high flow nasal prongs flow rate
Respiratory failure is distressing for patients and treatment modalities currently in use may be associated with discomfort from upper airway drying tightly fitting facemasks and resultant complications such as skin breakdown. High flow always delivers much higher flows than MV.

High Flow nasal prongs are not variable performance.
. Once prescribed flow rate is reached assess requirement for supplemental oxygen. Salters 16SOFT Nasal Cannulas provide a higher level of comfort and softness to oxygen users. 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.
Over time the cannula may irritate the lining of the nose causing soreness or occasional bleeding. Their FiO2 delivery is fixed. High-flow nasal oxygen therapy HFNOT is increasingly used as part of both ward-based and critical care management of respiratory failure.
Start the high flow nasal cannula system in room air ie. And it stretches as you move to reduce dragging and pressure on the tender. Many patients get supplemental oxygen through a nasal cannula--flexible plastic tubing with prongs that fit into the nose.
The attached 4-Foot Oxygen Supply Tube is exceptionally soft so it feels light to the touch. Flow rate for HFNP Therapy is the same for all patients regardless of medical condition. 16SOFTs nasal prongs and faceplate are soft and gently curved conforming naturally to your nostrils and upper lip.
The aspect of low flow cannulae which makes them deliver variable FIO2 is their flow rate in proportion to the minute volume which can be either very close to MV or almost insignificant compared to it. Nasal prongs should not completely occupy the nares. It takes gas is able to heat it to 37 o C with a 100 relative humidity and can deliver 021 - 100 fraction of inspired oxygen FiO 2 at flow rates of up to 60 liters.
