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.

Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
