Brief Summary
Acute respiratory syndrome distress (ARDS) is a clinical common syndrome with high mortality. Mechanical ventilation (MV) is the cornerstone of management of ARDS but can lead to ventilator-induced lung injury. Positive end-expiratory pressure (PEEP), as one of main component of MV, has been widely used in the clinical practice. However, the PEEP selection is still a difficult problem for moderate to severe ARDS patients. EIT, an imaging tool evaluating the regional ventilation distribution at the bedside, can achieve the individual PEEP selection for all mechanically ventilated patients. Our previous study found that moderate to severe ARDS patients with higher recruitability could benefit from EIT-guided PEEP. This article compared the effect of PEEP titrated guided by EIT with fraction of inspired oxygen (FiO2)-PEEP table on the clinical outcomes in patients with higher recruitability.
Eligibility Criteria
Inclusion Criteria: 1. Age≥18 years 2. Moderate-to-severe ARDS, defined by the ARDS Definition Task Force in the Berlin definition (partial pressure of arterial oxygen \[PaO2\]:FiO2 ratio ≤200 mmHg with a PEEP ≥5 cmH2O) 3. RI ratio \> 0.5 measured for clinical reasons in the previous 24 hours 4. Diagnosis of ARDS less than 72 hours Exclusion Criteria: 1. Expected to be mechanically ventilated for less than 48 hours 2.
