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 ...
Another type of device is a humidified high flow nasal cannula which enables flows exceeding a person's peak inspiratory flow demand to be delivered via nasal cannula, thus providing F I O 2 of up to 100% because there is no entrainment of room air. [73] This also allows the person to continue to talk, eat, and drink while still receiving ...
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.

In a study that looked for viral RNA in air samples taken near patients with COVID-19, no correlation was found between finding viral RNA and mechanical ventilation, high flow nasal cannula, nebuliser treatment or non-invasive ventilation. [15] However data are still lacking for many AGPs.
heated humidified high-flow therapy Heated humidified high-flow therapy, also known as high flow nasal cannula (HFNC) or high flow therapy (HFT), is a type of respiratory support that delivers a flow of medical breathing gas to a patient of up to 60 L/min and 100% oxygen through a large bore nasal cannula. originally used for neonates, it is ...
The nasal spray was first approved by the FDA in 2019 as a supplemental treatment, along with an oral medication, for the approximately one-third of people with MDD who struggle with treatment ...
Newer methods of preoxygenation include the use of a nasal cannula placed on the patient at 15 LPM at least 5 minutes prior to the administration of the sedation and paralytic drugs. High flow nasal oxygen has been shown to flush the nasopharynx with oxygen, and then when patients inspire they inhale a higher percentage of inspired oxygen.
This can take the form of oxygen delivered via nasal cannula or non-rebreather mask. Patients who require additional support may be given a high-flow nasal cannula which has an added function of providing positive pressure on the alveoli, can warm and humidify air and decrease required inspiratory effort of the patient.
