This FAQ is taken from Flow matters COVID-19 edition, updated July2021. Read the full edition here. 

Yes.

NHF use on COVID-19 patients has been observed to:

  • Keep patients off mechanical ventilation and help them stay off.
  • Lower the rate of mortality.
  • Be successfully used outside of ICU settings
  • Reduce length of stay.


“[NHF] use is associated with a reduction in the rate of invasive mechanical ventilation and overall mortality in patients with COVID-19 infection.” - Patel et al. 2020.


The number of organisations who have published evidence based guidelines recommending the use of NHF for COVID-19 patients continues to grow:

  • World Health Organisation
  • National Institutes of Health
  • National Health Commission of the Peoples Republic of China
  • Surviving Sepsis Campaign
  • Australia and New Zealand Intensive Care Society
  • European Respiratory Society
  • International expert consensus statement
  • Expert recommendations from a French panel consisting of members from various intensive care societies
