ECMO Circuit Troubleshooting: Bedside Quick Reference

ECMO alarms and circuit changes can become overwhelming quickly—especially when the patient, circuit and underlying physiology are all changing at once.

ECMO Circuit Troubleshooting: Bedside Quick Reference from The Acute Care Atlas is designed to help clinicians approach common ECMO problems systematically.

Rather than simply listing alarms, the guide emphasizes a bedside sequence: assess the patient, trace the circuit, recognize the physiologic pattern, identify likely causes, and escalate appropriately.

Designed for quick reference during clinical education, orientation and bedside review, this guide focuses on adult VA and VV ECMO and reinforces an important principle: treat the patient and understand the circuit—not just the alarm.

What you'll learn

• A systematic approach to ECMO circuit assessment
• Chugging/chatter and impaired venous drainage
• Low-flow patterns and changes in circuit pressures
• Air and circuit-integrity emergencies
• Oxygenator dysfunction and gas-exchange problems
• VA versus VV considerations
• When a circuit change may actually represent bleeding, tamponade, cannula position, tension physiology or another patient problem
• Findings requiring immediate ECMO-team escalation

Intended audience

ECMO nurses, critical-care nurses, acute-care NPs/PAs, APP fellows, ECMO specialists in training, and experienced clinicians who want a concise adult VA/VV ECMO bedside refresher.
