| Outline of Final Research Achievements |
The vigorous spontaneous effort during mechanical ventilation in severe ARDS will cause ventilator-induced lung injury, contributing to increased mortality in ARDS. Thus, short term use of muscle paralysis was proven to reduce the motality of severe ARDS, but alternative strategy is needed considering it will potentially be associated with muscle weekness.
This study shows that the application of PEEP can reduce spontaneous breathing, leading to better distribution of lung aeration in CT, and less histological lung injury. This is the first demonstration that we can reduce the harm of spontaneous breathing in severe ARDS without paralyzing patients. This will be quite important because we can minimize the spontaneous breathing associated lung injury, but with preserving muscle function.
