Optiflow nasal high flow delivers respiratory support to your patients, by providing heated, humidified air and oxygen at flow rates up to 70 L/min through the unique Optiflow nasal cannula and delivered by a device such as the Airvo 2 nasal high flow system.

1. Firstly, it’s called many things, High flow nasal cannula (HFNC), high flow therapy (HFT), high flow oxygen / therapy (HFO/T)...
2. It can deliver high levels of oxygen, but it is significantly more sophisticated than that – the higher rates of flow (independent of oxygen) confer benefits that oxygen alone cannot...
Evidence shows that when NHF is applied early enough (in patients who respond to therapy), you should see improvement in oxygenation, RR, and 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 nasal high flow (NHF) outcome in the first few hours of treatment, and beyond.
The ROX*index* combines three common measurements: FiO2, SpO2, and respiratory rate,...

Clinical observations, investigative research, and expert opinions highlight that NHF therapy is not considered to represent an increased risk of HCW infection via contact, droplet, or airborne transmission routes.
Wilson et al. 2021 compared the effect of respiratory activity, noninvasive respiratory support, and facemasks on aerosol generation.
