What This Guide Helps With

Troubleshooting touchscreen, display, button, and control response issues that may prevent safe setup, therapy control, or alarm acknowledgement.

Step-by-Step Troubleshooting

Ensure Patient Safety First

Confirm the AC3 Optimus is not actively supporting a patient before troubleshooting the touchscreen or control interface.

If the pump is in use or needed for immediate therapy, have clinical staff transfer to another verified IABP or follow the facility’s emergency clinical escalation process.

Expected: Patient support is maintained without relying on a pump with questionable controls.

Why it matters: The AC3 Optimus uses touchscreen-guided setup and therapy interaction, so an unreliable interface can affect setup, therapy adjustment, and alarm response. Teleflex describes the AC3 Optimus as using visual prompts on a high-definition touchscreen during setup and therapy initiation.

If this step protects the patient and the device is removed from active use, continue troubleshooting only when safe.

Verify the Reported Control Problem

Power the pump on in a safe, non-patient-use area and observe the reported symptom.

Check whether the issue is:

Expected: The failure mode is clearly confirmed and documented.

If the interface works normally after restart and repeated checks, document the finding and return only if the device passes all required operational checks.

Check AC Power and Battery Status

Connect the pump to a known-good hospital-grade outlet.

Confirm the AC power indicator, charging status, and battery status appear normal.

If available, compare behavior on AC power versus battery power.

Expected: The control interface behaves the same on stable AC power and battery power, or a power-related pattern is identified.

Why it matters: Low battery, poor charging, or unstable input power can cause startup, display, or touchscreen symptoms that look like control failure.

If stable power resolves the issue, complete functional checks and document the power source problem.

Inspect the Power Cord and External Connections

Inspect the power cord, strain relief, plug, and inlet for looseness, damage, bent prongs, or signs of overheating.

Verify the cord seats firmly into the pump and outlet.

Expected: No damaged power components are found and the pump receives stable power.

If a damaged cord or loose connection is found, remove the device from service until corrected and retested.

Perform a Controlled Power Cycle

With the device off the patient and safe to test, power the pump down normally.

Wait briefly, then power it back on and observe startup behavior.

Check whether the screen loads normally, touch response returns, and controls respond during basic menu navigation.

Expected: The interface initializes normally and responds consistently.

If the touchscreen remains frozen, blank, delayed, or inaccurate, continue troubleshooting.

Check for Screen Contamination or Touch Interference

Inspect the touchscreen surface for fluid, gel, cleaning residue, adhesive, glove powder, cracks, or pressure from a screen protector.

Clean the screen using facility-approved cleaning methods and allow it to dry fully.

Expected: The touchscreen is clean, dry, intact, and free of anything that could interfere with touch response.

If cleaning restores normal operation, repeat basic control checks and document contamination as the likely cause.

Inspect for Physical Damage

Inspect the display bezel, touchscreen glass, housing, cart handle area, and control panel area for cracks, impact marks, liquid intrusion evidence, or loose sections.

Check whether the issue appeared after transport, drop, cleaning, or movement between care areas.

Expected: No obvious external damage is present.

If physical damage or liquid intrusion is suspected, stop troubleshooting, label the device Out of Service, and send for repair evaluation.

Verify Physical Buttons and Control Inputs

Check whether any physical buttons, knobs, or external controls respond normally.

Look for stuck, jammed, loose, or damaged controls.

Expected: Controls should move normally and respond consistently.

Why it matters: A stuck or failed physical control can make the device appear frozen or prevent normal screen navigation.

If a control is physically stuck or damaged, remove the pump from service.

Check Display Behavior During Startup

Observe whether the display is:

Expected: Startup behavior is stable and repeatable.

If the display is blank, frozen, distorted, or rebooting repeatedly, the issue is likely more than simple user-interface contamination.

Confirm Alarm and Indicator Behavior

Trigger only safe, non-patient operational checks appropriate for the facility and observe whether audible/visual alarms, indicator lights, and screen messages function.

Expected: Alarm indicators and screen messages display and clear normally.

Why it matters: If the touchscreen cannot acknowledge alarms or the display cannot show prompts, the pump may not be safe for clinical use.

If alarms cannot be viewed, acknowledged, or cleared normally, remove the pump from service.

Check for Accessory or External Device Interference

Disconnect nonessential external accessories, cables, or data connections that are not needed for basic bench startup.

Restart the pump and reassess touchscreen/control response.

Expected: The interface response should not depend on optional external connections.

If the issue disappears after removing an accessory or external connection, isolate and inspect that accessory before returning the pump to service.

Compare Against a Known-Good Unit if Available

If another AC3 Optimus is available, compare startup time, screen response, button response, and visible prompts under the same safe conditions.

Expected: The suspect pump should behave similarly to the known-good unit.

Why it matters: Side-by-side comparison helps separate actual device failure from unfamiliar workflow or expected startup behavior.

If the suspect pump is clearly slower, frozen, or inconsistent, remove it from service.

Do Not Attempt Internal Display or Control Board Repair During Floor Troubleshooting

Do not open the pump, reseat internal display cables, replace boards, or perform internal calibration unless authorized and properly trained with the correct service documentation.

Expected: Troubleshooting remains limited to safe external checks.

Why it matters: An IABP is a life-support device. Interface failures should be escalated rather than worked around.

If the Problem Persists

If the touchscreen or control interface remains unresponsive, inaccurate, frozen, blank, delayed, or unreliable after external checks, common user-accessible causes have been ruled out.

The AC3 Optimus should be:

Do not return the pump to service if therapy setup, alarm acknowledgement, display prompts, or control input cannot be verified reliably.

Knowing when to stop is proper troubleshooting, especially on an intra-aortic balloon pump used for mechanical cardiac support. Teleflex identifies the AC3 Optimus as an IABP intended to provide therapy across challenging patient conditions, including severe arrhythmias, which reinforces the need for reliable controls before clinical use.

Clinical Use Tip

Do not troubleshoot touchscreen or control problems while the AC3 Optimus is actively supporting a patient. Move the patient to another verified IABP or alternate support pathway first, then evaluate the suspect pump only when safe. A touchscreen that works intermittently should be treated as unsafe until the failure is corrected and verified.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Clinical staff reported that the Teleflex AC3 Optimus touchscreen would not respond during setup and therapy screens could not be advanced."

Cause

What was observed during troubleshooting.

Example:
"Verified touchscreen was intermittently unresponsive after power cycle and cleaning; AC power, battery status, external connections, and screen contamination were ruled out."

Resolution

What action was taken.

Example:
"Removed AC3 Optimus from service, labeled Out of Service, documented suspected control interface failure, and sent for bench/vendor repair evaluation."

Helpful Details to Include (If Known)

Final Thought

For an intra-aortic balloon pump, control interface reliability is a patient safety issue, not just a usability problem. Start with power, screen condition, external connections, and obvious physical damage, but stop before internal repair unless properly authorized. Clear CCR documentation helps the next technician or vendor reproduce the failure and prevents an unreliable pump from being returned to patient care.

That is successful troubleshooting.
