New Strategies in Treating Respiratory Failure: NIV and HFNO as 
complementary therapy 


Noninvasive ventilation (NIV) or the delivery of positive pressure ventilation delivered through a noninvasive interface has become more common as its benefits are increasingly recognized. NIV has proven efficacy for hypercapnic respiratory failure, especially that due to COPD exacerbations. High-flow nasal cannula (HFNO) comprises an air/oxygen blender, an active humidifier, a single heated circuit, and a nasal cannula. HFNO has shown promise to treat hypoxic respiratory failure. This webinar will explore a new strategy in the treatment of respiratory conditions. Specifically, this presentation will discuss how HFNO may play a useful complementary role during breaks from NIV.


Learning Objectives:

Upon completion of this activity, the participant will be able to:

Discuss indications for NIV and HFNO

Compare and contrast physiologic actions of NIV and HFNO

Demonstrate how HFNO and NIV can work in complementary fashion
