Of the time, air enters the stomach when ventilating the lungs with a manual resuscitator.9

The Solution

SafeBVM’s award winning Sotair device is funded by grants and contracts from NIH, NSF, Military and Air Force. It revolutionizes manual ventilation with its flow-limiting valve, regulating air flow above 55 LPM, thereby preventing high peak air pressures.  Regulation of air flow has been shown to reduce excessive volume and respiratory rates, reducing the risk of over ventilation and hyperventilation.

Sotair’s design is intuitive and only requires 30 seconds for training. The device provides real-time, multi-sensory feedback (haptic, auditory, visual) to guide providers, enhancing adaptability and consistency in patient care no matter the patient type or lung condition.

Pressure Delivered During Manual Ventilation

Sotair® limits the flow of air at 55 L/min. For an average adult, this corresponds to a maximum pressure of approximately 20 cmH2O. Air enters the stomach beyond 20 cmH2O causing gastric insufflation.

ADULT Sotair® Device Features

  • FDA 510(k) cleared for Adult, single patient use
  • Prevents high air flow rates (>55LPM) during manual ventilation, thereby limiting peak air pressures. Regulation of airflow helps reduce excessive tidal volumes and breath delivery rates, minimizing the risk of over-ventilation and hyperventilation
  • Intended to minimize air entry into the stomach
  • Immediate real-time haptic auditory and visual feedback
  • Decreases provider variability and improves consistency of ventilation
  • 30 second basic training

How Does Sotair® Work?

When flow rates delivered with the bag exceed 55 L/min, the device activates and limits the flow of air providing haptic, auditory, and visual feedback to the user.

During the COVID-19 pandemic, it was anticipated that there will be a shortage of mechanical ventilators. An alternative may be to implement manual ventilation in these situations. 47 volunteer providers completed two, one-hour manual ventilation sessions. Providers were randomized to complete their initial session either with or without Sotair®.

Sotair® Performance, Closer to a Ventilator's


Peak pressures (p>.0001) and tidal volumes (p>0.0001) were significantly improved with the Sotair® device and authors concluded that extended manual ventilation may be feasible with a safety device, which may reduce barotrauma, under-ventilation and over-ventilation.10


Grant 1U54HL143541 (NHLBI) funded a 40-provider pilot bench evaluation of Sotair® with North Providence Fire Station. Implementation of Sotair® showed a 36% improvement in manual ventilation.11   Learn More
