High flow oxygen therapy supports breathing in people with: High flow oxygen therapy is for in people in respiratory distress who still have low oxygen levels despite trying traditional oxygen therapy. Why do patients need high flow oxygen therapy?.Better clearance of fluids (secretions) due to humidified air.When compared to conventional oxygen therapy, delivered through a face mask, high flow nasal cannula oxygen therapy offers: By decreasing the effort of breathing and creating a small amount of positive pressure in the upper airways, this therapy helps improve oxygen delivery. High flow oxygen therapy helps reduce the effort your body needs to put into breathing. What is the difference with conventional oxygen therapy?.The applied gas is heated to best match the body temperature (37☌) and humidified targeting ideal body saturation vapor pressure.

High-flow oxygen therapy, commonly referred to in the medical field as HFNC (high-flow nasal cannula) or HFNO (high-flow nasal oxygen), is a method of respiratory support in which a high flow (liters per minute) of medical gas is delivered to the patient through an interface (nasal cannula) designed to create a flush of the upper airway. High-flow oxygen therapy differs from these in that it is used for acute and chronic respiratory problems and is an appropriate option for treating patients with severe or critical COVID-19. Most of these are conventional oxygen therapies. Have you often seen actors in film lying in hospital beds with nasal oxygen tubes?
