A portable extracorporeal membrane oxygenation (ECMO) system offers rapid circulatory support for cardiopulmonary failure. This mobile ECMO cart demonstrated feasibility and effectiveness in diverse critical patient scenarios.

Area of Science:

  • Cardiovascular Medicine
  • Biomedical Engineering
  • Critical Care

Background:

  • Cardiopulmonary failure necessitates rapid extracorporeal support.
  • Existing systems may lack portability and swift initiation capabilities.

Purpose of the Study:

  • To report on the development and clinical application of a portable extracorporeal membrane oxygenation (ECMO) system.
  • To evaluate the system's efficacy, safety, and patient outcomes in various critical conditions.

Main Methods:

  • A mobile cart-based ECMO system was assembled using standard components (Sci-Med oxygenator, centrifugal pump, heat exchanger).
  • The system was designed for rapid priming (5-10 min) and femoral cannula insertion.
  • Extracorporeal membrane oxygenation (ECMO) was applied to 29 patients over 30 months for diverse indications.

Main Results:

  • The portable ECMO system provided adequate circulatory support in 28 out of 29 patients.
  • Device flows ranged from 0.2 to 6.0 L/min.
  • Six patients survived, including three from elective percutaneous transluminal coronary angioplasty support and three from cardiac arrest during catheterization.

Conclusions:

  • A portable ECMO system can be rapidly deployed to manage acute cardiopulmonary failure.
  • The system shows promise for improving outcomes in critical care settings.
  • Further studies are warranted to optimize its use and expand indications.
