Summary

Extracorporeal membrane oxygenation (ECMO) has been widely used in patients with severe acute respiratory distress syndrome (ARDS). But how to choose mechanical ventilation strategy is still not clear for severe ARDS patients supported by ECMO. Our previous work found that, compared to the traditional "lung rest" strategy, transpulmonary pressure guide new lung ventilation strategy can better maintain lung volume reduction lung collapse, atelectasis occurs. The severe ARDS patients receiving ECMO therapy were randomized divided into a new ventilation strategy group and the conventional ventilation strategy group. The new ventilation strategy is transpulmonary pressure guide ventilator setting method, and the conventional ventilation strategy is Extracorporeal Life Support Organization (ELSO) guide ventilation method. Compare the difference between the two groups of patients in lung injury, and explore the lung protection mechanism of new lung ventilation strategies guided by transpulmonary pressure. Our research group considered that transpulmonary pressure guide new lung ventilation strategy can provide more effective lung protection. And it will be further used in clinical work.

Conditions

  • Respiratory Distress Syndrome, Adult

Interventions

DEVICE

New lung ventilation strategy

New ventilation strateg: pressure assist control mode; inspiratory pressure was lowered to keep Ppeak less than 25cmH2O; set the PEEP at such a level that expiratory transpulmonary pressure stays between 0 and 5 cmH2O; respiratory rate of 10 breaths per minute; FiO2 less than 0.5.

DEVICE

Conventional ventilation strategy

Conventional ventilation strategy: pressure assist control mode; keep the Ppeak between 20 and 25 cmH2O; set PEEP between 10 and 15 cmH2O; respiratory rate of 10 breaths per minute; FiO2 less than 0.5.
