*A review of studies comprising the body of NHF evidence found the majority used F&P Optiflow™ systems

High flow nasal cannula (HFNC), high flow therapy (HFT), high flow oxygen/therapy (HFO/T), nasal high flow (NHF), high flow nasal prongs (HFNP), high flow oxygen (HFO), humidified high flow nasal cannula (HHFNC), heated, humidified high flow nasal cannula (HHHFNC), humidified high flow therapy (HHFT), nasal insufflation or just plain high flow (HF).

While many terms are used to describe NHF, one name stands out: Optiflow NHF therapy

Optiflow NHF therapy from Fisher & Paykel Healthcare is at the forefront of its field, featuring in hundreds of publications and prestigious journals such as NEJM and JAMA.

Using Optiflow NHF therapy as a first-line treatment (both pre-intubation and post-extubation) may reduce a patient's escalation "up the acuity curve," resulting in better patient outcomes.

This guideline provides recommendations for the following populations:
  • Acute hypoxemic respiratory failure
  • Post-operative
  • Post-extubation respiratory failure

Extubation to Optiflow NHF therapy: Dr Hernández

This video depicts extubation to Optiflow NHF therapy, and is based on the procedure used by Dr. Hernández and his colleagues in the following studies: Hernández et al. JAMA. 2016 (April)1 and Hernández et al. JAMA 2016 (Oct.)2

ROX Index explained

The ROX index can be used to monitor patients and predict the likelihood of NHF therapy success or failure. 

It combines three common measurements: FiO2, SpO2, and respiratory rate, and it is based on two known facts about sicker patients. 1. They require more oxygen. 2. They have a higher respiratory rate.

The index has been validated in a multi-center prospective study conducted with 191 patients with pneumonia.*
