This system is often used with air-entrainment nebulizers to provide humidification and oxygen therapy. The total flow of gas (oxygen plus the entrained air) will be greater than the patient's peak inspiratory flow so the delivered FIO2 is independent of their respiratory pattern.
This system is often used with air-entrainment nebulizers for humidification and oxygen therapy. The total gas flow exceeds the patient's peak inspiratory flow, resulting in a constant FIO2 independent of their respiratory pattern.
