A wide flow range (2 – 60 L/min) facilitates the treatment of a broad patient group in a variety of hospital areas staffed by many types of clinicians.

Nasal high flow therapy (NHF) is recommended in several clinical applications among recently published clinical practice guidelines.

A review of the studies referenced by the clinical practice guidelines showed that the majority of the studies used flows of ≥ 45 L/min, i.e., flow rate matters.
