to be infused.
• Medication or solution being delivered.
• Expected versus observed delivery time or remaining volume.
• Whether the infusion stopped, slowed, alarmed, or appeared to continue normally.
• Whether the concern was based on bag volume, syringe position, patient response, electronic documentation, or elapsed time.
• Whether boluses, pauses, KVO operation, secondary infusions, or rate changes occurred.
• Whether the pump displayed an alarm, blank Run screen, or unusual status indication.

Expected outcome: The complaint is defined well enough to reproduce or evaluate accurately.

Do not conclude that the pump is inaccurate solely from visual estimation of a flexible IV container or syringe markings.

3. Review Programming and Infusion History

With the pump removed from patient use:

• Review the programmed rate, VTBI, dose, concentration, patient weight, and delivery mode.
• Confirm that the selected drug-library entry and care area were appropriate.
• Check for pauses, delayed starts, completed infusions, KVO transitions, secondary-infusion programming, or clinician-initiated rate changes.
• Compare pump history with the medication administration record when available.
• Determine whether EMR auto-programming or manual programming was used.

Expected outcome: The programmed therapy agrees with the intended order and no pause, mode change, or programming discrepancy explains the apparent under-delivery.

If incorrect programming or a documented pause explains the complaint, document the finding and stop equipment troubleshooting.

4. Inspect the Pump and Installation

Inspect the pump externally for:

• Fluid intrusion or medication residue.
• Cracked housing, damaged door, bent components, or impact damage.
• A loose pole clamp or pump installed at an unusual angle.
• Dirt, adhesive residue, or foreign material in the tubing or syringe-loading area.
• Damaged sensors, loading points, clamps, or mechanical contact surfaces.
• Unusual heat, odor, vibration, or sound.

Expected outcome: The pump is clean, securely mounted, and free of visible damage that could interfere with delivery.

Remove the pump from service immediately if there is fluid intrusion, physical damage, overheating, burning odor, or an abnormal drive sound.

5. Verify the Administration Set or Syringe

For a Novum IQ Large Volume Pump:

• Confirm that the administration set is specifically compatible with the pump.
• Verify that the set is within its expiration date and has not been reused.
• Check the tubing for kinks, closed clamps, collapsed sections, excessive stretching, or improper routing.
• Inspect the pumping segment for deformation, contamination, or incorrect placement.
• Confirm that the container is vented when required.
• Check that any filter, check valve, extension set, or needleless connector is appropriate and not obstructed.

For a Novum IQ Syringe Pump:

• Confirm that the syringe manufacturer, model, and size are approved and correctly selected.
• Check that the syringe barrel is properly secured by the barrel clamp.
• Verify that the plunger is captured correctly by the drive mechanism.
• Inspect for a stiff plunger, damaged barrel, leaking connection, excessive extension tubing, or an incompatible syringe.
• Compare the displayed syringe identification with the syringe physically installed.

The Syringe Pump identifies the loaded syringe partly by sensing its barrel diameter, making correct loading and syringe selection essential.

Expected outcome: The disposable component is compatible, undamaged, correctly identified, and properly loaded.

If replacing or correctly loading the administration set or syringe resolves the concern, complete a functional test, document the result, and stop.

6. Check for Flow Restrictions and Occlusion

Inspect the entire simulated fluid path from the container or syringe to the test destination.

Look for:

• Closed roller clamps or slide clamps.
• Kinked tubing.
• Blocked filters or connectors.
• Partially seated luer connections.
• Check valves installed backward.
• Excessive downstream pressure.
• Pinched tubing at the pump door.
• Air trapped in a filter or flow path.
• A stiff syringe plunger.

During patient use, also ask whether the IV catheter, patient position, infiltration, or a positional occlusion may have caused resistance. Clinical staff must evaluate the patient access site.

Expected outcome: The test fluid path is open and offers no abnormal resistance.

A downstream restriction may reduce or interrupt delivery before an occlusion alarm activates, especially at low rates.

7. Reload the Disposable Correctly

Use a new compatible disposable for testing.

For the LVP:

• Open the pump door.
• Remove the administration set.
• Inspect the loading channel.
• Reload the set in the correct sequence without stretching or twisting it.
• Ensure each loading point indicates proper engagement before closing the door.

For the Syringe Pump:

• Remove the syringe.
• Verify the barrel, flange, and plunger position.
• Reload the syringe fully into the barrel clamp and plunger drive.
• Confirm that the pump identifies the correct syringe.

