Confidence in the delivery of blended humidified oxygen.
When supplemental oxygen is required, Optiflow can provide flows up to 60 L/min to meet peak inspiratory demand, thereby reducing O2 dilution by room air.
In the diagram at right, the maximum oxygen flow from a face mask is limited to approximately 10 L/min which is not sufficient to meet the patient's peak inspiratory demand. To reconcile the difference, room air is entrained diluting the oxygen being delivered.
By contrast, Optiflow is able to meet this patient's peak inspiratory demand of 30 L/min ensuring an accurate delivery of FiO2 to the patient.
