Abstract<\/strong><\/p>\n

This review provides insights into the management of mechanical ventilation during venovenous extracorporeal membrane oxygenation (VV-ECMO) for severe acute respiratory distress syndrome (ARDS). It focuses on strategies to minimize ventilator-induced lung injury (VILI) by employing ultra-lung-protective ventilation, exploring key parameters like tidal volume, plateau pressure, and driving pressure.<\/p>\n

Key Points<\/strong><\/p><\/blockquote>\n

    \n
  1. Lung Rest Strategy<\/strong>: VV-ECMO enables a significant reduction in tidal volume (\u22644 mL\/kg), respiratory rate, and plateau pressure, facilitating ultra-lung-protective ventilation to minimize VILI.<\/li>\n
  2. Ventilation in Landmark Trials<\/strong>: The CESAR and EOLIA trials demonstrated reduced mortality with ECMO, highlighting ultra-protective ventilation strategies but emphasizing the need for individualized care.<\/li>\n
  3. Driving Pressure and Mortality<\/strong>: Driving pressure (\u0394P) >14 cmH\u2082O is strongly associated with increased mortality, making it a critical parameter for adjustment during VV-ECMO.<\/li>\n
  4. PEEP Optimization<\/strong>: Proper positive end-expiratory pressure (PEEP) management is crucial to prevent lung derecruitment and overdistension, with patient-specific adjustments often required.<\/li>\n
  5. Mechanical Power<\/strong>: The energy delivered to the lungs by the ventilator (mechanical power) is a key determinant of VILI. Ultra-protective strategies aim to maintain mechanical power \u226410 J\/min.<\/li>\n
  6. Role of Spontaneous Breathing<\/strong>: Allowing spontaneous breathing can preserve diaphragmatic function but risks patient self-inflicted lung injury (P-SILI) if not carefully managed.<\/li>\n
  7. Prone Positioning<\/strong>: Combining VV-ECMO with prone positioning enhances oxygenation and facilitates ECMO weaning, though implementation remains limited due to logistical challenges.<\/li>\n
  8. Apneic Ventilation<\/strong>: Near-apneic ventilation, involving minimal tidal volume and driving pressure, shows promise in reducing VILI but requires further validation.<\/li>\n
  9. Advanced Monitoring Tools<\/strong>: Techniques like electrical impedance tomography (EIT) and transpulmonary pressure monitoring aid in optimizing PEEP and ventilation strategies.<\/li>\n
  10. Weaning from ECMO<\/strong>: Transitioning from ECMO to mechanical ventilation requires careful monitoring of tidal volumes, respiratory efforts, and gas exchange to ensure patient stability.<\/li>\n<\/ol>\n
