What This Guide Helps With

This guide addresses situations where the Hamilton C3 ventilator:

• Exhibits delayed touchscreen response
• Freezes intermittently or permanently
• Shows unregistered or erratic touchscreen input

Focus is on external, logical troubleshooting first—power, connections, and software checks—before assuming internal hardware failure.

Step-by-Step Troubleshooting

Verify Power Supply

• Ensure the ventilator is connected to a verified working AC outlet.
• Check the battery level; low battery can cause UI lag.
• Why: Inconsistent power can cause touchscreen responsiveness issues.

Reboot the Ventilator

• Power off the unit using proper shutdown procedure.
• Wait 30 seconds, then power back on.
• Why: Temporary software glitches are often resolved by a clean restart.

Check External Connections

• Disconnect any non-essential peripherals (USB drives, external sensors, printer).
• Confirm that circuit connections and breathing system components are properly seated.
• Why: Conflicts with external devices can cause system lag.

Inspect Touchscreen Surface

• Clean the screen with a soft, lint-free cloth. Avoid harsh chemicals.
• Check for moisture, condensation, or physical damage.
• Why: Debris or moisture can interfere with touch detection.

Monitor Software Status

• Check for on-screen messages indicating software updates or errors.
• Verify that the system is running the latest approved firmware.
• Why: Outdated or interrupted updates can reduce touchscreen performance.

Reset Non-volatile Memory (if instructed by software)

• Follow the C3 software prompts for safe reset of touchscreen parameters.
• Why: Certain UI parameters can become corrupted and resetting may restore normal operation.

If the Problem Persists

All external and software-level checks have been performed. Touchscreen lag or freezing is likely due to internal hardware issues (touch panel controller or mainboard).

• Remove the ventilator from service.
• Label as Out of Service.
• Send to Hamilton-approved service or internal bench evaluation.
• Reinforce: Stopping at this point is proper troubleshooting to prevent patient risk.

Clinical Use Tip

• Do not attempt touchscreen troubleshooting during active ventilation.
• Move the patient to another ventilator before testing.
• Only perform touchscreen checks when patient safety is not compromised.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
“Clinician reports the ventilator touchscreen is slow or unresponsive.”

Cause

What was observed during troubleshooting.

Example:
“Observed intermittent lag, temporary freezes, and unregistered inputs; power and connections verified.”

Resolution

What action was taken.

Example:
“Ventilator rebooted; peripherals disconnected; screen cleaned; firmware verified. Issue persists → unit labeled Out of Service and sent for service.”

Helpful Details to Include

• AC outlet tested and verified
• Battery charged
• Peripherals disconnected
• Screen cleaned and visually inspected
• Firmware version checked
• Final device status: Out of Service

Final Thought

Touchscreen responsiveness issues can originate from minor software glitches or signal interruptions, but persistent lag often signals internal hardware failure. Logical, stepwise troubleshooting protects patient safety, ensures accurate documentation, and avoids unnecessary disassembly. Document each step using the CCR method.

That is successful troubleshooting.
