Troubleshooting Dialysis Machine Alarms

Dialysis machines are equipped with safety alarms to protect patients from mechanical failures, blood leaks, pressure imbalances, or improper fluid flow. Understanding these alarms and how to troubleshoot them is critical for nurses, technicians, and caregivers.

Common Alarms & Solutions:
Arterial Pressure Alarm: Check for kinked lines or blocked access.

Venous Pressure Alarm: May indicate clotting or resistance in return lines.

Air Detector Alarm: Ensure air is not present in the extracorporeal circuit.

Conductivity/Temperature Alarm: Verify dialysate calibration and temperature settings.

Blood Leak Detector Alarm: Change dialyzer immediately and test for cross-contamination.

Power Failure Alarm: Activate manual return or emergency backup systems.

Best Practices:
Always monitor patients visually.

Respond to alarms promptly and calmly.

Maintain updated training on each machine model.

Keep a troubleshooting checklist near the unit.
