High velocity nasal insufflation (HVNI) is a unique form of non-invasive ventilatory support in spontaneously breathing patients. The mechanisms of action are not pressure-based. HVNI has proven non-inferior to CPAP in multiple randomized controlled trials. Dr. McQueen discusses these important ventilatory modalities, among others.
Describe the difference between high velocity and high flow.

Summarize the findings of RCT's which demonstrate non-inferiority of HVNI to nCPAP.
