Best answer


High-flow nasal cannula (HFNC)is aheated and humidified system that allows prescribed fraction of inspired oxygen (FIO2) levels to be delivered at very high flow rates. Let鈥檚 now consider how HFNC can help our patients improve their respiratory disease. There are three main proposed benefits of HFNC:

  • What is a nasal cannula used for?

  • 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.

  • What is the typical flow rate of a traditional nasal cannula?

  • Traditional nasal cannula delivers flow rates of 2鈥? L / min. However, patients with respiratory distress can have much higher peak inspiratory flow rates which can cause the patient to entrain room air into the lungs. This can result into an oxygen dilution, and the patient will not receive the precise amount of oxygen that is desired.

  • What are the different types of nasal cannulas?

  • 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. HFNC is the medical abbreviation for a high-flow nasal cannula.
