. The heat and humidified high-flow nasal cannula or as most call it high-flow nasal cannula HFNC isnt just a standard nasal cannula turned up to very high flow rates. To determine whether in infants with bronchiolitis admitted to a pediatric intensive care unit PICU the starting rate for high-flow nasal cannula HFNC therapy set by the. Heliox a helium-oxygen gas mixture has been used for many decades to treat obstructive pulmonary disease.

For the HFNC treatment condition participants were started on the therapy at the lowest setting of 15Lmin of nasal cannula flow and increased by 5Lmin increments every 5. High-flow nasal cannula therapy can provide this in an alert awake patient by achieving a high-flow rate and very high amounts of FiO2 thus increasing PO2. Bronchiolitis is one of the most common pediatric inpatient diagnoses accounting for 100 000 inpatient admissions per year.

The optimal HFNC rate to decrease effort of breathing for children less than 3 years old is between 15 and 2 Lkgmin with the greatest improvement expected in children.