Baxter’s published correction instructions include reloading the tubing or syringe when a blank Run screen occurs during an infusion. Any pump with an unresolved blank Run screen or incomplete corrective action requires escalation.

Expected outcome: The disposable is recognized, the Run screen is normal, and the pump starts without loading or setup alarms.

8. Confirm Test Setup and Environmental Conditions

Before performing an accuracy test:

• Allow the pump, fluid, administration set, and syringe to stabilize at room temperature.
• Use distilled or deionized water unless another approved test fluid is required.
• Remove air from the test path.
• Position the pump and collection point according to the approved test procedure.
• Minimize elevation differences, siphoning, back pressure, and evaporation.
• Use calibrated test equipment with adequate resolution for the selected flow rate.
• Allow sufficient test duration for the rate being evaluated.

Expected outcome: The test setup does not introduce a false under-delivery result.

The Novum IQ LVP accuracy specification depends on administration-set material and flow rate. The FDA clearance summary lists different accuracy limits at very low rates, so results must be compared with the applicable manufacturer specification rather than one universal tolerance.

9. Perform a Flow-Rate Accuracy Test

Using a calibrated infusion-device analyzer or approved gravimetric method:

• Install a new compatible administration set or approved syringe.
• Prime the system completely.
• Program a representative clinical flow rate.
• Allow the pump to reach stable operation.
• Measure delivered volume over the required test interval.
• Compare the result with the applicable Novum IQ service specification.
• Repeat the test if the first result is unexpected.
• Test at additional low, medium, or high rates when required by hospital procedure or the manufacturer’s service documentation.

For the Syringe Pump, use the exact approved syringe manufacturer and size required by the test procedure. Published accuracy varies by compatible syringe, with most listed as having a different tolerance from certain other syringe types.

Expected outcome: Measured delivery remains within the manufacturer’s specified tolerance for the pump type, disposable, syringe, rate, and test conditions.

If the pump passes repeatable testing, investigate the original disposable, programming history, access-site resistance, and clinical setup before returning the device.

10. Repeat the Test With Known-Good Components

When the pump initially fails or produces inconsistent results:

• Replace the administration set or syringe with another approved component from a different package.
• Replace extension tubing, filters, and connectors.
• Repeat priming and loading.
• Verify the analyzer or measurement method with a known-good pump when available.
• Repeat the same rate and test duration.

Expected outcome: The test distinguishes a disposable or setup problem from a repeatable pump-performance problem.

If the original disposable fails but the pump passes consistently with known-good components, retain the disposable and lot information for investigation.

11. Determine Final Device Status

Return the pump to service only when:

• Required Baxter corrective actions are confirmed complete.
• No physical or fluid damage is present.
• Compatible disposables load and operate normally.
• The pump produces no unexplained alarms or blank screens.
• Flow accuracy passes the applicable specification.
• Results are repeatable.
• The pump completes all required functional and safety checks.

Expected outcome: The pump is verified safe and suitable for clinical use.

If the Problem Persists

If under-delivery is repeatable with compatible disposables, a controlled test setup, and calibrated test equipment, common external causes have been ruled out.

The pump should be:

• Removed from service.
• Labeled Out of Service.
• Preserved with the involved set, syringe, and lot information when available.
• Sent for manufacturer-authorized repair or qualified bench evaluation.
• Reported through the organization’s safety or risk-management process when patient harm, high-risk medication, or a serious delivery discrepancy may have occurred.

Do not perform unapproved internal adjustment, calibration, motor, sensor, or pumping-mechanism repair. Knowing when to stop and escalate is proper troubleshooting.

Clinical Use Tip

Never troubleshoot suspected flow inaccuracy on an active patient. Transfer the infusion first, especially when vasoactive drugs, insulin, anticoagulants, sedation, neonatal therapy, or other high-risk medications are involved.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Nursing reported that the Baxter Novum IQ LVP was programmed at 100 mL/hr but appeared to deliver substantially less fluid than expected."

Cause

What was observed during troubleshooting.

Example:
"Inspection found the compatible administration set twisted and incompletely seated in the pump loading channel, creating restricted flow."

Resolution

What action was taken.

Example:
"Removed the pump from patient use, installed and primed a new compatible set, completed flow-accuracy testing at representative rates, and returned the pump to service after all results passed specification."
