Which breathing aid wins for COVID-19? HVNI vs CPAP showdown
NCT ID NCT07213518
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 108 adults with COVID-19 pneumonia who had low oxygen levels (type 1 respiratory failure). Researchers compared two breathing support methods: High-Velocity Nasal Insufflation (HVNI) and Continuous Positive Airway Pressure (CPAP). The goal was to see which one corrects low oxygen better. The study is now complete.
