High-flow nasal cannula (HFNC) therapy is anoxygen supply system capable of delivering up to 100% humidified and heated oxygen at a flow rate of up to 60 liters per minute. All settings are controlled independently allowing for greater confidence in the delivery of supplemental oxygen as well as better outcomes when used.

What is a high-flow nasal cannula (HFNC)?
WHAT IS A HIGH-FLOW NASAL CANNULA (HFNC)? WHAT IS A HIGH-FLOW NASAL CANNULA (HFNC)? A high-flow nasal cannula (HFNC) is a heated and humidified system that allows prescribed fraction of inspired oxygen (F I O 2) levels to be delivered at very high flow rates.
What is a nasal cannula and how does it work?
A nasal cannula is a medical device to provide supplemental oxygen therapy to people who have lower oxygen levels. There are two types of nasal cannulas: low flow and high flow. The device has two prongs and sits below the nose. The two prongs deliver oxygen directly into your nostrils.
What is the difference between low flow and high flow cannulas?
A patient in distress with an increase in demand on a low-flow nasal cannula will entrain room air into the lungs, resulting in oxygen dilution. HFNC with higher flow rates will result in greater delivery of oxygen into the lungs, thus producing less entrainment of room air.
How much oxygen does a low flow nasal cannula deliver?
They can deliver up to 60 liters of oxygen per minute. Low flow nasal cannulas can only deliver a nasal cannula flow rate of 4-6 liters of oxygen per minute. They don’t provide humidified or heated oxygen.
