Short Summary:
This study demonstrates that SafeBVM’s Sotair flow-limiting device significantly improves manual ventilation control, ensuring peak airway pressures remain within safe limits. Conducted with 41 respiratory therapy students, the study compared manual ventilation using the Sotair device to mechanical ventilation across normal and decreased lung compliance settings.
Key findings:
- Comparable peak inspiratory pressures between manual ventilation with Sotair and mechanical ventilation (15 vs 13 cmH2O with normal lung mechanics; 23 vs 23 cmH2O with decreased lung compliance).
- Effective tidal volume (VT) delivery, with ventilation performance slightly lower with Sotair (452 vs 474 for normal lung compliance; 312 vs 460 ml for low compliance) compared to mechanical ventilator.
- Participants effectively adapted to changing lung compliance, demonstrating the device’s ability to enhance manual ventilation consistency.
- The flow-limiting feature prevented excessive inspiratory pressures, potentially reducing the risk of barotrauma and gastric insufflation.
Conclusion:
The Sotair device bridges the gap between manual and mechanical ventilation, providing controlled, safe, and effective manual ventilation. This study reinforces its potential to improve patient outcomes in both emergency and controlled settings, making it a valuable innovation for respiratory care.
