Short Summary
This porcine experimental study demonstrates that SafeBVM’s Sotair flow-limiting device significantly improves manual ventilation safety during prolonged transport, reducing the risks associated with excessive airway pressures and flow rates.
Key Findings
- Reduced Peak Inspiratory Pressure (PIP): The Sotair device effectively lowered PIP to 31.2 cmH₂O (95% CI: 29.9–32.4) compared to 72.8 cmH₂O in the sham device group (p<0.0001), minimizing the risk of barotrauma and lung injury.
- Controlled Inspiratory Flow Rate (IFR): Sotair maintained a more stable IFR (20.7 L/min, 95% CI: 19.1–22.4), significantly lower than the sham device group (62.4 L/min, 95% CI: 55.8–69.1, p<0.0001), which would help prevent lung overdistension.
- Consistent Performance in BVM & ETI Settings: The Sotair device effectively controlled ventilation parameters in both bag-valve-mask (BVM) and endotracheal intubation (ETI) settings, ensuring safer ventilation delivery across prehospital scenarios.
Conclusion
The SafeBVM Sotair device improved manual ventilation by preventing dangerously high airway pressures and excessive flow rates, reducing lung injury risk during simulated prolonged transport. These results demonstrate that Sotair enhances ventilation safety and consistency, making it a very useful airway management tool for EMS providers in both prehospital and transport settings.
