How quickly does Nasal High Flow work?


Evidence shows that when NHF is applied early enough (in patients who respond to therapy) you should see improvement in oxygenation, RR, dyspnea within 15-30 mins. Monitoring should continue beyond this of course.

The recent addition of the ROX index, calculated from 3 data points collected at the bedside, can provide an indicator of NHF outcome in the first few hours of treatment, and beyond.
