WebOct 2, 2024 · Flow devices (high-flow or low-flow devices) such as nasal cannula, aerosol mask, rebreathing mask, venturi mask, etc are used for oxygen therapy. ... Calculation of the total flow of oxygenated air. An entrainment ratio is defined as the ratio of oxygen flow to atmospheric airflow from the adaptor to the aerosol mask. FiO 2. WebHeated humidified high-flow therapy, often also high flow nasal cannula(e) or high flow nasal oxygen, is a type of respiratory support method that delivers ... The constant flush of the upper airway creates a reservoir that reduces room-air entrainment to such an amount that it becomes a true fraction of inspired oxygen as set by the device. ...
