HFNC compared to NIV

HFNC:

- Comfort - Higher comfort  Eating, drinking and speaking less impaired 

- Airway pressure and PEEP  - Excessive pressure is likely avoided, Flow-dependent PEEP, limited to <6 cmH20 

- Anatomical dead space  - Mostly reduced 

- CO2 washout  - Nasopharyngeal CO2 washout 

- Mucociliary function  - Maintained due to heated and humidified gas application 

- Pulmonary effects  - Increased EELV, Reduced WOB, Moderate increase of transpulmonary pressure 

- Extra pulmonary effects  - Reduction of cardiac preload 

- P-SILI/VILI  - Lower risk 

- Skin breakdown/ sores  - Less likely
