Performance and Safety of an Integrated Portable Extracorporeal Life Support System for Adults

Area of Science:

• Cardiovascular Medicine
• Critical Care Medicine
• Medical Device Engineering

Background:

• Extracorporeal membrane oxygenation (ECMO) is a vital life support measure for severe cardiac or respiratory failure.
• Interhospital transport of ECMO patients is often necessary but presents unique logistical and technical challenges.
• Evaluating the performance of portable ECMO systems is crucial for ensuring patient safety during transit.

Purpose of the Study:

• To compare the performance and safety of the Cardiohelp™ life support system against a standard ECMO circuit during interhospital transport of adult venoarterial ECMO patients.
• To assess key performance indicators and patient outcomes associated with each ECMO system.

Main Methods:

• A retrospective study comparing 16 adult patients on venoarterial ECMO during interhospital transport.
• Eight patients were supported by the Cardiohelp™ system, and eight by a standard circuit (Thoratec CentriMag pump, Maquet Quadrox-D oxygenator, Terumo CDI-500 analyzer).
• Performance metrics and patient outcomes including weaning success, survival to discharge, and circuit-related complications were analyzed.

Main Results:

• No significant differences were observed in patient demographics, successful weaning rates, survival to discharge, or duration of ECMO support between the Cardiohelp™ and standard circuit groups.
• No patient deaths were attributed to circuit failure or disruption in either group.
• The Cardiohelp™ system demonstrated significantly lower transmembrane pressure compared to the standard oxygenator at both 8-hour and 24-hour time points (p < .001 and p = .001, respectively).

Conclusions:

• The Cardiohelp™ portable life support system provides safe and effective ECMO support for adult patients during interhospital transport.
• Its performance is comparable to traditional ECMO circuits, with the added benefit of potentially lower transmembrane pressure.
• The Cardiohelp™ system is a reliable option for maintaining ECMO support during patient transfers.
