Systems on Top of Nasal Cannula Improve Oxygen Delivery in Patients with COVID-19: a Randomized Controlled Trial.

ABSTRACT:

Background

Treating hypoxemia while meeting the soaring demands of oxygen can be a challenge during the COVID-19 pandemic.

Objective

To determine the efficacy of the surgical facemask and the double-trunk mask on top of the low-flow oxygen nasal cannula on arterial partial pressure of oxygen (PaO₂) in hypoxemic COVID-19 patients.

Design

Randomized controlled trial.

Participants

Hospitalized adults with COVID-19 and hypoxemia treated with the low-flow nasal cannula were enrolled between November 13, 2020, and March 05, 2021.

Interventions

Patients were randomized in a 1:1:1 ratio to receive either the nasal cannula alone (control) or the nasal cannula covered by the surgical facemask or the double-trunk mask. Arterial blood gases were collected
