Nasal high flow confers benefits that conventional therapies cannot
It's a significantly more sophisticated form of respiratory support, that includes the provision of dynamic, positive airway pressure, and reduction of dead space.
The airway hydration resulting from heating and humidifying the air is critical to facilitating comfortable treatment but is equally valuable in preserving mucociliary function. This is why it's at the heart (or more accurately lungs) of this therapy.
As with any treatment, patient comfort is a significant factor. One of the standout features of NHF is the level of respiratory support that can be achieved without the downsides of a mask.
