Contributor: Aaron Lessen, MD

Educational Pearls:

  • High flow nasal cannula (HFNC) has become more utilized with COVID pandemic
  • Multiple studies have shown this method improves both oxygenation and ventilation
  • Newer studies have shown the respiratory benefit of HFNC  vs normal oxygen in patients suffering from CHF and those with do not intubate orders who are experiencing respiratory distress.  
  • Heated high flow is another option to provide ventilator and oxygen support to patients who either do not need or do not want to be intubated
