Podcast 715: Heated High Flow O2

Podcast 715: Heated High Flow O2

Contributor: Nick Hatch, MD

Educational Pearls:

  • High flow nasal cannula (HFNC) or "heated high flow" can deliver higher oxygen levels than nasal cannula
  • It typically is used as an "intermediate" between oxygen via nasal cannula and other non-invasive positive pressure devices, such as BiPAP
  • Can modify both the FiO2 and flow rate
  • Maximum flow rate is typically 60 liters per minute (compare that to a typical breath that is 30-40 L/min)
  • Humidification of HFNC is important due to risk of epistaxis from drying out the nasal mucosa
  • Large energy expenditure to humidify airflow by a patient in respiratory distress, so humidified oxygen may help decrease this metabolic demand
