Lung-protective ventilation with low-tidal volume improves outcome among patients with Acute Respiratory Distress Syndrome. The use of low tidal volume ventilation in the Emergency Departments has been shown to provide early benefits for critically ill patients.
A systemic review and meta-analysis of studies comparing outcomes of patients receiving low tidal volume ventilation vs. those who did not receive low tidal volume ventilation.
The authors identified 11 studies with approximately 11000 patients. The studies were mostly observational studies and there was no randomized trials.
The authors included 10 studies in the analysis, after excluding a single study that suggested Non-low tidal volume ventilation was associated with higher mortality than low tidal volume ventilation (1).
Comparing to those with NON-Low tidal volume ventilation in ED, patients with Low-Tidal volume ventilation in ED were associated with:
Although there was low quality of evidence for low tidal volume ventilation in the ED, Emergency clinicians should continue to consider this strategy.
