Extracorporeal Membrane Oxygenation for Respiratory Failure: A Narrative Review

Area of Science:

• Critical Care Medicine
• Cardiopulmonary Physiology
• Respiratory Support Technologies

Background:

• Extracorporeal membrane oxygenation (ECMO) is increasingly utilized for respiratory failure in intensive care units.
• While acute respiratory distress syndrome is a primary indication, ECMO also addresses other causes of refractory hypoxemia and hypercapnia.

Purpose of the Study:

• To provide a comprehensive overview of extracorporeal membrane oxygenation (ECMO) for respiratory failure.
• To discuss the physiology, indications, management, and complications associated with ECMO in intensive care settings.

Main Methods:

• This narrative review synthesizes current knowledge on ECMO for respiratory failure.
• It covers ECMO physiology, patient selection, circuit management, troubleshooting, complications, and weaning strategies.

Main Results:

• Veno-venous ECMO is most common, but veno-pulmonary and veno-venoarterial configurations may benefit specific patient groups.
• Effective patient selection and meticulous circuit management are crucial for successful ECMO outcomes.

Conclusions:

• Understanding ECMO physiology and management is essential for clinicians as its application expands.
• Optimizing ECMO use requires careful consideration of indications, contraindications, and potential complications.
