The O-Two single-use open CPAP delivery system provides incredibly accurate CPAP delivery for such a compact device. By minimizing the pressure drop on inspiration and the peak pressure on expiration, the O-Two single-use open CPAP delivery system produces a more uniform CPAP pressure throughout the respiratory cycle. This provides a lower work of breathing for the patient when compared to other, commonly used, prehospital devices.

The CPAP from O-Two is such an innovative design it was awarded the 2011 EMS World Innovation Award.
