Heated humidified high-flow therapy, often simply called high flow therapy, is a type of respiratory support that delivers a flow of medical gas to a patient of up to 60 liters per minute and 100% oxygen through a large bore or high flow nasal cannula. Primarily studied in neonates, it has also been found effective in some adults to treat ...
The nasal cannula (NC) is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. This device consists of a lightweight tube which on one end splits into two prongs which are placed in the nostrils curving toward the sinuses behind the nose, and from which a mixture of air and oxygen flows.

high flow nasal oxygen therapy High flow nasal oxygen therapy is a system which uses a heated and humidified blend of air and oxygen delivered via a high flow nasal cannula (HFNC). It is a standard of care in some clinical situations for infants, children, and preterm neonates and is finding increasing use for adults. [37] high flow oxygen device
In a continuous-flow system, oxygen is provided to the user continuously. It does not matter if the user is exhaling or inhaling as oxygen is flowing from the time the system is activated. Below the oxygen mask is a rebreather bag that collects oxygen during exhalation and as a result allows a higher flow rate during the inhalation cycle. [5]

The total flow of gas (oxygen plus the entrained air) will be greater than the patient's peak inspiratory flow so the delivered F I O 2 is independent of their respiratory pattern. [ 5 ] A controlled F I O 2 is particularly important for patients whose ventilation is dependent on hypoxic drive , [ 5 ] as may be seen in patients with chronic ...

A non-rebreather mask (NRB, non-rebreather, non-rebreather facemask, etc.) is a device used in medicine to assist in the delivery of oxygen therapy.A NRB requires that the patient can breathe unassisted, but unlike a low-flow nasal cannula, the NRB allows for the delivery of higher concentrations of oxygen.
