The inspired O2FLO™ is an easy-to-use system that delivers warm, moist gas
at high flow rates that generates positive airway pressure. It acts as a bridge
between low-flow oxygen therapies and nasal continuous positive airways
pressure(CPAP). At high-flow oxygen therapy as 2 L/kg/min, applying an appropriate
nasal cannula, a positive pressure between 4 cm and 8 cm H2O could be achieved.*
