High-Flow Nasal Oxygen and Noninvasive Ventilation for COVID-19

Hasan M Al-Dorzi et al. Crit Care Clin. 2022 Jul.

Abstract

High-flow nasal oxygen (HFNO) and noninvasive ventilation (NIV) via facemask or helmet have been increasingly used in managing acute hypoxemic respiratory failure (AHRF) owing to COVID-19 with the premise of reducing the need for invasive mechanical ventilation and possibly mortality. Their use carries the risk of delaying intubation and nosocomial infection transmission. To date, most studies on the effectiveness of these modalities are observational and suggest that HFNO and NIV have a role in the management of AHRF owing to COVID-19. Trials are ongoing and are evaluating different aspects of noninvasive respiratory support in patients with AHRF owing to COVID-19.

Keywords: Acute hypoxemic respiratory failure (AHRF); COVID-19; HFNO; Noninvasive ventilation.
